The biggest advantage of P11 Alloy Steel Pipe is that it can be recycled 100%, which is in line with the national strategy of environmental protection, energy saving and resource saving. The expansion of the application field of P11 alloy steel tube provides a broader space for the development of the industry. Hydrogen will not cause obvious corrosion to P11 steel pipes under normal temperature and pressure, but when the temperature exceeds 300 ° C and the pressure is higher than 30 MPa, the corrosion defect of hydrogen embrittlement will occur, especially under high temperature conditions.
P11 alloy Steel Pipe: Because of its different manufacturing processes, it is divided into two types: hot-rolled (extruded) Seamless Steel Pipe and cold-drawn (rolled) seamless steel pipe. Cold drawn (rolled) tubes are divided into two types: round tubes and special-shaped tubes.
craft. Hot rolling (extruded seamless steel pipe): round tube billet → heating → perforation → three-roller skew rolling, continuous rolling or extrusion → tube removal → sizing (or diameter reduction) → cooling → billet tube → straightening → water pressure Test (or flaw detection) → mark → storage. Cold drawn (rolled) seamless steel pipe: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet → heat treatment → straightening → Hydraulic test (flaw detection)→marking→warehousing.

Alloy Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel tube is lighter in weight when the bending and torsional strength is the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission Axles, bicycle racks and steel scaffolding used in building construction, etc.
