PSL1 LSAW Steel Pipe
PSL1 LSAW Steel Pipe
LSAW steel pipe is short for longitudinal double submerge arc welding steel pipe was made of steel plates of hot rolled by JCOE.
JCOE means the forming process, as J shape forming, inner outside welding and cold expansion after welding.
Feature: Large diameter, thick wall, pressure pipeline
Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength,
Yield strength, Elongation), Technical Properties (Flattening Test, Blow Test, Impact
