SRX Ring Joint Gasket

详情

SRX series are American Petrolium standardized underwater rings. the RX and SRX will fit into their appropriate flange designated numbers. The " S " prefix identifies a gasket as having intersecting vent holes, allowing a pressure less metal-to-metal initial contact between the gasket and flange groove, while made up underwater.
Features
1.SRX Ring Joint Gaskets is the same design as the RX Ring Joint, however the suffix "S" indicates that additional pressure equalisation holes have been drilled to prevent pressure lock in accordance with API *7D for use on sub sea wellhead and christmas tree equipment.
2.SRX Ring Gaskets solve a problem principally occurring when joining 6BX and/or *7D  RTJ flanges under water.
3.SRX gaskets have a bleed hole on their I.D. joining to their equalizing hole, to assure that any liquid trapped behind the ring gasket on either side will vent (flow) to the I.D. bore of the assembly as the connection comes together. This allows the connection to close as designed and the ring gasket to coin and form a permanent seal.
4.Gaskets that have been torqued initiating a metal-to-metal seal should be discarded and not reused.
