Description

LSAW Steel Pipe

Short for submerged arc welding longitudinal,SAWL steel pipe is made of hot rolled steel plate by JCOE and UOE.
JCOE means the forming process, that is, J shape, C shape, O forming, insider&outside welding and cold expansion after welding.
Other name: LSAW steel pipe, DSAW steel pipe, straight seam welding pipe, longitudinal submerged welding pipe, EFW steel pipe
