Fire fighting pipe is a kind of normal carbon steel pipe for conveying water, gas and other fire suppression agents. It's usually in red. But the exterior of the light-wall pipes is galvanized silvery. The installation of a red steel pipe is only to be used as a wet sprinkler system. Dry and wet pipe sprinkler systems (including pre-action pipe sprinkler systems) are allowed to install galvanized pipes.

Since the installation of the first fire protection system, black steel has been the traditional leader of the fire sprinkler pipe market because of its strength, durability, and extreme resistance to heat exhibited. With a melting point between a whopping 2,600°F and 2,800°F (1,427°C and 1,538°C), steel pipe can withstand the heat of burning buildings, it even can keep water flowing over a fire.

Steel Pipe for Fire Protection Systems
Fire suppression pipes are easy to form, bend, and fabricate, which can be manufactured in various sizes, shapes and configurations. Steel pipe has been the main material of sprinkler piping systems for a long time. Steel is considered strong, durable and resistant to fire. With a melting point of about 2,700°F, the fire service pipe can withstand the heat of a burning building.

Steel fire sprinkler pipes can be connected by screw thread, welded connection, rolling connection and groove cutting connection. Threading is only allowed for Schedule 40 or heavier pipe. However, if a lighter wall pipe is listed by a specialized thread testing laboratory, NFPA 13 (National Fire Protection Association) will allow the lighter wall pipe threads.

ASTM A500 Steel Pipe(2022年09月21日)

tianchuangpipe — 2022-09-20T17:33:38+0900

https://www.tianchuangpipe.com/products/astm-a500-steel-pipe.html

ASTM A500 Steel Pipe
ASTM A500 is the standard specification for circular, square, and rectangular tubes of cold-formed welded and seamless carbon steel structures. ASTM A500 standard is the most common specification for Hollow Structural Sections in North America. The correct way to specify the circular HSS section is to represent the outer diameter in decimal inches to three decimal places (i.e., 5.563 x 0.250) according to the nominal wall thickness.

Why ASTM A500 Steel Tube?
Since ASTM A500 is a structural specification, circular high-speed steel produced according to this ASTM A500 specification is suitable for structural applications and general construction purposes.

The specified yield strength of ASTM A500 C(the most commonly available grade) is 46 ksi. The specified yield strength of A53 Grade B is 35 ksi. Yield strength increased by more than 30%. Therefore, the strength-to-weight ratio of A500 circular HSS is greater than that of the A53 pipe. So, if you do the job with round HSS, you need less steel, by weight, to do the job—the lighter it is, the lower the cost.

The tolerances of A500 are tighter than those of A53, so the HSS of the A500 circle has higher quality and less variability. If you want to know the difference between A500 pipe and the A795 pipe, continue browsing.

Round HSS has a superior surface finish and is not as lacquered as normal A53 tubes. Since this lacquer coating needs to be removed from the A53 pipe to accommodate welding and painting, so this can save money and time.

ASTM A500 Steel Gas Pipe Applications
All steel structures have their pros and cons including structural supports, building columns, highway signs, oil field services, and communication towers, to name a few. But ultimately ASTM A500 is a better choice when you need a round profile.

We encourage architects, fabricators, structural engineers, and contractors to read up on ASTM A500 and visit The Steel Tube Institute's website because it offers a wide variety of technical publications, load tables, and design aids.

As an ASTM A500 tube factory, we will provide more high quality products for sale, if you have needs, please contact us.

The Performance Test and Analysis of Hot Dip Galvanized Steel Pipe(2021年)

tianchuangpipe — 2021-11-15T11:20:53+0900

https://www.tianchuangpipe.com/products/hdg-pipe/

Hot-dip galvanized steel pipe is a square pipe formed by a series of chemical reactions in the hot-dip galvanizing pool, which is welded by steel plate or crimping. The performance and acceptance criteria of hot-dip galvanized steel pipes are as follows:

1. The performance of hot-dip galvanized steel pipes

Hot-dip galvanized steel pipe has good strength, toughness, plasticity, weldability and ductility. Its alloy layer is firmly attached to the steel base. Therefore, the hot-dip galvanized steel pipe can be formed by cold stamping, rolling, wire drawing and bending without damaging the coating.

It is suitable for general processing such as drilling, cutting, welding, cold dipping, bending and other processes. The surface of hot-dip galvanized parts is bright and beautiful, and can be directly used in engineering as required.

