A butt welding cap is a type of pipe fitting that covers the end of a pipe. It can be welded on to close the end of the pipe. On a weld, if it is a temporary close, or the contractor wants to add to the piping system in the future, he or she should allow additional pipe before closing so the pipe cap can be cut off and the pipe system extended as needed. This way you will not have less pipe than you need and the new fitting can be attached correctly.

Cap Vanish Paint Seamless Buttweld FAQ
1. What is the Function of Butt Weld End Cap?


SCH5, SCH10, SCH20, SCH40, SCH80, etc. represent different wall thicknesses. The specific wall thickness value can refer to ANSI B36.10, ANSI B36.19 American standard steel pipe standards.

Back in 2003, a small workshop was built upon the farming land in the rural area of Hebei Province, with only 20 workers and a few second-hand machines. In the last 18 years, Hebei Leading has become a group company including one butterfly valves factory and one flange factory, occupying over 700,000 square feet, with over 300 experienced workers and over 50 managements and sales. It is really a long way, but through hard work and always aiming high, we become a big piping manufacturer and service supplier in the north of China, with over 20million U.S. dollars turnover annually.
