The RTJ Ring Joint Gasket was initially developed for high pressure or temperature applications found in the petroleum industry and is primarily used in the oil field on drilling and completion equipment. However, today this product range can also be found on valves and pipework assemblies, along with some high integrity pressure vessel joints.
RTJ ring joint gasket product details
Standard Type R RTJ ring joint gaskets are manufactured in accordance with both standard API 6A and ASME B16.20 size/ratings. Available in both oval and octagonal configurations, both types are interchangeable on the modern octagonal type grooved flanges. As with all solid metal Ring Type Joints including Style R, it is recommended to replace the ring when flange connection is broken.Type RX ring joint gasket is an adaptation of the standard Style R which energizes on assembly. The RX RTJ 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 which improves the efficiency of the seal. Designs are also available for SRX Subsea applications.
Type BX RTJ ring joint gaskets are pressure energized gaskets manufactured in accordance with API 6A and designed for application pressure up to 20,000 psi. All BX gaskets incorporate a pressure balance hole to ensure equalization of pressure which may be trapped in the grooves.
Type SBX ring joint gaskets are based on the BX gasket design. They are designed with a special vent hole drilled into it for underwater application. Style SBX RTJ gaskets are made in accordance with API 17D.
