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

DSAW Steel Pipe
DSAW Steel Pipe
The double-sided submerged arc welded pipe is mainly rolled with hot rolled coils and medium plates. The double-sided LSAW steel pipe adopts double-sided submerged arc welding technology, and its wall thickness is relatively thicker than that of ordinary welded pipe. Compared to ordinary wall thickness welded pipes, the advantages are: high compressive strength, high impact strength, high performance, and long service life.
SAWL Steel Pipe
SAWL steel pipe Process flow:
1) Plate detection: The whole plate ultrasonic inspection shall be carried out before the steel plate used to manufacture large diameter straight seam Submerged arc welding steel pipe enters the production line.
2) Edge milling: Double sided milling is performed on the two edges of the steel plate using an edge milling machine to achieve the required plate width, edge parallelism, and beveling shape;
3) Pre bending edge: Use a pre bending machine to pre ben
Over the years’ experience, we insist on the quality as the base, carried out strictly in accordance with the corresponding standards from the raw materials procurement, plate detection, and processing production to finished LSAW steel pipes inspection and storage.
