Aigi – Ring Joint
A solid metal gasket that is softer than the mating flange material that is virtually ‘crushed’ into the flange face, creating a seal by filling imperfections and leak paths with gasket material. Under high sealing stress the gasket deforms but not the flange. They are used predominantly in the petrochemical industry (offshore oil platforms, refineries) due to the high service pressures required in their processes. Ring joint gaskets are machined to exact specifications and tight tolerances and come in a number of styles.
Common materials used for the manufacture of ring joint gaskets:
- Soft Iron
- Low Carbon Steel
- Stainless Steel
- Monel®
- Inconel®
- Incoloy®
- Hastelloy®
