Metal ring gasket is made of forging and heat treatment and machining, which is a kind of metal sealing gasket, pressure vessel, high-speed combination surface, high temperature and high pressure gasket, especially the pressure and temperature fluctuations, can still maintain a good seal. The commonly used R-shaped spacers are divided into elliptical or octagonal according to the section, and the standard R-shaped ring spacer is manufactured in API 6D and ASME B16.20, with the maximum use pressure of 10000PSI. The octagonal gasket is interchangeable with the oval gasket in the trapezoidal groove flange. The RX octagonal gasket is suitable for pressure enhanced standard R-shaped ring spacers, suitable for R-shaped flange groove sealing surfaces. The BX octagonal gasket is suitable for pressure enhancement and is designed to apply up to 15000PSI pressure systems. There are a variety of materials and forms suitable for different design and operation requirements, refer to the material characteristic table.

Attention please:

The hardness of octagonal cushion should be lower than 15-20HB of the flange surface, and it is recommended not to reuse it. Applied Code
