Material of high pressure pipeline

　　We should choose according to the characteristics of the material before selection. The material of the fitting is the basic property of the fitting and the foundation of the fitting. As a qualified salesman or technician, the material parameters of pipe fittings should not be confused.

　　The known forging materials of seamless high-pressure pipeline are F92, F91, F22, P91 and p92.wb36.

　　Each fitting has a different material.

　　In China's chemical industry standard, the pipeline with pressure ≥ 16MPa is called high pressure pipeline. High pressure pipeline are used in specific environment such as high pressure steam equipment, chemical high temperature and high pressure pipelines, pressure vessels of power plants and nuclear power plants, high pressure boiler accessories, etc.

　　The materials of high-pressure pipelines are 20g, 20mng and 25mng. 15mog, 20mog, 12crmog, 15CrMoG, 12CR2MOG 12crmovg, 12Cr3MoVSiTiB 1Cr18Ni9, 0Cr18Ni9, 1cr18ni11nb, etc.
