BX RX R Series Ring Joint Gasket

BX RX R Series Ring Joint Gasket

BX RX R Series Ring Joint Gasket

Description


Product Description

Ring Joint Gasket is machined from solid metal in a variety of shapes and designed for high pressure, high temperature or highly corrosive applications by selecting the most suitable material and shape. It is designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses.

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

 

Application

They seal by creating very high unit load, metal-to-metal line contact with special mating flanges. Metals are typically chosen such that the ring joint gasket is softer than the flange material in order to prevent damage to the flanges and thereby causing plastic flow of the gasket into the flange faces. The design of the gasket or cross section is chosen based on the existing flange configuration and designed maximum system pressure. Gasket and flange surface finishes and dimensional accuracy along with gasket hardness must be carefully controlled in order to obtain and maintain an effective seal.
