Semi-Metallic gaskets are a combination of metal and non-metal materials. Different types of combinations of materials are possible based on the service requirement.
Spiral wound, Camprofile, Metal Jacketed, and Metal – Rubber gasket are well known in the composite gasket category. They are used in a wide range of pressure and temperature services.
Composite gaskets are cost-effective compared to metal gaskets, but Careful handling is required. Composite gaskets are used on raised faces, male-female, and tongue-and-groove flanges.
