As we knows that the steel pipe is likely to be rubbed if it is placed in the open air, and will be oxidized and rusted if the environment is wet. Therefore, most factories place the steel pipe in a sealed place as much as possible. However, precision seamless steel pipe has a unique advantage because its surface is not easily oxidized, which is mainly inseparable from the raw materials that make up precision seamless steel pipe. The precision stainless steel pipe relies on an thin, strong, dense and stable chromium-rich oxide film formed on its surface to obtain this ability to resist rust. And it has better toughness and wear resistance. Therefore, cleaning and maintenance should be do on the surface of the precision seamless steel pipe to better extend the service life of the precision seamless steel pipe. Precision seamless steel pipes are mostly used in the production of ring parts made of steel pipes such as oil drill pipes, automobile transmission shafts, bicycle racks and steel scaffolds used in construction, which can increase the service life of tools!

Features of cold drawn precision steel pipes

1. The outer diameter is smaller.

2. High precision can do small batch of products

3. The precision of cold drawn products is high and the surface quality is good.

4. The cross-sectional area of the steel pipe is more complicated.

5. The performance of steel pipe is more superior, and the metal is denser.

Because the inner and outer walls of the precision steel pipe have nonoxidation layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, and flattening without cracks, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders Cylinders can be seamless or welded. The chemical components of precision steel pipes are carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
