Ring Type Joint Gaskets

Metallic gaskets, which are manufactured from a variety of metals and alloys, usually oval or octagonal in cross-section, depending on the flange design.

Ring joints are designed to serve at high pressure (up to 1500 bar) and high temperature (up to 1000 C) applications. Very safe and reliable sealing system; will be always applied, when aggressive media or explosive gases are involved; Risk in the choice of ring joint material: the ring joint material must be softer than the flange material but the hardness of the flange material is normally not indicated

Metal to metal sealing; requires therefore good (ra < 1,6) flange surface
