SEALS & GASKETS
Industrial seals are used to prevent leakage, hold pressure, and deflect contamination at interfaces between components.
Mechanical seals are devices that are used to provide a seal at the point of entry or exit of a rotating shaft. Typically it is used to prevent the leakage of one high pressure fluid into a lower pressure fluid.
The most common materials used for this type of gaskets are Graphite, Rubber, Teflon, PTFE, and Compressed Non-Asbestos Fiber (CNAF). These gaskets are also known as a Soft gasket. It can be full face or inside bolt circle type
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.
Composite gaskets are a combination of metal and non-metal material. Different types of combinations of materials are possible based on the service requirement.
SPIRAL WOUND GASKET
The most widely used composite type gasket is a Spiral Wound Gasket. It is suitable for a wide range of pressure and temperature class. Normally Graphite or PTFE used as filler material & stainless steel or other exotic material is used as the winding material.
