Company Overview
Our company specializes in the production of sanitary stainless steel welded pipes and pipe fittings. We operate complete welded pipe assembly lines including cage forming, multi-shade welding, internal and external welding, and mirror polishing. Our manufacturing strictly follows Chinese GB, ASTM, JIS, and DIN standards with ISO9001 quality system certification. Products undergo eddy current testing, water pressure testing, process performance inspection, intergranular corrosion, and metallographic inspection. Compared to stainless steel seamless cold drawing, 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, medical machinery, petroleum, chemical, and related industries.
