Ring Joint Gasket
The Ring Joint Gasket mainly used in high pressure, temperature applications in the petroleum industry. Mostly used for Valves, Pipes and Flanges.
Standard R type are accordance with API 6A and ASME B 16.2 size. For both Oval and Octagonal configurations. They can interchange on the modern octagonal type grooves flange.
RX Type ring joint gaskets are manufactured to fit the API 6B flange"s groove, interchangeable with R(oval) and R(octagonal) series, bear pressure can reach to 15000 PSI, so these gaskets performance excellent in 6B flange, suitable to the higher pressures with higher vibrations and heavier weights of these units.
Spec.: RX20~RX215
BX type ring joint gaskets are designed for BX flange grooves only, it is suitable for higher-pressure ratings starting at 2, 000 lbs and ending with 20, 000 lbs, incorporate a pressure balance hole to ensure equalization of pressure which may get trapped in the grooves.
Type: BX, RX, R(Oval & Octagonal)
Materials: Carbon Steel, Soft Iron, SS304, F5, 321, 304L, 316L, 316, 347. Or other materials according to your request.
Material 5Cr1/Mo (F5), recognized as 1.7362 in DIN standard.
Spec.: R11~R105
BX150~BX303
RX20~RX215
More than 20 years' experience in this line, our high quality products have meet a favorable reception.
