Stainless Steel Seamless Pipe
Stainless Steel Seamless PipeStainless steel seamless pipe, also known as stainless steel seamless tube, is a long hollow cylinder used for moving fluids (liquids or gases). "Stainless seamless pipe" and "stainless steel tube" are almost interchangeable, although minor distinctions exist-generally, a tube has tighter engineering requirements than a pipe. Jiangsu Sheye Metal is a professional manufacturer specialized in manufacturing stainless steel seamless pipes in large, medium, and small diameters. Various steel grades stainless steel seamless pipes are produced with complete specifications and supreme quality. Sheye Metal has fine equipment and complete quality management, establishes modern quality management system, introduces internationally advanced technology and adopts international advanced production technique. Seamless stainless steel pipes are widely used in such industries as petroleum, chemical industry, machinery, electric power, chemical fiber, papermaking, printing and dyeing, food and pneumatic parts etc. The company is provided with complete inspection equipment and adopts technical standards for products such as: stainless steel seamless pipe for fluid transportation, stainless steel seamless pipe for construction, stainless steel seamless for boiler and heat exchanger. The outside diameter of seamless stainless we produce ranges from 4.0mm to 1219mm. The wall thickness is 0.5mm to 100mm. For metal, we are serious.Specification of Stainless Steel Seamless Pipe Size OD: 4.0 ~ 1219mm; WT: 0.5 ~ 100mm; Length: 6m, 12m, Max.18mProcess Seamless, Cold Drawn, Cold Rolled, Hot RolledEnd PE(Plain End), BE(Beveled End), NPT, BW(Butt Weld End)Surface Aid Pickling, Polishing(180#, 220#, 240#, 320#, 400#, 600#)Theoretical Weight(kg/m) Weight/meter = (OD-WT)*WT*0.02507 Both OD and WT in mm.Note: OD is the specified outside diameter.WT is the specified wall thicknessStainless steel pipes shall be pickled free of scale.
