Flanges flat steel

Flanges flat GOST 12820-80 connect elements of pipeline fixtures operating under pressure from 0.1 MPa to 2.5 MPa and temperature from -80 ° C to +300 ° C. According to GOST 12820-80 flat flanges are produced with nine variants of sealing surfaces and geometrical sizes. For valves connection the first execution is often used, and at pressures over 16 atm. (1,6 MPa) and (or) usage of acidic, alkaline (aggressive) media the execution from 2 to 9 is chosen. Flanges flat steel according to GOST 12820-80 connect the pipeline with valves, pipeline parts with equipment, as well as to connect the various sections of the pipeline between themselves.
