What is a ring joint gasket

Ring Joint Gasket is widely used in oil, petroleum and chemical process fields. Precision machined, metallic sealing rings suitable for high pressure and high temperature applications.

Ring joint gasket is manufactured in accordance with API 6A and ASME B16.20 specifications and come in various profiles.There are four basic profiles: Oval type R, Octagonal type R, RX and BX.

Description

Oval Ring Joint Gasket Standard style R ring type joints are manufactured in accordance with both API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal configurations, These gaskets are used in pressures up to 10000 PSI. Oval Ring Joint Gaskets are for oilfield and process industry duties.

Octagonal Ring Joint Gasket Standard style R ring type joints are manufactured in accordance with both API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal configurations, These gaskets are used in pressures up to 10000 PSI. Octagonal Ring Joint Gaskets are for oilfield and process industry duties.

RX Ring Joint Gasket RX is a pressure- energized adaptation of the standard Style R gasket. The modified design uses a pressure – energized effect that improves the efficiency of the seal as the internal pressure of the system increases.

BX Ring Joint Gasket BX pressure energized gaskets are manufactured in accordance with API 6A and are designed for use on pressurized systems up to 20,000 PSI. on both the inner and outer diameters. All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.

BX Ring Joint Gasket

The type BX energized ring type joints, manufactured in accordance with API 6A, are designed for use on pressurized systems up to 20,000 psi.

When correctly fitted, the type BX gasket allows virtual face to face contact of the flange faces which means that the gasket in fully trapped on both the inner and outer diameters.

All BX gasket incorporate a pressure balance hole to ensure equalization of pressure which may be trapped in the grooves.

Standard

Standard style BX ring type joints are manufactured in accordance with both API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal configurations, both types are interchangeable on the modern octagonal type grooved flanges

As with all metal ring type joints including style BX, it is recommended to replace the ring when flange connection is broken.

RX Ring Joint Gasket

The style RX is an adaptation of the standard style R which energizes on assembly. The RX is designed to fit the same groove design as a standard style R, making the joints interchangeable.

Consideration should be given to the difference in finished make-up distance.

The modified design uses an energizing on assembly effect with improves the efficiency of the seal.

Standard

Standard style R ring type joints are manufactured in accordance with both API 6A and ASME B16.20 size and ratings. Available in both oval and octagonal configurations, both types are interchangeable on the modern octagonal type grooved flanges.

As with all metal ring type joints including style RX, it is recommended to replace the ring when flange connection is broken.
