Product Description

LSAW Pile Steel Carbon Pipes Psl1 Psl2 X65 X70 X42 S275jr S355jr S355j0h S355j2h
Product Description:
LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated  is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diater.  In the construction of high strength, high toughness and high quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick wall straight seam submerged arc welded pipes.   

According to API standards, in large oil and gas pipelines, straight seam submerged arc welding pipe is the only designated applicable pipe type when it passes through class 1 and class 2
areas such as alpine zone, seabed and densely populated urban areas. 
 According to the forming way, it can be divided into:  

UOE welded pipe: sheet steel plate at the edge of pre-bending, after U forming, O forming, internal welding, external welding, mechanical cold expanding process; 

JCOE welded pipe: namely according to the "J-C-O-E" pre-welding, forming, after welding through cold expanding and other processes;  

HME welded pipe: it is formed by mandrel rolling method according to "C-C-O", after welding, it goes through cold expanding and other processes
