The production process of ASTM A213 seamless steel pipes is as follows:
1.Material selection: Choose appropriate alloy steel as raw material.
2.Heat treatment: Heat the billet to the appropriate temperature and then cool it for a certain duration to change the material's microstructure and properties.
3.Hot rolling or cold rolling: Press the heat-treated billet into a tube blank.
4.Hot forming: Heat the tube blank to the appropriate temperature and use a mold to shape it into a tube.
5.Heat treatment: Further heat treat the tubular billet to improve its mechanical properties.
6.Finishing: Process the tube blank into the final seamless steel pipe through processes like rolling and cutting.
7.Inspection and testing: Conduct various inspections and tests on the seamless steel pipe to ensure its quality meets the standard requirements.
8.Surface treatment: Perform surface treatments like derusting, acid pickling, and anti-corrosion coating on the seamless steel pipe as required.
9.ASTM A213 T2, T11, T12, T22, and T91 seamless steel pipes are produced through the above process.
