Cameroon ring gaskets also known as mental joint gasket ,ring gasket including three different kind of products , respectively are R(oval ring joint gasket ,Octagonal ring joint gasket ),RX mental gasket and BX mental gasket .It is usually used for joint Of API RJ flange ,suitable for high pressure and temperature in petrochemical industry
The product is the solid mental gasket made of mental materials by forging heat treatment and machining into cross section shape of oval or octagonal . It has good sealing as the contact between gasket and the ring joint faces, especially the outside face, and is pressed tightly to keep good sealing performance.
section views as below :
1.Cameroon mental gasket is used for stressful RJ flange connection ,the high the pressure is the better the sealing performance is
2.Cameroon mental gasket suitable for type of 6BX flange (the middle circle of the flange is higher than the circle face of bolt hole ) it has the line seal with good seal performance, but it should have high accuracy;
3. Cameroon mental gasket can not interchange with other sealing products
4.Usually ,the Cameroon mental gasket can be only used one time
5.The hardness of the Cameroon mental gasket must be 15-20HB lower than meting flange face
6.The seal face of Cameroon mental gasket including the bevel faces ,shouldn't have the scratches ,knock marks ,cracks and defects ,the surface roughness shouldn't large than Ra0.8

The gaskets are primarily used in the oil, gas, petrochemical and offshore industries. They are also commonly used on valves, ,RJT flange ,Xmas tree ,blowout preventer ,pipe-work assemblies and vessel joints and are used to seal flanged connections subject to high pressures and temperatures.
It can provide any standard and non-standard sizes, including the standards of API 6A, API 17D, ASME B16.20, DIN 2693-67, JPI-7S-23-72 and other standards.
