BACKPrecision seamless steel pipe
Fine drawing tube
Description:The difference between cold drawing and cold drawing: cold drawing and cold drawing are two different methods of cold metal processing, the two are not the same concept. Cold drawing refers to the method of applying tension at both ends of a metal material to make the material produce tensile deformation; Cold drawing refers to the drawing force applied at one end of the material, so that the material is pulled out through a mold hole, the mold aperture is smaller than the diameter of the material. Cold drawing process makes the material not only have tensile deformation but also extrusion deformation. Cold drawing process is generally carried out on a special cold drawing machine. Materials processed by cold drawing have better properties than those processed by cold drawing. Main applications: automobile, motorcycle, refrigeration equipment, hydraulic parts, pneumatic cylinder, and other steel pipe precision, finish, cleanliness, mechanical properties have high requirements for customers.
parameters
So products that are primarily used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless tubes,
The main production of steel pipe brands: 10#, 20#, 35#, 45#, 40cr, 42crmo, 16mn, etc
introduction
The characteristics of fine rolled pipe: (1) cold rolled precision steel pipe tolerance size accuracy is high, the product accuracy is controlled within ±0.05mm, the internal and external wall finish is good, the surface no oxide layer. (2) The comprehensive performance of cold-rolled precision steel pipe is excellent, can withstand high pressure, cold bending, flaring, flattening no cracking, no wrinkle skin, can do a variety of complex deformation and mechanical processing. (3) The popularization and application of precision seamless tube can save steel, improve processing efficiency, reduce processing procedures and equipment investment, save costs and greatly save machining hours, improve production and material utilization, and help improve product quality and reduce costs. Application: Cold-rolled precision steel pipe is widely used in automobile, motorcycle, electric vehicle, pneumatic cylinder, petrochemical, electric power, Marine, aerospace, bearing, pneumatic components, medium and low pressure boiler and other fields.
