Production Process of 304 Precision Seamless Tube

 

1. Material selection: The raw materials of 304 stainless steel pipes are made of high-quality stainless steel plates and strips to ensure uniform composition and stable performance of the steel pipes.

2. Hot-rolled or cold-drawn: 304 precision seamless tubes are usually made by cold-drawn or hot-rolled processes. Cold-drawn steel pipes are formed by cold working to ensure dimensional accuracy and surface quality.

3. Annealing treatment: The steel pipe after cold drawing needs to be annealed to eliminate cold working stress and improve the mechanical properties and corrosion resistance of the pipe.

4. Precision machining: The outer diameter, wall thickness and length of precision seamless tubes have high accuracy requirements, so strict dimensional control and surface machining are required to achieve high precision requirements.

5. Testing and Inspection: Strict quality control is carried out at every stage of the production process, including appearance inspection, dimensional measurement, and non-destructive testing (such as ultrasonic testing, X-ray testing, etc.) to ensure that the quality and performance of the steel pipes meet the standards.
