Because the stainless steel industrial pipe has good corrosion resistance, it can maintain the integrity of the engineering design of the structural components. Chromium-containing stainless steel also combines mechanical strength and high extensibility, is easy to manufacture, and can meet the needs of architects and structural designers. Therefore, stainless steel industrial pipes have been widely used in various industries, so stainless steel welded pipes are different due to their different materials.
GB/T3091-2001 (galvanized welded steel pipe for low pressure fluid transportation). Mainly used to transport water, gas, air, oil, heating water or steam and other generally lower pressure fluids and other purposes. Its representative material is: Q235A grade steel.
GB/T14291-2006 (Welded steel pipe for mining fluid transportation). Mainly used for straight seam stainless steel welded pipes for mine pressure, drainage and shaft gas discharge. Its representative material is Q235A, Grade B steel.
GB/T14980-1994 (Large diameter electric welded steel pipe for low pressure fluid transportation). It is mainly used to transport low-pressure fluids such as water, sewage, gas, air, heating steam and other purposes. Its representative material is Q235A grade steel.
GB/T12770-2002 (stainless steel welded steel pipe for mechanical structure). Mainly used in machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts. Its representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.
