thick wall 8inch SCHXXS seamless steel pipe


Seamless steel pipes, a large number of used pipes conveying fluids, such as transport oil, natural gas, gas, water pipes and some solid materials, and so on. Compared to other steel and solid steel bar, the same torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle rack and construction using steel scaffolding ring with steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material, gun barrels to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. As in the perimeter of equal conditions, the largest area of a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of the pipe is pipe.
