Precision steel pipe is a seamless steel pipe with high outer diameter accuracy, inner diameter smoothness and wall thickness consistency. It is mainly used in the following fields:

1. Machinery manufacturing industry: precision Steel pipes are mostly used to manufacture various mechanical parts with high precision, high finish, and high wear resistance, such as automobile engines, air compressors, computer printers, etc.

2. Hydraulic and pneumatic transmission systems: High-precision oil pipes and air pipes are required in hydraulic and pneumatic transmission systems to meet the system's strict requirements for transferring fluid or gas.

3. Petrochemical industry: Because precision steel pipes have good high temperature resistance and corrosion resistance, they are widely used in oil well pumping, chemical equipment, offshore oil platforms and other fields in the petrochemical industry.

4. Medical device and instrument testing: Medical device and instrument testing requires high precision. The high precision, high smoothness, high corrosion resistance and other properties of precision steel pipes make it an ideal choice for medical devices and instruments. Indispensable parts for testing.

In short, precision steel pipes have special properties such as high precision, high smoothness, and high corrosion resistance, and therefore are widely used in many industries.
