Introduction for different types of gaskets used in piping

A gasket can be broadly classified into three categories.

• Non-Metallic
• Metallic
• Composite
• You can see the table in which I have listed the most commonly used gasket against each category.

Compressed Non-Asbestos Fibre Gasket that is known as a CNAF gasket, PTFE gasket, and rubber gasket are non-metallic type gaskets. These gaskets are used in a non-critical application where pressure and temperature are not involved. CNAF and rubber gasket is used on an application such as utility water, temporary line whereas PTFE gasket is used for corrosive services where metal gasket cannot be used.

Metallic gaskets

Metal gaskets are manufactured from a material such as Soft iron, Low Carbon steel, Stainless Steel, Monel, and Inconel. These gaskets are Also known as ring gasket or RTJ gaskets. A metallic gasket is used in high-pressure class flanges,normally above 900 Class,they can also be used in high pressure-temperature services.

Composite gaskets are a combination of metal and non-metal material. Different types of combination of materials are possible based on service requirement. Spiral wound, Metal Jacketed, and camprofile gasket are well known in the composite gasket category. They can be Used in a wide range of pressure and temperature. Composite gaskets are Cost effective with compare to metal gaskets, but Careful handling is required.
