Ring joint gaskets (RTJ) ensure a long lasting and strong seal for flanges, valves, piping spools and vessels at high pressure and temperatures (which are typical conditions for many petrochemical processes).

RTJ GASKETS TYPES

R Type Ring Joint Gasket (Oval and Octagonal)

"Style R" is the most common RTJ gasket type. R type ring joint gaskets are available in oval or octagonal cross-section and manufactured according to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges.

This type of RTJ gasket is machined to tight manufacturing tolerances to ensure correct installation with standard ASME B16.5 and API 6B ring joint faced flanges. "R style" oval and octagonal RTJ gaskets can seal pressures up to 6.250 psi by ASME B16.20 and up to 5.000 psi according to the API 6A pressure ratings.

Type R RTJ gaskets are frequently used for valves covers.

Style RX RTJ Gasket

The RX type RTJ gasket is manufactured according to API 6A and ASME B16.20 to suit API 6B and ASME/ANSI B16.5 flanges.

The RX is a pressure energized version of the R octagonal gasket and fits the R type flat-bottomed groove.

The RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increases.

Some RX sizes have a pressure relief hole to equalize pressure on both sides of the sealing faces.

Style BX RTJ Gasket

The BX type RTJ gaskets are manufactured according to API 6A and are suitable for use in high-pressure API 6BX flanges.

The gaskets form a metal to metal seal on assembly and the efficiency improves as internal pressure increases.

All BX sizes have a pressure relief hole to equalize pressure across sealing faces.
