Welded stainless steel rectangle pipe mainly falls into two categories: straight-seam SS welded pipe and spiral SS welded pipe. Wisine produce both seamless and welded stainless steel rectangle pipe, available in multiple size and various grades as per ASTM, JIS, EN, DIN and GOST standards. The main grades of stainless steel rectangle pipe we produce are 304(L), 316(L), 321. Customization, whether in terms of grade or dimension, is acceptable so long as the quantity meets our MOQ requirement (1 Ton per size). Our stainless steel rectangle pipe is extensively used for conveying fluid medium, like oil and gas, water, steam etc. Due to its relatively lighter weight under the same bending strength and torsional strength, stainless steel rectangle tubes are also widely used in the production of machine parts and engineering structure.
