Longitudinal double submerge arc welding steel pipe(LSAW steel pipe) is made of steel plates of hot rolled by JCOE. JCOE means the forming process,as J shape,C shape,O forming,inner&outside welding and cold expansion after welding.It only has one straight seam on the pipe body.
1. Feature: Large diameter,thick wall,high pressure&low temperature resistance
2. Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength,Yield strength, Elongation), Technical Properties (Flattening Test,Blow Test, Impact Test,DWT test),Exterior Size Inspection, Hydrostatic Test, X-ray Test,UT test.
3. Application: The base metal and weld metal were tested according to the pipe specification EN 10224-2003, Widely used for liquid delivery,such as oil,gas,water and seashore,ground constructions.
