Complete set of welded pipe manufacturing unit Thin-walled stainless steel pipe is the main raw material of bimetal composite pipe. Due to non-standard size or capacity, the cost of purchasing steel pipes is very high. The complete set of welded pipe manufacturing unit produced by our company haslow cost, convenient operation and maintenance cost. low.

The complete set of welded pipe manufacturing units produced by our company includes: uncoiling machine, leveling machine, transverse shearing machine, longitudinal shearing machine, bending machine, welding forming machine, etc.

Common materials for welded pipes are: Q235A, Q235C, Q235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

The blanks used for welding steel pipes are steel plates or strip steels, which are divided into furnace welded pipes, electric welded (resistance welded) pipes and automatic arc welded pipes due to their different welding processes. There are two types of welded pipe: straight seam welded pipe and spiral welded pipe. Because of its end shape, it is divided into round welded pipes and special-shaped (square, flat, etc.) welded pipes. Welded pipes are divided into the following varieties due to their different materials and uses:

GB / T3091-2008 (welded steel pipe for low-pressure fluid transport): It is mainly used to transport water, gas, air, oil, and generally lower pressure fluids such as heating hot water or steam and other purposes. Its representative material is: Q235A grade steel.

GB / T14291-2006 (Mining fluid conveying welded steel pipe): It is mainly used for straight seam welded steel pipe for mine pressure, drainage and shaft gas discharge. It represents the material Q235A, B grade steel.

GB / T12770-2002 (stainless steel welded steel pipes for mechanical structures): mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts.Its representative materials are 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.

GB / T12771-1991 (stainless steel welded steel pipe for fluid transportation): It is mainly used to transport low-pressure corrosive media. Representative materials are 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2 and so on.
