API 5L GR.B Carbon Spiral Welded SSAW Steel Pipe

API 5L GR.B Carbon Spiral Welded SSAW Steel Pipe

Spiral welded pipe: It is made by rolling a low carbon carbon structural steel or a low alloy structural steel strip into a tube blank at a certain angle of a helix (called a forming angle), and then welding the pipe seam, which can be used in a narrower manner. Strip steel for the production of large diameter steel pipes.

QualityManagement

We have always been inspecting and monitoring the quality through process at control points and conducting strict inspections at every step, resulting to its high-quality products in line with world standards and customers request.

raw material inspection: dimension and tolerance check, appearance quality check, mechanical properties testing, weight check and raw materials quality assurance certificate check

semi-finished goods inspection: physical and chemical inspection, leakage magnetism and ultrasonic inspection

finished goods inspection: dimension and tolerance, appearance quality check and mechanical properties testing

inspection before ex-factory: We arrange our QC staff to manufacture’s plant for final quality and packing inspection each time before we deliver goods to port for shipping, and the connected sales staff will be with QC staff to make sure we did everything fully and strictly meet customer’s requirements.
