FAQ

How do you ensure weld seam quality for longitudinal welded pipes?

We perform 100% hydrostatic testing on every pipe. For LSAW pipes, we also conduct 100% ultrasonic testing (UT) and X-ray (RT) on the weld seam. For ERW pipes, online eddy current or ultrasonic testing is applied. Third-party inspection (SGS, BV) is available.

Can you supply pipes with anti-corrosion coating?

Yes. We offer 3PE, FBE, galvanized, or black paint coating. Coating type and thickness can be customized based on your service environment (underground, offshore, or industrial).

What is the difference between ERW and LSAW pipes?

ERW pipes are made from steel coil with high-frequency welding, suitable for small to medium diameters (21.3–610mm) and thin walls. LSAW pipes are made from steel plate with submerged arc welding, suitable for large diameters (406–1422mm) and thick walls, offering higher pressure capacity and better weld integrity.
