13CrMo44 steel manufacturing process:
1. Hot-rolled (extrusion seamless): round tube perforation → heating → three-roll rolling, rolling or extrusion → detached → sizing (or reducing) → cooling → straightening → hydrostatic test (or testing) → mark → storage
2. Cold drawn (rolled) seamless steel pipe: round tube perforation → heating → annealing → pickling → Heading oiled (copper) → multi-pass cold drawn (rolled) → billet tube straightening → water → heat treatment → pressure test (testing) → mark → storage.
13CrMo44 steel plate application:
13CrMo44 steel plate is widely used in petroleum, chemical engineering, power plants, boilers and other industries for the production of the reactor, heat exchangers, separators, tank, gas tank, nuclear reactor pressure vessel, boiler, liquefied petroleum gas cylinders, Hydropower high-pressure pipes, turbine spiral case equipment and components.