2. The acceptance criteria of hot-dip galvanized steel pipes

Hot-dip galvanized steel pipe is generally qualified by the appearance of the product. If there is leakage, pitting, white spots, heavy leather, bubbles, green, high frequency and other phenomena on the outer surface of the pipeline, it is judged as unqualified.

However, in the product standard, the product deviation has a specified range, that is, the allowable size deviation, because zinc hardly changes in dry air, so if we coat zinc on the surface of the steel pipe, we can prevent the steel pipe from being corroded.

3. The characteristics of hot-dip galvanized steel pipes

Smooth appearance, no zinc tumor, no burr, silvery white color, controllable thickness, optional range of 5~107um, no hydrogen embrittlement, no temperature hazard, and can meet various requirements of users. Ensure that the mechanical properties of the material remain unchanged; it can replace some hot-dip galvanizing processes with good corrosion resistance.

What is the Difference Between Galvanized Round Pipe and Hot Dip Galvanized Steel Pipe?(2021年)

tianchuangpipe — 2021-11-15T11:20:29+0900

https://www.tianchuangpipe.com/products/hdg-pipe/

There are many kinds of round pipe materials, the most common is plastic pipe or steel pipe. In addition to these two common round pipes, there are aluminum round pipes, iron round pipes, steel plated round pipes, galvanized round pipes and so on.

Today we will introduce to you the difference between galvanized round pipe and hot-dip galvanized steel pipe.

1. Introduction of galvanized round pipe and hot-dip galvanized steel pipe

1. Structure of hot-dip galvanized steel pipe

The hot-dip galvanized steel pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. The hot-dip galvanized pipe supplied by Hebei Tianchuang Pipe Co., Ltd is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip plating tank.

Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The matrix of the hot-dip galvanized steel pipe undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, its corrosion resistance is strong.
2. Structure of galvanized steel pipe

The galvanized steel pipe adjusts the production process of hot-dip galvanized pipe. The strip steel used for pipe making is first pickled. In order to remove the iron oxide on the surface of the strip steel, after pickling, it is cleaned in a tank with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. Sent into the hot dip plating tank. It is then air-dried and made into tubes. The coating layer is uniform and bright, and the amount of zinc coating is small, which is lower than the cost of producing hot-dip galvanized pipes. Its corrosion resistance is slightly worse than that of hot-dip galvanized pipe.

Ⅱ. The differences between galvanized round pipe and hot-dip galvanized steel pipe

1. The hot-dip galvanized steel pipe is snow-white but not shiny or reflective, with a lot of snowflakes on the surface, and zinc tumors (condensed zinc) on both ends.

2. The galvanized tube is shiny white and reflective, with few snowflakes, and the two ports are clean and free of zinc tumors.

The above is the introduction and the differences between galvanized round pipe and hot-dip galvanized steel pipe. The galvanized round pipe is made by chlorination or oxidation, so it has high corrosion resistance and wear resistance, and it is not easy to be corroded by moisture in the air. In addition, the color of the galvanized round pipe is cyan, and it is reflective, which is easy to identify.

Understand the National Standard Thickness of Hot Dip Galvanized Steel Pipe(2021年)

tianchuangpipe — 2021-11-15T11:20:01+0900

https://www.tianchuangpipe.com/products/hdg-pipe/

Ⅰ. What is hot-dip galvanized pipe?

In order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized.

1. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing layer is thick, the cost of electro-galvanizing is low, and the surface is not very smooth.

2. Nominal wall thickness(mm): 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5;

3. Coefficients(c): 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.

Note: The mechanical properties of steel is an important index to ensure the final use performance (mechanical properties) of the steel, and it depends on the chemical composition of the steel and the heat treatment system. In the steel pipe standard, according to different application requirements, the tensile properties (tensile strength, yield strength or yield point, elongation), hardness, toughness indexes, and high and low temperature properties required by users are specified.

1. Grades of galvanized pipe steel: Q215A; Q215B; Q235A; Q235B;

2. Test pressure value/Mpa: D10.2-168.3mm is 3Mpa; D177.8-323.9mm is 5Mpa.

Galvanized steel pipes are divided into cold galvanized pipes and hot-dip galvanized steel pipes. The former has been banned, while the latter is also promoted by the state.

Ⅱ. Characteristics of hot-dip galvanized pipe

1. The uniformity of the galvanized layer: the steel pipe sample shall not turn red (copper-plated color) after being immersed in copper sulfate solution for 5 consecutive times.

