A Study of Metallurgical Factors for Defect Formation in erw square welding steel pipe d

May 12, 2015 · A critical assessment has been made for the electric resistance welded API-J55 and P110 steel pipes to clarify the metallurgical factors crucial to the occurrence of welding defects. Electric resistance welding (ERW) is widely accepted due to its low cost and high efficiency of production as a conventional manufacturing technology for the steel pipes. However, ERW pipes are vulnerable to API 5L ERW LINE PIPE - UNIASENApr 29, 2019 · API 5L is specification for line pipe, newest edition is forty-five with effective date JULY 1,2013. This standard specifies requirements for the manufacture of two product specification levels (PSL 1and PSL 2) of seamless and welded steel pipes for use of pipeline transportation systems in the petroleum and natural gas industries. ERW steel pipe is []
