Understanding Flange Metallic Gaskets
Flange metallic gaskets are essential components in various industrial applications, particularly in the oil and gas industry. They are used to create a static seal between two flange faces, under different operating conditions, with varied pressure and temperature ratings.Get more news about

Types of Flange Gaskets
There are several types of flange gaskets, each with its unique properties and applications. The most common types include non-asbestos gaskets, spiral wound gaskets, and ring joint gaskets.
Non-Asbestos Gaskets
Non-asbestos gaskets are the simplest type of gasket for flanges. They are produced by cutting graphite, organic, or inorganic non-asbestos sheets into shape. These gaskets suit low pressure, low temperature, and non-critical piping and plumbing applications. Non-asbestos gaskets have fully replaced asbestos gaskets due to the health risks associated with the production, use, and disposal of asbestos materials.
Spiral Wound Gaskets
Spiral wound gaskets feature a metal sealing element filled with graphite, PTFE, ceramic fibers, and non-asbestos fibers. These gaskets are classified as “semi-metallic” gaskets. They are ideal for standard flanges, heat exchangers, boiler handholes, manholes, and other high-temperature, high-pressure applications3.
Ring Joint Gaskets
Ring joint gaskets are used for RTJ flange faces. They are suitable for higher temperature and pressure oil and gas applications.
Conclusion
In conclusion, flange metallic gaskets play a crucial role in ensuring the integrity and efficiency of industrial systems. Selecting the right gasket type is vital for the safe and efficient operation of these systems.
