Commonly used materials for welded pipes are: Q235A, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc. The billet used for welded steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc because of different welding processes.
welded pipe
Welded pipe. Due to the different welding forms, it is divided into two types: straight seam welded pipe and spiral welded pipe. Because of its end shape, it is divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe. Welded pipes are divided into the following varieties due to their different materials and uses: GB/T3091-2001 (galvanized welded steel pipe for low pressure fluid transportation). Mainly used for conveying general lower pressure fluids such as water, gas, air, oil and heating hot water or steam and other purpose pipes. Its representative material is: Q235A grade steel. GB/T14291-2006 (Welded steel pipe for mining fluid transportation). It is mainly used for straight seam welded steel pipes for mine air pressure, drainage and shaft discharge gas. It represents the material Q235A, B grade steel. GB/T14980-1994 (large diameter electric welded steel pipe for low pressure fluid transportation). Mainly used for conveying low pressure fluids such as water, sewage, gas, air, heating steam and other purposes. It represents the material 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. GB/T12771-1991 (stainless steel welded steel pipe for fluid transportation). Mainly used for conveying low pressure corrosive medium. The representative materials are 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc. We can offer Stainless Steel Pipe products, including Stainless Steel Capillary Pipe, Stainless Steel Precision Pipe, Stainless Steel Seamless Pipe , Stainless Steel Sanitary Pipe , Thick Wall Stainless Steel Pipe, Stainless Steel Bright Tube , Stainless Steel Needle Tube , Stainless Steel Fine Tube , Stainless Steel Coil , Welded Stainless Steel Pipe , Stainless Steel Industrial Pipe, Stainless Steel Round Tube , Medical Stainless Steel Tube , Stainless Steel Thin Wall Tube , Stainless Steel Shaped Tube , Stainless Steel Elbow , Stainless Steel Snake Bone Tube, Stainless Steel Decorative Tube, Stainless Steel Electronic Cigarette Tube, Stainless Steel Tube Processing, Copper Pipe , Titanium Alloy Tube , Aluminum Tube , and so on.
