BX and SBX Type Ring Joint Gaskets for High-Integrity Sealing
BX and SBX Type Ring Joint Gaskets are made from a variety of metals to accommodate a range of industrial processes. BX and SBX Gaskets form a seal between their mating flanges by deforming under very high pressures. BX Ring Joint Gaskets incorporate a pressure balance hole to prevent pressure forming in the grooves.
BX and SBX Type Ring Joint Gaskets provide a high-integrity seal and are designed specially for use in very high-pressure applications. (Pressure ratings range from 5,000 PSI to 20,000 PSI.) BX and SBX Gaskets are similar in style to standard Octagonal Gaskets, but are manufactured specifically to complement 6BX flanges and 16BX hubs.
SBX Ring Joint Gaskets Process
The SBX Type Ring Joint Gasket includes intersecting vent holes that facilitate seal formation when the gasket and flange are submerged in water. This makes SBX Gaskets ideal for underwater applications. SBX Type Gaskets use non-corrosive material (per requirement of API 17D). The pressure rating of an SBX Gasket is equal to that of the corresponding BX Type Ring Joint Gasket. There is no dimensional difference between corresponding BX and SBX Type Gaskets.
The Pitch diameter of a BX or SBX Gasket is slightly greater than that of the mating flange. Consequently, the outside angles seal first, followed by the inside angles, as the flange is bolted down.
BX and SBX Type Ring Joint Gaskets are available from BX150 to BX303. Dimensions and tolerances are as per API 6A (pressure passage hole details stated in API 17D).
BX and SBX Type Gaskets that have been torqued to form a metal-to-metal seal should be discarded following removal.
