weld pipe


The commonly used materials of welded pipes are :Q235A, Q235C, Q235B, 16Mn, 20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.The blank of welded steel pipe is steel plate or strip steel, which can be divided into furnace welded pipe, electric welded pipe (resistance welded pipe) and automatic arc welded pipe due to different welding processes


Welded pipe.Due to the different welding forms, it is divided into two types: straight welded pipe and spiral welded pipe.Because of its end shape is divided into circular welded pipe and shaped (square, flat, etc.) welded pipe.Welded pipes are divided into the following categories due to their different materials and USES: GB/ t3091-2001 (galvanized welded steel pipes for low-pressure fluid transport).Mainly used for water, gas, air, oil and heating hot water or steam, such as the general lower pressure fluid and other purposes.Its representative material is :Q235A grade steel.GB/ t14291-2006 (welded steel pipe for fluid transport in mines).It is mainly used for straight seam welding steel pipe for mine pressure wind, drainage and shaft gas discharge.Its representative material Q235A, B grade steel.Large diameter electric welded steel pipe for low pressure fluid transport.Mainly used for conveying low pressure fluid such as water, sewage, gas, air, heating steam and other USES.Its representative material is Q235A grade steel.GB/ t12770-2002 (welded stainless steel pipe for mechanical construction).Mainly used for machinery, automobile, bicycle, furniture, hotel and restaurant decoration and other mechanical parts and structures.Its representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.GB/ t12771-1991 (welded stainless steel pipe for fluid transport).Mainly used for conveying low pressure corrosive medium.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 building decoration (JG/T 3030-1995), large-diameter electric welded steel pipe for low-pressure fluid transportation (GB/T 3091-2001), and welded steel pipe for heat exchanger (yb4103-2000).