2. Surface quality: the surface of the galvanized steel pipe should have a complete galvanized layer, and there must be no unplated black spots and bubbles, and small rough surfaces and local zinc tumors are allowed.

3. Galvanized layer weight: According to the requirements of the buyer, the galvanized steel pipe can be used to determine the weight of the zinc layer. The average value should not be less than 500g/square meter, and any sample must not be less than 480g/square meter.

Hot Dip Galvanizing Layer Has Anti-corrosion Effect on Galvanized Steel Pipe(2021年)

tianchuangpipe — 2021-11-15T11:19:34+0900

https://www.tianchuangpipe.com/products/hdg-pipe/

1. The anti-corrosion effect on galvanized steel pipe

The anticorrosive zinc of galvanized steel pipe has a negative electrode potential than iron. When zinc and iron form a microbattery, zinc is the anode and iron is the cathode. When it is corroded, zinc dissolves and iron is not harmed. When the galvanized layer has small cracks or damage, the zinc will be in the form of a dedicated anode to prevent the steel at the crack or damage from rusting. This is the main feature of the galvanized layer being better than other coatings.

When hot-dip galvanized steel pipe is dipped galvanized, the zinc-iron alloy layer and the steel matrix and zinc layer are all metallurgically bonded, which is stronger than the combination of paint and steel.

2. The shielding and protective effect on galvanized steel pipe

The anticorrosive zinc layer of galvanized steel pipe has a shielding and protective effect on steel. Zinc forms a shielding layer on the surface of the steel substrate in the atmosphere or other environments. The corrosion process of zinc increases its ability to form a shielding layer. This is because zinc reacts with oxygen, carbon dioxide, and moisture in the air to form an anti-corrosion by-product basic zinc carbonate film.

The zinc-iron alloy layer between the substrate and the pure zinc layer contains 90% zinc, which has an electrochemical protective effect similar to zinc; the thicker the coating, the longer the service life, and the service life is basically proportional to the thickness.

https://www.tianchuangpipe.com/products/steel-pipe/

1. Carbon
The higher the carbon content, the higher the rigidity of galvanized steel pipe, but the worse its plasticity and toughness.

2. Sulfur
It is a harmful impurity in steel pipe products. Steels with higher sulfur content are prone to brittle cracks during high temperature pressure processing, which is usually called hot brittleness.

3. Phosphorus
It can significantly reduce the plasticity and toughness of steel, especially at low temperatures. This phenomenon is called cold brittleness. In high-quality steel, sulfur and phosphorus must be strictly controlled. But on the other hand, low carbon steel contains high sulfur and phosphorus, which can make it easy to cut, which is beneficial to improve the machinability of steel pipe products.

4. Manganese
It can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel. High-alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical properties.

5. Silicon
It can increase the hardness of steel, but the plasticity and toughness are reduced. The steel used for electrical engineering contains a certain amount of silicon, which can improve the soft magnetic properties.

6. Tungsten
It can improve the red hardness and thermal strength of steel, and can improve the wear resistance of steel.

7. Chromium
It can improve the hardenability and wear resistance of steel, and can improve the corrosion resistance and oxidation resistance of steel.

1. Introduction of W Beam Guardrail
The manufacturers of W beam guardrail understand that it cannot be ignored that the W beam guardrail is greatly affected by the environment and climate. W beam guardrail is a kind of guardrail, which is set for the avoidance of highway collision. It is the main form of semi-rigid guardrail. It is a continuous structure which is spliced with corrugated steel parapets and supported by main columns. W beam guardrail is mainly set to prevent runaway vehicles from rushing out of the roads. It is generally made of galvanized steel plates. Different specifications are adopted according to different highway grades.

First of all, the environment and climate of the city should be considered when choosing the materials for W beam guardrail installation. W beam guardrail is a product placed in outdoor environment, so it will be affected by the environment and climate. Therefore, the designers of W beam guardrail should consider not only the function and form of the product, but also the environment and climate.

2. Environmental and climatic factors to be considered in the selection of W beam guardrails
In terms of durability of W beam guardrail, we should choose a material suitable for the environment and climate. As one of the professional steel guardrail manufacturers, let me to tell you the main influencing factors.

(1) Air temperature, wind speed and ultraviolet intensity
The air temperature, wind speed and ultraviolet intensity are different in different cities. W beam guardrail, as a product in outdoor environment, always faces the wind and the sun in nature. For cities with high ultraviolet intensity, anti-ultraviolet coatings are necessary. Corrosion-resistant materials should be selected in cities with high humidity.

