Welded pipe commonly used materials are: Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb etc..

The billet of welded steel is sheet or strip. It can be divided into the furnace pipe, welding (ERW) pipe and automatic arc welding pipe because of the difference of welding technologies. Because of the different forms of welding, it is divided into straight seam welded pipe and spiral welded pipe. And it is also divided into circular welded pipe and profiled (square, flat) welded pipe because of the ending shapes. Welded pipe can be divided into the following categories according to the different material and applications:

GB/T3091-2001 (galvanized welded steel pipe for delivering low pressure fluid). It is mainly used for the conveying of generally low pressure flow, such as water, gas, air, oil and heating hot water or steam and other purposes.Italy The representative material is Q235A grade steel.

GB/T3091-1993 (galvanized welded steel pipe for delivering low pressure fluid). It is mainly used for the conveying of generally low pressure flow, such as water, gas, air, oil and heating hot water or steam and other purposes. The representative material is Q235 grade steel.

GB/T3092-1993 (galvanized welded steel pipe for delivering low pressure fluid). It is mainly used for the conveying of generally low pressure flow, such as water, gas, air, oil and heating hot water or steam and other purposes. The representative material is Q235 grade steel.

GB/T14291-1992 (welded steel pipe for delivering fluid in mine industry). oil and gas pipeline It is mainly used in straight seam welded steel pipe, such as mine air pressure, drainage and shaft gas. The representative material is Q235A, B grade steel.

GB/T14980-1994 (welded steel pipe with a large diameter for the delivering of low pressure fluid). It is mainly used for conveying low-pressure fluid, such as water, sewage, gas, air and steam heating and other purposes. The representative material is Q235 grade steel.

GB/T12770-1991 (welded stainless steel pipe for mechanical structure). It is mainly used in machinery, automobile, bicycle, hotels, hotel furniture, decoration and other mechanical components and structural parts. thermal expansion pipe The representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb etc...

GB/T12771-1991 (welded stainless steel pipes for delivering liquid). It is mainly used to transport corrosive medium voltage. The representative materials are 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2 etc...

In addition, welded stainless steel pipe for decoration (GB/T 18705-2002), welded stainless steel pipe for architectural decoration (JG/T 3030-1995), and welded steel pipe with large diameter for delivering low pressure fluid (GB/T 3091-2001) and heat exchanger welded steel pipe (YB4103-2000).
