Stainless Steel Welded Pipe
Our stainless steel straight welded tubes are made of premium 304, 316L and 2205 duplex steel, produced by automatic TIG & plasma welding for smooth, compact welds free of pores and cracks. All pipes pass NDT, hydrostatic and air tightness tests to meet GB and ASTM standards.
High dimensional accuracy with mirror, brushed and internal polished finishes. Anti-acid, alkali, salt spray and high temperature. Smooth inner walls avoid dirt accumulation, clean and non-precipitating with high strength. Widely used in chemical fluid, water purification, marine engineering and architectural decoration. Custom sizes and full inspection certificates available.
Sanitary stainless steel welded pipe
Sanitary stainless steel welded pipes are made of high-purity 304 / 316L stainless steel. Adopting automatic TIG and plasma precision welding technology, the welds are uniform, dense and defect-free.
With internal and external mirror polishing, degreasing, pickling and sterile passivation treatment, the pipes feature ultra-smooth inner surface, no dirt accumulation, no bacteria growth and no metal precipitation.
All products pass hydrostatic test and NDT inspection, fully compliant with sanitary standards for food, beverage, pharmaceutical and pure water systems. Custom sizes are available.
Stainless steel welded square tube
Stainless steel welded square tubes are made of high-quality 304, 316L and 2205 stainless steel. Adopting automatic TIG and plasma precision welding, the tubes feature straight shape, standard angles and smooth dense welds without pores or deformation.
With precise shaping and fine surface grinding, the tubes have high dimensional accuracy, stable structure and strong load-bearing capacity. Excellent corrosion resistance and oxidation resistance ensure long service life.
Widely used in architectural decoration, curtain wall frames, municipal guardrails, steel structures and equipment frames. Custom sizes and full inspection certificates are available.