(2) The day and night environment
In addition, the environment during the day and night also has a great impact on traffic, especially in the night with the most traffic accidents. The lighting in night environment is based on artificial light, which is quite different in brightness and chromaticity compared with sunlight in the day. In this environment, the W beam guardrail cannot be quickly identified by human eyes. When designing the W beam guardrail, we should not only consider the daytime conditions, but also consider how to realize the functions that the W-beam guardrail should have in the nighttime environment.

The Function and Design Conditions of W Beam Guardrail(2021年)

tianchuangpipe — 2021-11-15T11:17:38+0900

https://www.tianchuangpipe.com/products/highway-guardrail/
https://www.tianchuangpipe.com/installation-standard-for-w-beam-guardrail.html

1. Introduction of W beam guardrail
People pay more and more attention to the importance of W beam guardrail. W beam guardrail is a combined, corrugated and movable steel guardrail at the opening of the central separation belt of the highway. The guardrail is composed of two corrugated steel guardrail plates and two upright posts fixedly sandwiched between them.

2. The role of W beam guardrail
In economically developed areas, the villages and towns along the highway are relatively dense, and there are many passages crossing the main line, which means that the height of embankment should be increased and the danger of highway slope will increase. Besides the high embankment height and steep slope, the width of central partition, kerb and shoulder is also short, which requires the setting of highway metal guardrails.

W beam guardrail installation can not only prevent runaway vehicles from rushing out of roads and off-road obstacles, but also prevent other objects from rushing into lanes through the central partition to cause more traffic accidents. It can also restore the normal driving direction of vehicles, minimize the damage to passengers and induce the sight.

3. Design conditions of W beam guardrail
W beam guardrail is generally divided into flexible guardrail, semi-rigid guardrail and rigid guardrail. It has certian flexibility and can absorb collision energy and avoid collision through the deformation of the beam. In addition, it has a good line-of-sight induction function, which can be coordinated with road alignment. It can be used in small radius bends with beautiful and harmonious appearance. The damaged parts are easy to replace.

Problems Needing Attention in the Installation of W Beam Guardrail(2021年09月29日)

tianchuangpipe — 2021-09-29T15:39:58+0900

https://www.tianchuangpipe.com/problems-needing-attention-in-the-installation-of-w-beam-guardrail.html

1. The key to installation of W beam guardrail
The W beam guardrails are spliced with each other and fixed on the column or beam by connecting bolts. The overlapping direction of the W beam guardrail is the key to installation. The overlapping direction should be consistent with the driving direction. If the overlapping direction is opposite to the driving direction, even a slight collision will cause greater losses.

2. Problems needing attention in the installation of W beam guardrail
The W beam guardrail should be adjusted continuously during installation. Therefore, the connecting bolts should not be tightened too early. Otherwise they will not be able to adjust the oblong holes on the plates. After adjustment, use high-strength bolts and tighten the connecting bolts as required to strictly control the torque. The adjusted W beam guardrail should form a smooth waveform to avoid local bumps. The top surface of the W beam guardrail should be coordinated with the vertical curve of the road. When the shape of the W beam guardrail is satisfactory, the bolts should be tightened. But it should be noted that the connecting bolts should not be too tight, so that the oblong holes can be used to adjust the compressive stress.

When the steel pipe-inserted corrugated beam guardrail is used in the W beam guardrail installation, the foundation should be buried synchronously with the pavement construction. Protective measures should be taken to prevent sundries from falling off the pipes. The steel pipe-inserted W beam guardrail should be blow-molded. The weld seam should be firm and flat. Each W beam guardrail should be flat, correct in size, free to twist and pull out. The corrugated beam guardrail is built on the foundation by pumping. The W beam guardrail at the opening can reach the strength of the ordinary road. Its opening flexibility is that a span of W beam guardrail can be pulled out by loosening the six bolts of two columns.

How to Install Highway Guardrails on Winding Roads(2021年09月29日)

tianchuangpipe — 2021-09-29T15:38:30+0900

https://www.tianchuangpipe.com/how-to-install-highway-guardrails-on-winding-roads.html

1. Introduction of highway guardrail
Highway guardrail is flexible. Its main function is to absorb the energy generated by collision. It also has a good visual guidance function and a beautiful appearance. It is mainly used for expressways, primary and secondary highways, provincial highways, county roads, rural roads, scenic spots, large parking lots, etc. In most cases, roads are straight. But winding roads are inevitable and it is also necessary to install highway guardrails on winding roads. Here are some methods of how to highway guardrail installation on winding roads.

