Welded steel pipe used in billet steel sheet or strip steel, the welding process is divided into the stove pipe, welding (resistance welding) pipe and automatic arc welded pipe
Pipe. Because of its divided into Longitudinal and spiral welded pipe two. Because of the shape of the end into the pipe of circular welded pipe and shaped (square, flat, etc.). Pipe because of its material and for different purposes, divided into the following number of varieties: GB/T3091-2001 (low pressure fluid galvanized welded steel pipe). Mainly used for conveying water, gas, air, oil, and heating hot water or steam and other generally low pressure fluid, and other uses tube.
The representative of material: Q235A grade steel. GB/T14291-2006 (mine liquid welded steel pipe). Mainly used for mine air pressure, drainage, and the shaft to put gas straight seam welded steel pipe. Representative of material Q235A, B grade steel. GB/T14980-1994 (low pressure fluid with a large diameter welded steel pipe). Low-pressure fluid for conveying water, sewage, gas, air, heating steam and other purposes. The representative of material Q235A grade steel. GB/T12770-2002 (mechanical structure Welded stainless steel). Mainly used for machinery, automobiles, bicycles, furniture, hotels and hotel decoration, and other mechanical components and structural parts
