Precision steel tube is a high-precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or The oil cylinder can be a seamless tube or a welded tube.
Application
The internal and external diameter can be controlled within +/- 0.01 mm. While guaranteeing anti-bending strength and torque strength, the weight of precision pipes is lighter. They can be widely used in manufacturing precision machinery parts and engineering structures, and are also commonly used to produce various kinds of conventional weapons, barrels, shells, bearings, and so on.
Specification
Precision steel pipe size tolerances
For hot-rolled precision steel pipes, the OD tolerance is +/- 0.1%.
For cold-drawn precision pipes, the following tolerances are allowed:
Diameters 6mm to 10mm, normal tolerance condition +/-0.2%, premium tolerance condition +/-0.15%.
10mm to 30mm, normal tolerance condition +/-0.4%, premium tolerance condition +/-0.2%.
30mm to 50mm, normal tolerance condition +/- 0.45%, premium tolerance condition +/- 0.3%.
For outer diameters above 50mm, normal tolerance condition +/- 0.1%, premium tolerance condition +/- 0.8%.
