Application

Stainless steel pipe (tube) has excellent characteristics of corrosion resistance and smooth finishing. Stainless steel pipe (tube) is commonly used in demanding equipment like automobiles, food processing, water treatment facilities, oil and gas processing, refinery and petrochemicals, breweries and energy industries.

Do you support third-party inspection?2026-06-14T12:45:46+00:00

Yes, we support third-party inspection by SGS, BV, TUV, Intertek etc., and whole-process supervision of production is available.

What’s the difference between seamless pipe and welded pipe?2026-06-14T12:43:05+00:00

Seamless pipe has no welding seam, featuring higher pressure bearing capacity, stronger corrosion resistance and higher dimensional accuracy, which is suitable for high-pressure/high-temperature/corrosive working conditions (such as petroleum, chemical industry, boiler). Welded pipe has a welding seam with lower cost, suitable for low-pressure fluid transmission.

What quality certificates can you provide?2026-06-14T12:45:08+00:00

We can provide MTC (Mill Test Certificate EN 10204 3.1/3.2), Chemical Composition Report, Mechanical Property Report, Non-destructive Testing (UT/ET/RT), Hydro-static Test, ISO 9001, PED, CE.
