Welcome Your Order From Top Ring Joint Gasket Manufacturer
Ring joint gasket and metal ring gasket from Ginseal Ring Joint Gasket Manufacturer offers high temperature and pressure sealing with good recovery performance.
There are 4 types of ring type joint gasket:
RTJ Gasket Size Chart
Type R ( oval/ octagonal ) Ring Type Gasket
- Item No.: JSG – RJR1 / JSG- RJR2
R Style seal ring gasket or named oval gasket as the basic type of RTJ gasket is available in both oval and octagonal configurations, the octagonal ring joint gasket is recommended in higher sealing efficiency, both types are interchangeable on modern octagonal type grooved flanges. However, only the oval cross-section can be used in the old type round bottom groove as the oval ring gasket are the original type of RTJs.
R type ring gaskets are manufactured in accordance with ASME B16.20 followed with ASME B16.5 flanges, class 150 to 2500. They are designed for sealing pressure up to 6,250 psi according to ASME B16.5 pressure ratings.
R series flange ring gasket is available in ring numbers R11 up to R105, Ginseal also can provide customized R type RTJs with drawings.
Type RX RTJ Ring Gasket
- Item No.: JSG – RJRX
Ginseal RX ring type joints are similar in the shape of the octagonal ring gasket, while the RX type rings’ cross-section is designed to take advantage of the contained fluid pressure in effecting a seal. RX ring joint gaskets are also manufactured according to API 6A, ASME B16.20. The ring-type joints are used at pressures up to 15000 psi, and the RX type is wider than R type joints in this way the flange face to face separation will be higher compared with the R type gaskets.
RX ring joint flange gasket 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.
Type BX RTJ Joint Gasket
- Item No.: JSG – RJ BX
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 RJ gaskets incorporate a pressure balance hole to ensure equalization of pressure that may be trapped in the grooves.
BX type ring joint flange gaskets are engineered for the highest pressure ratings up to 20,000 psi compared with R type & RX type ring joints. They cannot be interchangeable with any other types like R type or RX type. It is a typical solution required by a special arrangement.
Blowout resistance, opening in the axial direction gives the BX type ring type joint gaskets the function of balancing the pressure loads in the situation when the inner sealing barrier is not tight.
BX ring gaskets are manufactured only in the dimension standards to NPS 30.
Type SBX / SRX
- Item No.: JSG – RJ SBX/ RT SRX
Type SRX and SBX metal ring joint gaskets are manufactured as per API 17D for Subsea environment and Tree Equipment are vented to prevent pressure lock when connections are made up underwater. They have the same dimensions as Type RX & BX RTJ ring joint gasket with the same number designation, and also they are suitable for the same corresponding connectors. The “S” prefix shows these gaskets have vent holes, allowing a pressure less when underwater. With the vent holes, any water trapped between a ring groove bottom and the sealing area of the gasket can escape to the equipment I.D. bore.
Ginseal RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. It is essential to choose a softer metal of the gaskets while the flange’s material should be harder to make sure the ring type joints can give a very tight and efficient seal after applying pressure on the sealing interface through bolt force. Usually, the ring gaskets are used in oil, petroleum and chemical process fields. As precision machined, metallic sealing rings, ring joints are suitable for high pressure and high-temperature applications.
