Stainless steel seamless pipe manufacturing process:
1. Raw material preparation: Select qualified raw materials that meet the specifications for stainless steel pipes, usually round billets.
2. Hot rolling or cold drawing: After heating the round steel billet to an appropriate temperature, the billet is rolled or drawn into the shape of a seamless pipe through the hot rolling or cold drawing process.
3. Heat treatment: Anneal or heat treat the stainless steel seamless pipe to relieve stress and improve the grain structure and mechanical properties of the pipe.
4. Size adjustment: adjust the size of the stainless seamless pipe by cold drawing, cold rolling, or cutting to meet the specification requirements.
5. Surface treatment: Surface treatment such as pickling, shot blasting or polishing is carried out to improve the surface finish and quality of the seamless stainless tube.
6. Inspection and testing: conduct various tests on seamless pipes, such as chemical composition analysis, mechanical performance test, etc., to ensure product quality.
7. Packing: Pack the seamless ss pipe for transportation and storage.
