Precision pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Because the inner and outer wall of the precision steel tube are free from oxide layer, and are not subject to high pressure without leakage, high precision, high finish, cold deformation, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components such as cylinder or Cylinder, can be seamless, but also welded pipe.

 

High precision high precision steel pipe, the inner and outer surface of the pipe finish, the inner and outer surface of the pipe after heat treatment without oxide film, pipe flares, flattening without cracks, cold deformation, and can withstand high pressure, can make a variety of complex deformation and mechanical processing deal with.

 

Basic purpose

Precision steel pipe is widely used in the fields of automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, medium and low pressure boiler seamless steel pipe and so on, but also applicable to the steel sleeve, bearings, hydraulic, machining, etc. field!

 

Precision steel pipe production process and ordinary seamless pipe, is more than the last road cold pickling process.
