GB 5310 12CrMoVG High Pressure Alloy Pipes Process

GB 5310 12CrMoVG pipe is seamless steel tube and pipe for high pressure purpose. At present, China's 12Cr1MoVG alloy tube consumption accounted for the proportion of total steel content is only half of the developed countries, 12Cr1MoVG alloy pipe to expand the use of the field for the development of the industry to provide a broader space. According to the China Special Steel Association 12Cr1MoVG alloy pipe branch of the study, the future of China's high-pressure 12Cr1MoVG alloy pipe material demand growth of up to 10-12%.

GB 5310 12Cr1MoVG alloy tube is the biggest advantage of 100% recovery, in line with environmental protection, energy saving, resource conservation strategy, national policy to encourage the expansion of high pressure 12Cr1MoVG alloy pipe applications.

Because of its different manufacturing process, 12Cr1MoVG seamless steel pipe is divided into hot-rolled (extruded) seamless steel pipe and cold drawn (rolling) seamless steel pipe two. Cold drawn (rolling) tube is divided into two kinds of circular tube and shaped tube.

Overview of the process

Hot-rolled (extruded seamless steel pipe): round tube → heating → perforation → three roll skew rolling, continuous rolling or extrusion → off pipe → sizing (or reducing diameter) → cooling → billet → straightening → water pressure Test (or flaw detection) → mark → storage.

(Cold-rolled) → billet → heat treatment → straightening→ Water pressure test (inspection) → mark → storage.
