A Study of Metallurgical Factors for Defect Formation in

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. API 5L EFW / ERW Carbon Steel Pipe, API 5L Lsaw /Hsaw In API 5L LSAW pipes, the welding is longitudinal, which signifies that steel is rolled into a pipe and the seam is welded longitudinally. However, in API 5L HSAW Pipes, steel coils are welded spirally, like a helix, so that the coil (strip) presumes the form of a pipe.
