Seamless Precision Pipe

Precision seamless pipe is a high-precision steel pipe material processed by cold drawing or hot rolling.

Precision seamless pipe is a high-precision steel pipe material that has been processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, they can withstand high pressure without leakage, have high precision, high smoothness, no deformation during cold bending, and no expansion. mouth, flattened without cracks and other advantages.

Therefore, products mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless pipes or welded pipes. The chemical composition of precision steel pipes is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical cross-section steel and is widely used in manufacturing structural parts and mechanical parts.

Seamless precision tubes are widely used in automobile manufacturing, aerospace, machinery manufacturing, electronic equipment, instrumentation and other fields. In these areas, the requirements for pipe size and surface quality are very high.

Precision seamless pipes are usually produced by cold rolling.

The specific process is as follows:

Round steel → perforation → pickling → cold rolling → saw → bundling

Seamless pipe → pickling → cold rolling → saw → bundling

Features

1. High precision, which saves the loss during mechanical processing of user materials.

2. Multiple specifications and wide range of applications.

3. The cold-rolled finished product has high precision, good surface quality and good straightness.

4. The inner diameter of the steel pipe can be made into a hexagonal shape.
