RS-5002 cc is by smithing, heat treatment and mechanical processing. it is suitable for oil or gas pipe flange,pressure vessel, high speed joint face, valve with high temperature and high pressure. it has good sealing performance even when the pressure and temperature is not stable.the typical style r are divided into ellipse style and octagonal style according to its cross section. it can be ordered to two different profiles, oval or octagonal in cross-sections. Both types have identical pitch diameter as the flange groove they correspond to. These gaskets are used in pressures up to 10,000 PSI. The octagonal type has a higher sealing coeffient than the oval, therefore being the better gasket of the two. The oval type is the only gasket that will fit a bottom radiused groove. Flanges with flat bottom v-grooves will accept either style. Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
