A gasket is a mechanical tool that helps seal connecting flanges and prevents leakage. It is used in various industries across applications and devices which include boilers, tanks, and piping among others. There is little doubt that these industrial gaskets have to withstand tremendous pressure, and are subjected to chemicals, fuels, and other hazardous substances. So, the material of these gaskets has to be robust, rust free and resistant to chemicals, abrasion, and more. Most metals react with certain chemicals or may wear out due to corrosion over time. Hence, non-metallic gaskets are commonly used for specific applications. This post discusses various types of materials that can be used to make non-metallic gaskets.
Choosing the Gasket Materials Based on the Application
There are various types of gaskets based upon their use or application, and their material, whether metallic, non-metallic, or semi-metallic, would be decided accordingly. Other factors include presence of chemicals or abrasive materials, extreme heat or cold, pressure bearing capacity, and others. Overall, the material of the gasket must match with all these requirements and withstand the required pressure and conditions. Here are some types of non-metallic materials used in gasket construction:
For highly corrosive applications and harsh environments, fiber glass, elastomers, graphite (flexible), and Teflon are the best options among non-metallic gasket materials. Here are some specific features of a few of these materials.
So, for a non-metallic gasket to be leak proof and function well, it is essential to choose the right material based on criteria such as temperature resistance, chemical resistance, flexibility, friction, strength, relaxation & compression properties, and so on. Depending upon the type of properties you require in your application, you can choose the right gasket material.
You can get in touch with industry experts to select the right material for your application. SSP Seals is one of the leading manufacturers of non-metallic industrial gaskets, including flange gaskets, and has a vast experience in designing and delivering the same across industries.
