Stainless Steel Pipes & Tubes
Large Diameter Stainless Steel Welded Pipe
This product is TP304/316L stainless steel large-diameter welded pipes. The picture shows industrial-grade large-diameter tubes suitable for outdoor, large-scale infrastructure and industrial fluid transportation scenarios. Made of high-quality steel strips via high-frequency welding or argon-arc welding processes, it features high dimensional accuracy, combining the corrosion resistance of stainless steel with the high-flow delivery advantage of large diameters. Conventional specifications cover diameters from DN200 (8") to DN2000 (80"), with wall thicknesses from 6mm to 50mm, and a fixed length of 6m/12m (non-standard customization available).
This product is TP304/316L stainless steel seamless pipe / precision tube. The picture shows industrial-grade seamless tubes marked with ASTM A213 TP304L/TP310S. Produced from solid billets through piercing, hot rolling and cold drawing processes, it has no welds, excellent sealing performance and high dimensional accuracy. It is the preferred pipe for petroleum refining, aerospace, precision instruments and high-end fluid equipment. Conventional specifications cover diameters from 6mm to 630mm, with wall thicknesses from 1mm to 50mm, supporting multi-material customization.
Stainless Steel Rectangular Tube
This product is TP304/316L stainless steel square pipe / rectangular tube. The picture shows large-sized stainless steel square pipe blanks. It is available in two types: seamless square pipe and welded square pipe, manufactured by extruding round pipes or bending and welding steel plates. With its square cross-section offering excellent bending rigidity and stacking stability, it is the mainstream profile for building structures, mechanical frames and decorative engineering. Conventional specifications cover 10mm×10mm ~ 500mm×500mm (rectangular tubes: 10×20mm ~ 500×300mm), with wall thicknesses from 1.5mm to 20mm, standard length of 6 meters, supporting non-standard customization and special material requirements.