2. How to install highway guardrails on winding roads
Highway guardrail for sale is generally straight plate, which is difficult to install on winding roads. But winding roads are inevitable in highway construction. If the road curvature is not very large, the adjustment plate can be used for adjustment and installation. Generally, the length of the adjusting plate is 2m, 3m or 1m.

If the curvature is large, the installation can be carried out by mechanical pressure. In this way, after one end of the highway guardrail is fixed, the corrugated beam slab is forcibly bent to the upright post by machinery, and then the other end is fixed by bolts. Some users will tell suppliers about the number of bends in advance. The supplier will customize the curved road guardrail according to the radian provided by the customer. If it is a right-angle bend, you can use two-way ends for installation, which is simple (this method is suitable for installation of highway guardrail at the opening).

The Difference between Steel-plastic Composite Pipe and Steel-lined Pipe is Here(2021年09月29日)

tianchuangpipe — 2021-09-29T15:37:59+0900

https://www.tianchuangpipe.com/the-difference-between-steelplastic-composite-pipe-and-steellined-pipe-is-here.html

You may not be able to distinguish steel-plastic composite pipes and plastic-lined steel pipes. They do not know their respective properties or where they are used. In fact, the difference between steel-plastic composite pipes and plastic-lined steel pipes is quite big. You can't see that the main reason is that you don't know enough about these two kinds of pipes. Today's article will introduce the two kinds of pipes separately. After you have a general understanding of them, we will introduce the difference between the steel-plastic composite pipe and the plastic-lined steel in detail.

1. The characteristics of steel-plastic composite pipe

The basic materials of the steel-plastic composite pipe are seamless steel pipes and welded steel pipes, with certain strength and rigidity, which is incomparable with plastic pipes and aluminum-plastic pipes. In addition, its inner wall is very smooth, so no scaling occurs. The phenomenon, although it is steel, the overall weight is light, the key is impact resistance, and it will not shrink and expand due to changes in the environment, so the safety will be higher.

2. Characteristics of plastic-lined steel pipe

The plastic-lined steel pipe is based on galvanized seamless steel pipe and welded steel pipe. It is an upgraded version of galvanized pipe. It has a wide range of applications, good corrosion resistance and long service life, but the cost is high, and the connecting parts easily cause water pollution.

3. The difference between steel-plastic composite pipe and plastic-lined steel pipe

As an improved version of drinking water pipes, the two are not much different in mechanical strength, pressure-bearing performance and service life, and the advantages are also very similar, but after all, the two are two different pipes, so please distinguish carefully. There are still.

The steel plastic composite pipe is a five-layer composite pipe. The inner layer is non-toxic and pollution-free, but the main material of the inner layer of the plastic-lined steel pipe is epoxy resin powder or PE powder, which contains harmful ingredients. Long-term water supply will directly endanger human health.

The steel-plastic composite pipe is smooth and not easy to scale. It can be used not only in cold water, but also in hot water. However, the inner wall of the plastic-lined steel pipe is uneven and not smooth, which causes the accumulation of scale volume, which breeds bacteria. When used in a hot water system, it will be heated and expanded. Its outer wall has no anti-corrosion layer, so it is more likely to rust, thus affecting the life span.

The last key point is that the price of the steel-plastic composite pipe will be slightly more affordable. Because the workmanship of the plastic-lined steel pipe is complicated and exquisite, the overall price will be higher than that of the steel-plastic composite pipe.

The difference between the steel-plastic composite pipe and the plastic-lined steel pipe is compared from the very small aspects. In fact, both are high-quality drinking water pipes with excellent overall performance. As for the last one to choose as your own water supply, you need to think about the pipes yourself. Maybe the shortcomings in the eyes of others are not that bad in your own eyes, or they have not affected your life at all, so you might as well make your own ideas.

Ways to Improve Galvanized Steel Pipe Production Process to Save Energy and Reduce Consumption(2021年09月29日)

tianchuangpipe — 2021-09-29T15:36:52+0900

https://www.tianchuangpipe.com/ways-to-improve-galvanized-steel-pipe-production-process-to-save-energy-and-reduce-consumption.html

With the increasing maturity of steel pipe hot-dip galvanizing production technology and the improvement of process standardization, enterprises with the same capacity of one million tons have become commonplace. The fierce competition in the market focuses on brand to quality, benefiting price, and finally fighting on cost.

