Ring Type Joints are primarily used by the oil, gas, petrochemical and offshore industries, they are also commomly used on valve, pipe work assmebilies and with some integrity vessel joints. Ring Type Joints are use to seal flanged connections subject to high pressures and teperatures. These precision made solid metal gaskets form a metal to metal seal with the flanges. The gasket cross-sections are designed to concentrate the bolt load over a small area to produce a high seating stress. The gasket metal should always be softer than the mating flanges. The high seating stress causes ‘plastic-flow’ of the gasket into the flange faces to create the seal. The ‘RX’ and ‘BX’ gaskets are designed to be pressure activated by the sealed media which improves the efficiency of the seal as the internal pressure of the system increases.
‘R’ series Ring Type Joints can contain pressure up to 10,000 PSI
‘RX’ and ‘BX’ series Ring Type Joints can contain pressure up to 20,000 PSI
The gasket and flanges must be manufactured to precision dimensions, surface and hardness.
