Information

The manufacturer of DIN 2391 cold draw pipe tells you that the so-called cold drawing is to use a cold drawing machine for metal construction without heating. The manufacturer of DIN 2391 cold draw pipe tells you that the advantage is that it does not need to be carried out at high temperature, and the disadvantage is residual stress. Larger, and can not be drawn too long, cold drawing can improve the toughness and tensile strength and obtain better mechanical properties.

customized DIN 2391 cold draw pipe products
DIN 2391 cold draw pipe manufacturer tells you the cold drawn (rolled) seamless steel pipe process: round tube billet → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) →Blank tube → heat treatment → straightening → hydraulic test (flaw detection) → marking → warehousing.
The difference between cold drawn and cold drawn:
DIN 2391 cold draw pipe manufacturers tell you that cold drawing and cold drawing are two different methods of metal cold processing, and they are not the same concept. Cold drawing refers to the method of applying tensile force on both ends of a metal material to cause the material to be stretched and deformed; DIN 2391 cold draw pipe manufacturers tell you that cold drawing refers to applying a drawing force on one end of the material to pull the material out through a mold hole The method, the hole diameter of the mold should be smaller than the diameter of the material. The cold drawing process causes the material to have extrusion deformation in addition to the stretching deformation. The cold drawing process is generally carried out on a special cold drawing machine. The manufacturer of DIN 2391 cold draw pipe tells you that the material processed by cold drawing has better performance than the material processed by cold drawing.
