Ring type joint Gasket
About the product
Ring type joint Gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket, By applying pressure on the seal interface through bolt force, the softer metal of the gasket flows into the imperfections of the harder flange material, creating a very tight and efficient seal.
STANDARD RING JOINTS
|Style R (Oval Octagonal)
The contact face is in oval shape. It provides a high reliability seal. These gaskets are manufactured in accordance to API 6A of ASME B16.20 to suit AP1613 and ASME ANSI B16.5 Flanges. Fits the round and flat bottom ring groove flange
|Style R (Octagonal)
More accurate in dimension and surface finish than oval type because it consists of straight surfaces only. A higher torque load is required to flow the gasket material into imperfections of the flange facings. These gaskets comply with AP16A of ASME B-16.20 to suit API 6B and ASME ANSI B16.5 Flanges Fits only the modern flat bottom groove flange.
The BX type RTJ gaskets are manufactured in accordance with API 6A and are suitable for use in high pressure API 6BX flanges. The gaskets form a metal to metal seal on assembly and the efficiency improves as internal pressure relief hole to equalize pressure across sealing faces.
The RX type RTJ gasket is manufactured in accordance to API 6A and ASME B16.20 to suit API 6B and ASME ANSI B16.5 flanges. The RX is a pressure energized version of the R octagonal gasket and fits the R type flat bottomed groove. The RX has an increased height and utilizes the internal system pressure to energize and improve the seal as internal pressure increases. Some RX sizes have a pressure relief hole to equalize pressure