Looking at the actual hot-dip galvanized steel pipe production line, there are not many companies that are truly fully automated and intelligent. How to improve the steel pipe galvanizing production process to further achieve the purpose of energy saving, consumption reduction and efficiency increase?

1. Promote the development of pickling automation technology and equipment

For steel pipe galvanizing, the current process of pickling is indispensable. Therefore, it is difficult to control the operation of online employees, the working environment, and the quality of pickling. The development of a complete set of automated pickling technology and equipment is imminent. The original pickling line has the following problems:

Many manual operations. Workers standing by the acid tank are very dangerous. The steel pipes have a large swing in the transportation and manual liquid dispensing is not accurate.

Poor operating environment. The acid tank is open, with acid mist, and the operating room has high humidity.

Workers control the crane operation without accuracy.

Manual testing cannot feed back real-time data in time, affecting production.

In view of the above problems, the development can achieve cleaner production, save energy, and reduce labor intensity:

The crane is accurately positioned, walks stably, and workers are far away from operation, which solves the safety and labor intensity of personnel.

The crane can move up and down flexibly, reducing labor.

Adjustable control of process time meets the quality of pickling.

Online real-time detection, to achieve reasonable use of acid, automatic fluid replenishment, reduce testing time and human operation errors.

Ladder flow acid tank layout.

Online temperature control system.

Multiple circulation water saving system.

Automatic acid heating system.

Path optimization control system.

2. Improve the Zinc pot system

As a key equipment, how to extend the service life of the zinc pot and assume its due mission has become the focus of the industry.

(1) When the new zinc pot is installed and used, the zinc ingot is often not added first, and the furnace temperature is heated to about 600℃ for a certain period of time to eliminate the residual stress in the production.

(2) The depth of the zinc pot is popularized, effectively increasing the heating area of the zinc pot, reducing the heating intensity of the zinc pot, lowering the temperature of the inner wall of the zinc pot, increasing the workload, making it more conducive to the sedimentation of zinc dross and improving the surface quality of the plating parts.

(3) The heating method of the zinc ingot alleviates the sudden drop in the temperature of the zinc liquid and also prevents the danger of explosion.

(4) The overall shape of the zinc pot is changed to increase the recovery of the residual zinc blowing liquid inside and outside.

(5) Improve the internal and external blowing residual liquid recovery device twice.

What Should be Noted When Purchasing ERW Steel Pipe(2021年09月29日)

tianchuangpipe — 2021-09-29T15:36:07+0900

https://www.tianchuangpipe.com/what-should-be-noted-when-purchasing-erw-steel-pipe.html

ERW steel pipes are steel pipes whose welds are parallel to the longitudinal direction of the steel pipe. They are mainly used in water supply engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. Its application scale is wide, the production process is simple, the production efficiency is high, the cost is low, and the growth is rapid. So what do we need to pay attention to when purchasing ERW steel pipes?

1. The types of steel pipe

1) Divided by type: straight seam steel pipe, seamless steel pipe, spiral steel pipe, etc.

2) Classification of ERW steel pipe shape of straight seam steel pipe: square pipe, rectangular pipe, oval tube, flat oval tube, semicircular tube, etc

2. The quality test of ERW steel pipe

Ordinary straight seam pipes are implemented in GB/T3091-2015. If they are used as structures (columns and other types of applications), they can be competent. However, if it is used for processing (building roller bodies), pressure equipment (applied to boiler equipment, oil and gas pipelines), the requirements for the ovality, straightness and weld of the straight seam steel pipe are a bit low.

The requirements for processing ERW pipes are much higher than those for structural ERW pipes. ERW steel pipes for fluid transportation can be divided into ERW steel pipes for ordinary fluid transportation and ERW pipes for pressure (in fact, there are many types of fluid pipes, and they are only classified according to whether they are pressure-bearing)

A. The test standards of steel pipes for low-pressure fluid transportation can be implemented in accordance with GB/T3091-2015.

B. The production of pressure-bearing ERW pipes is subject to standards such as GB/T3087 or API or GB/T9711.2. These standards have high requirements.

Definition of Scaffolding Pipes:
A structural member used for the support of overhead laying pipeline on the ground is divided into fixed support, sliding support, guide support, rolling support, etc.

