AT811-AT816 Ring Joint Metal Gaskets

Ring Joint Metal Gasket is manufactured by machining from an after forging and heat treatment metal blank. The sealing surface is a line or a regular shape,giving excellent rigidity and strength to the product which is well suitable for high-pressure steam,gas and solvent condition in high-pressure vessel,valve and reactor.The most common industry product is R type Ring Joint Metallic Gasket which is classified into oval style and octagonal style according to their crosssections. There are various standards but almost all the standards have similar dimensions so that Ring Joint MetalGaskets could be universal.RX and BX types are the improved generations of Ring Joint Metal Gaskets. The maximumoperating pressures are 2500PSI(17MPa)and 15000PSI(100MPa)for RX and BX,respectively.The Lens type could beused over 300MPa.
