Characteristics of Finished Steel Pipe:

1. Cold-rolled precision steel pipe has high tolerance dimension accuracy, product precision is controlled at (+0.5mm), good inner and outer surface finish, and no oxide layer on the surface.
2. Precision cold-rolled steel pipe has excellent comprehensive performance, can withstand high pressure, cold bending, flattening, no cracking, no wrinkle, and can do all kinds of complex deformation and mechanical processing.

Quenching and tempering can change mechanical properties

Elongation

Precision steel pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc. They can also be applied to steel sleeves, bearings, hydraulic, mechanical processing and other fields!

Precision seamless steel pipe

Precision steel pipe is a kind of high-precision steel pipe material after cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The cylinder can be a seamless tube or a welded tube.

Hot-rolled seamless steel pipes

Hot-rolled steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes, etc.

Shaped seamless steel tube

Shaped seamless steel tubes are widely used in a variety of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe generally has a large moment of inertia and a section modulus, and has a large bending and torsion resistance, which can greatly reduce the structural weight and save steel.
