Finish rolled pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment

Release time: September 12, 2020 popularity: one

Finishing tube It is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. Due to the advantages of no oxide layer on the inner and outer wall, no leakage under high pressure, high finish, no deformation in cold bending, no crack in flaring and flattening, it is mainly used to produce pneumatic or hydraulic pressure Component products, such as cylinders or cylinders, can be seamless or welded.

Product model

After heat treatment, there is no oxide film on the inside and outside surface of the tube. The tube has no crack when it is flared and flattened. It can bear high pressure, and can be used for various complex deformation and mechanical deep processing.

Main production steel pipe brand: 10, 20, 35, 45, 40Cr, 42CrMo, 16Mn, etc

20 ා finish rolling pipe, also known as cold rolling precision steel pipe, is a kind of production process of seamless steel pipe.

20 ා the weight calculation formula of finish rolling pipe: [(outer diameter wall thickness) * wall thickness] * 0.02466 = kg / M (weight per meter).

Cold drawing is to use cold drawing machine to draw metal pipe without heating. The advantage is that it does not need to be carried out at high temperature. The disadvantage is that the residual stress is large and cannot be drawn too long. Cold drawing can improve toughness and tensile strength and obtain better mechanical properties.

Cold drawing refers to the method of exerting tension on both ends of metal material to make the material produce tensile deformation; Cold drawing refers to the method of drawing material through a die hole by exerting a pulling force at one end of the material. The diameter of the die is smaller than the diameter of the material. In addition to tensile deformation, there is also extrusion deformation in the finishing tube processing. The cold drawing process is generally carried out on a special cold drawing machine. The properties of materials processed by cold drawing are better than those processed by cold drawing.