The pipe support can be used in any place where there is pipe laying, also known as pipe support, pipe part, etc. As the support structure of the pipeline, the scaffold pipeline supplier divides the pipe support into two types: fixed and movable ones according to the operation performance and layout requirements of the pipeline. The place where the fixed point is set becomes the fixed support. This kind of pipe support and the pipe bracket cannot have relative displacement. Moreover, the deformation of the fixed pipe support under force shall be smaller than the deformation value of the pipe compensator, because the pipe support should have sufficient rigidity. The movable pipe support is adopted at the place where the intermediate support is set, and the relative displacement between the pipe and the pipe support is allowed, without restricting the thermal deformation of the pipe.

Classification of Scaffolding Pipes
1. According to the load, it can be divided into three levels: extra light (Q), medium and extra heavy (Z). In each load level, there are four types of structure: axial sliding, bidirectional sliding, guide sliding and double-guide sliding.

2. According to the material of the support, it can be divided into steel structure, reinforced concrete structure, brick and wood structure.

3. According to the purpose, it can be divided into movable bracket (bracket that allows the pipe to be moved on the bracket) and fixed bracket (bracket that is used to fix the pipe). The fixed bracket is used where the axial displacement of the pipe is not allowed. The movable brackets are divided into sliding bracket, guide bracket and rolling bracket.

Since the fire-fighting pipeline is often in a static state, the requirements for the pipeline are relatively strict, and the pipeline needs to be pressure resistant, corrosion resistant, and high temperature resistant. We supply en 10255 steel pipe, steel fire sprinkler pipe, jis g3444 pipe, galvanized electrical pipe,etc.

Fire protection pipeline classification: ductile water supply cast iron pipe, hot-dip galvanized steel pipe, stainless steel pipe, alloy pipe and composite pipe, etc.

Fire protection pipeline installation process: Installation preparation → dry pipe installation → alarm valve installation → stand pipe installation → spraying layered dry branch pipe, fire hydrant and branch pipe installation → water flow indicator, fire water pump, high water tank, water pump coupler installation → pipeline pressure test → pipeline flushing → spray head branch pipe installation (system comprehensive pressure test and flushing) → throttle device installation → alarm valve fittings, fire hydrant fittings, sprinkler head installation → system water test adjustment

General requirements for the main points of fire protection pipeline connection technology:

(1) When the pipes of the fire hydrant water supply system adopt hot-dip galvanized steel pipes on the inner and outer walls, they should not be welded. When the system pipeline adopts non-corrosive inner wall pipeline, it can be connected by welding, but the pipeline welding should meet the relevant requirements. The pipes of the automatic sprinkler system (behind the alarm valve) cannot be welded, but threaded, grooved pipe joints or flange connections should be used.

(2)Galvanized steel pipe with pipe diameter > 100mm for fire hydrant water supply system shall be connected by flange or groove. Automatic sprinkler system pipe diameter > 100mm is not clear and cannot use threaded connection. It is only required that flange connections or groove connection points should be provided at a certain distance on pipe sections with pipe diameter ≥ 100mm.

(3) For fire hydrant water supply system and automatic sprinkler system pipes, threaded flanges are recommended when flanged connection is used, and secondary galvanizing is required when welding flanges are used.

(4)When any pipe section needs to change the pipe diameter, reducer pipe joints and pipe fittings that meet the standard should be used.

The reasons for the deformation of steel-plastic composite pipes are often complicated, but we only need to grasp the deformation rules, analyze the causes, and choose different methods to prevent the deformation of the mold, which can be reduced and controlled. Generally speaking, the following measures can be adopted to prevent the deformation of steel-plastic composite pipe by heat treatment.

(1) Reasonable selection of materials. For steel-plastic composite pipes, micro-deformed die steels with good raw materials (such as air-quenched steel) should be selected. For die steels with severe carbide segregation, reasonable casting and quenching and tempering heat treatment should be performed. Larger and uncastable die steels can be treated with solid solution double refinement heat treatment.

(2) The mold structure design should be reasonable, the thickness should not be too wide, the shape should be symmetrical, the deformation rules should be grasped for the larger deformation mold, and the processing allowance should be reserved. For the large, steel-plastic composite pipe, a combined structure can be selected.

(3) The S-P composite pipe should be pre-heated to eliminate the residual stress during the machining process.

(4) Reasonably select the heating temperature and control the heating speed. For the S-P composite pipe, slow heating, preheating and other balanced heating methods can be adopted to reduce the heat treatment deformation of the mold.

