What is the process flow of seamless steel pipe extrusion

Seamless steel pipe extrusion is a common steel pipe production process, usually used to produce high-precision, high-strength seamless steel pipes. The following is the process flow of seamless steel pipe extrusion:

1. Raw material preparation: Select high-quality steel billets as raw materials, and heat the steel billets according to requirements to reach a temperature suitable for extrusion.
2. Billet inspection: Conduct appearance inspection, dimensional inspection, and chemical composition analysis of the heated steel billet to ensure that the steel billet meets production requirements.
3. Perforation: The heated steel billet is fed into the punching machine for perforation to form a seamless tube shape.
4. Extrusion: The perforated steel billet is extruded through an extrusion machine so that it is gradually deformed into a seamless steel pipe under the action of the extrusion die.
5. Cooling: The extruded steel pipe is cooled through cooling equipment to ensure the stability and performance of the steel pipe structure.
6. Final inspection: Conduct appearance inspection, dimensional inspection, chemical composition analysis, and performance testing on the produced seamless steel pipes to ensure that product quality meets standard requirements.
7. Packaging: Qualified seamless steel pipes are packaged for transportation and storage.

The above is the basic process flow of seamless steel pipe extrusion. The specific production process may also involve more detailed process control and adjustments to ensure the production of high-quality seamless steel pipes.
