Supply octagonal ring gasket

 Octagonal metal gasket by the forging and heat treatment and machining made a applied to oil and gas pipe flanges, pressure vessels, high-speed joints, such as high temperature and high pressure valve cover gasket metal, in particular pressure, temperature fluctuation of the occasion, still maintain a good seal. Commonly used by R-type gasket into oval or octagonal cross-section type, the standard R type ring gasket according to API 6A and ASME B16.20 standard sized, the maximum working pressure is 10000PSI. In the trapezoidal groove flange octagonal pad with oval mat can be interchanged. RX-type octagonal pad for pressure enhanced standard R type ring gasket, suitable for R type as the flange groove sealing surface. BX type octagonal pad for pressure and designed to enhance the application of up 15000PSI pressure system. There are a variety of materials and forms for different design and operating requirements, reference material characteristics table. Note: use octagonal pad material hardness should be below the flange surface 15 ~ 20HB, and re-use is not recommended.
