Our company specializes in the production of sanitary stainless steel welded pipes and pipe fittings. We operate a complete welded pipe assembly line including cage forming, multi-shade welding, internal and external welding, and mirror polishing.

We strictly adhere to Chinese GB, ASTM, JIS, and DIN standards, with quality control managed through ISO9001 certification. Our products undergo eddy current testing, water pressure testing, process performance inspection, intergranular corrosion testing, and metallographic inspection.

Compared to stainless steel seamless cold drawing and cold tie processes, our products offer stable quality, uniform wall thickness, high precision, no strain or pitting holes, excellent surface quality, low hardness, and direct production of elbows, tees, and related accessories.

Our products are widely used in food processing, medical machinery, petroleum, chemical industries, and related applications.