(5) On the premise of ensuring the hardness of the mold, try to use pre-cooling, staged cooling quenching or warm quenching process.

(6) For steel-plastic composite pipes, when conditions permit, try to use vacuum heating and quenching and cryogenic treatment after quenching.

(7) For some sophisticated molds, pre-heat treatment, aging heat treatment, and tempering and nitriding heat treatment can be used to control the accuracy of the mold.

(8) When repairing mold blisters, pores, wear and other shortcomings, use cold welders and other correction equipment with low thermal impact to avoid deformation during the repair process.

In addition, the correct heat treatment process operation of the spiral tube (such as hole plugging, tying hole, mechanical fixing, suitable heating method, correct selection of the cooling direction of the mold and the movement direction in the cooling medium) and the reasonable tempering heat treatment process are also the useful methods for steel-plastic composite pipe deformation.

Pay attention to the safety of gas pipeline installation when decorating the kitchen. However, the installation of gas stove pipelines is particularly troublesome. Failure to pay attention will cause safety accidents. Therefore, it is very necessary to understand the gas pipeline installation specifications clearly. What are the gas pipe installation steps? These are some basic safety knowledge.

Gas pipe installation specification

1. The pressure of the gas pipeline in the user's room and the rated pressure used by the gas burner of the gas equipment should comply with the national standards.

2. The application of pipelines, pipe fittings, pipeline accessories, valves and other materials to indoor gas pipelines shall comply with the requirements of the design documents. The pre-installation inspection shall be carried out in accordance with the current national standards, and the unqualified shall not be used.

3. The upstream construction project before the indoor gas pipeline installation should be able to meet the requirements of pipeline construction and installation.

4. When installing the gas pipeline, the prefabrication and installation of the pipeline should be carried out according to the design and construction drawings.

5. Pipes, fittings and pipe accessories used for gas pipelines, when the design documents do not clearly stipulate, the pipe diameter is less than 2 or equal to 50. It is good to use galvanized steel pipe or copper pipe.

6. The copper pipe should be made of TP2 pipe.

7. During the construction of gas pipelines, avoid the welding seam of the pipe body facing the wall. The pipelines with inconspicuous weld seams should be marked in advance.

8. Copper pipes or stainless steel corrugated pipes buried in the wall should be slotted with a special excavator. The groove width should be the outer diameter of the pipe plus 20mm, and the depth should meet the requirement that the covering thickness is not less than 10mm. It is strictly prohibited to dig pipe grooves in load-bearing walls, columns and beams.

Explanation of the Points of the Hot-dip Galvanized Green House Tube Installation(2021年)

The hot-dip galvanized green house tubes have a good plot, and the area where the greenhouse is built should be fertile soil. The temperature rises quickly, drainage and irrigation are convenient, the leeward wind is sunny, the altitude is flat, the water source is abundant, and it is close to the power source, and the transportation is convenient. Lay the foundation of the hot-dip galvanized greenhouse pipe. Before the equipment, the line should be laid out and trenched after the selected plot is measured. The trench should be dug straight and the bottom of the trench should be consolidated.

Put masonry under the arch to prevent the arch from sinking under the force. The 6mm diameter steel bar is tied to the bottom of each arch through the circular hole at the lower end of the arch, and then the trench soil is filled back. If possible, it is better to build the foundation with bricks in the trench.

What are the hot-dip greenhouse galvanized pipe equipment? For various components and fixtures, use wooden hammers or mallets for fixture equipment, install lightly, nail lightly, and over-tighten to avoid deformation of fixtures or damage to steel pipe galvanized thin. The equipment of various components should be assembled according to the plan, such as the distance of the arches, and the distance of the longitudinal rods.

For the hot-dip galvanized green house tube to cover the film, a spring slot should be set, and the plastic film should be fixed with a spring. The plastic film is first glued into a whole sheet and then covered with an orange. When installing, an old film can be placed in the card slot to protect the new film. Assuming that the plastic film is not spliced beforehand, the slot distance is 10cm smaller than the width of the film according to the original piece dividing device. The two films should be overlapped with each other, flattened and straightened, and the card slots are used together.

The laminating line for hot-dip galvanized greenhouse pipes must be installed even if there is a card slot, the same as usual every 1-1.2 meters, and the next one every half meter in the windy area, otherwise the film is still loose, bulging and damaged when in strong wind.
