Specification
Precision steel pipe is a kind of common seamless steel pipe (or reduced diameter welded steel pipe) through fine drawing or cold rolling processing after a high precision steel pipe material. Because the inner and outer walls of the precision bright tube have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless tubes or welded tubes.
The chemical composition of precision bright tube is carbon C, silicon Si, Manganese Mn, sulfur S, phosphorus P, chromium Cr. High quality carbon steel, finished rolling, no oxidation bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is SCrubbed by special equipment and washed by high pressure, the antirust oil on the steel pipe is used for antirust treatment, and the two ends of the cover is used for dustproof treatment. The inner and outer wall of the steel tube is of high precision, high finish, no oxide layer of the steel tube after heat treatment, high cleanliness of the inner wall, the steel tube is under high pressure, no deformation in cold bending, no cracks in flaring and flattening.
Application:
Automobile, mechanical parts, such as steel pipe precision, finish has high requirements of machinery. Precision steel pipe users are not only the users with high requirements for precision and finish, because the precision bright pipe is high, the tolerance can be maintained at 2-8 wire, so many mechanical processing users in order to save the loss of labor, material and time, the seamless steel pipe or round steel is slowly transformed into precision bright pipe.
Characteristics:
1. The outer diameter is smaller.
2. High precision can be used for small batch production.
3. Cold-drawn products have high precision and good surface quality.
4. The transverse area of steel tube is more complex.
5. Steel pipe has better performance and denser metal.
6. Cold-drawn products have high precision and good surface quality.
7. The transverse area of steel tube is more complex.
8. Steel pipe has better performance and denser metal.

Process
As we know, most of precision steel pipe has cold drawn and hot rolled process. On the contrast, cold rolling will be more complicated. Not only the pipe need to be continuous rolled by three roller, but also the test have to be done after extrusion, so to guarantee the quality of the precision pipe materials.
Manufacturing methods of seamless precision pipe includes hot rolling and cold drawn. More over it could be manufactured in welding processes.
