The biggest advantage of 12Cr1MoVG steel pipe is that it can be recycled 100%, in line with the national strategy of environmental protection, energy saving, and resource saving. The national policy encourages the expansion of the application field of high-pressure 12Cr1MoVG steel pipe.
The technological process of 12Cr1MoVG steel pipe:
Hot-rolled 12Cr1MoVG steel pipe: round tube blank → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → pipe removal → sizing (or reducing) → cooling → billet tube → straightening → hydraulic test (or flaw detection) →Mark→Warehousing.
Cold drawn 12Cr1MoVG steel pipe: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet tube → heat treatment → straightening → hydraulic test ( Flaw detection) → mark → warehousing.
