Related equipment performance capabilities of welded steel pipe

Longitudinal welded steel pipe depending on the welding process is generally divided into two types:. ERW steel pipe and LSAW steel pipe. According to different forming ways, LSAW steel pipe can be divided into: UOE steel pipe, JCOE welded pipe and HME steel pipe.
