Because the inner and outer walls of precision steel tubes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, they are mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless tubes, but also welded tubes. Precision steel pipe with high dimensional precision, inner and outer surface smoothness, after heat treatment, there is no oxide film on the inner and outer surface of the steel pipe, the steel pipe flaring, flattening without crack, cold bending without deformation, and can withstand high pressure, can make various complicated deformation and mechanical deep processing.

Precision steel tubes are used in automobile, motorcycle, electric car, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, middle and low pressure boiler seamless steel tubes and other categories, can also be used in steel bars, bearings, hydraulic, mechanical processing and other fields! The production process of precision steel pipe is the same as that of ordinary seamless pipe, which is more than the process of pickling and cold rolling. Precision steel tube process billet -- inspection -- peeling -- inspection -- heating -- perforation -- pickling passivation -- grinding -- lubrication -- air drying -- cold rolling -- oiling -- cutting -- inspection -- identification -- finished product packaging steel tube difference 1, seamless steel tube is the main feature of no welding joint, can withstand greater pressure. The product may be very rough cast or cold - drawn. 2. Precision steel pipe is a product emerging in recent years, mainly with strict tolerance and roughness of inner hole and outer wall size.
