The RTJ flange has a circular groove on its face with a metal ring gasket that fits into the groove. When the flange is bolted, the metal ring gasket is compressed between two flanges, creating a tight and leak-proof seal. This design allows the RTJ flange to withstand extreme pressure and temperature conditions.
20MnMo for forging steel parts are used to manufacture pressure vessel components, important forgings, etc. of -40 ° C ~ 470 ° C. The carbon content is 0.2%, and the content of MN and MO is less than 1.5%. The chemical composition of this forging parts mainly include C, Si, MO, MO, CR, Ni and other alloy elements. The chemical composition of the nuclear pressure vessel with SA508-3CL.2 steel is very similar to it.
