 The blank used is steel plate or strip steel, which can be divided into furnace welding pipe, electric welding (resistance welding) pipe and active arc welding pipe due to different welding processes. Because of its different welding forms, it can be divided into straight welded pipe and spiral welded pipe. Because of its end shape, it can be divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe. Welded pipe is divided into the following varieties due to different materials and uses:



 

GB / t3092-1993 (galvanized welded steel pipe for low pressure fluid transportation). It is mainly used to transport water, gas, air, oil, heating hot water or steam and other general lower pressure fluid and other pipes. Its representative raw material is: Q235 grade a steel.



GB / t14291-1992 (welded steel pipe for mining fluid transportation). It is mainly used for the straight seam welded steel pipe for mine air pressure, drainage and axial gas drainage. It represents Q235A and B grade steel. GB / t14980-1994 (large diameter welded steel pipe for low pressure fluid transportation). It is mainly used to transport water, sewage, gas, air, heating steam and other low-pressure fluids and other uses. It represents Q235A grade steel.




GB / t12770-1991 (stainless steel welded steel tubes for mechanical structures). Mainly used in machinery, cars, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. Its representative raw materials are 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, etc.



GB / t12771-1991 (stainless steel welded steel pipe for fluid transportation). It is mainly used to transport low-pressure corrosive medium. The representative raw materials are 0Cr13, 0Cr19Ni9, 00cr19ni11, 00Cr17, 0cr18ni11nb, 0017cr17ni14mo2, etc.
