Precision pipe is a high-precision, high-brightness seamless steel pipe produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm, while ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.

Product Features
Application
Mechanical structures, Hydraulic Equipment, Auto parts, Steel sleeves.
| Delivery Status | Code | |
| Cold working / hard | BK | No heat treatment is carried out after the final cold working, so that only a small deformation of the tube is possible |
| Cold working / soft | BKW | After the final heat treatment, a small amount of cold working is performed, and limited cold deformation (eg bending, flaring) is allowed for the end processing of the steel pipe. |
After Cold working Stress relief annealing | BKS | Annealing below Ac 1 after final cold working to relieve cold working stress |
| Annealing | GBK | Full annealing of the steel tube in a protective atmosphere after the final cold working |
| Normalizing | NBK | Normalizing of the steel pipe in a protective atmosphere after the final cold working |
