12Cr1MoVG Seamless Tube Process Procedure:
Because of alloy pipes’ different manufacturing processes, they are divided into hot-rolled (extrusion) seamless and cold drawn (rolled) Seamless two. Cold drawn (rolled) pipe is divided into circular pipe and shaped pipe.
12Cr1MoVG Seamless Tube Process:
a. Rolled (extrusion seamless): round tube perforation →heating →three-roll rolling, rolling or extrusion →detached →sizing (or reducing) →cooling →billet tube →straightening →hydrostatic test (or testing) →mark →storage.
b. Cold drawn (rolled) seamless steel pipe: round perforated tube →heating→annealing →pickling →Heading oiled (copper) →multi-pass cold drawn (rolled) →heat treatment →straightening pipe billet straight →hydrostatic test (testing) →mark →storage.
Application: 12Cr1MoVG alloy structural steel tube is widely used in hydraulic prop, high-pressure gas cylinder, high pressure boiler, chemical fertilizer plants, petroleum cracking half-sleeve, automotive, and hydraulic fitting tube.
