Flange Gaskets: Definition, Types, Installation, and Maintenance
Flange gaskets play a crucial role in ensuring seamless connections within piping systems across various industries. These connections help keep fluids and gases contained within the pipes, preventing leakage. In this article, we’ll explore the definition, types, installation, and maintenance of flange gaskets.Get more news about Flange Metallic Gasket,you can vist our website!

What Is a Flange Gasket?
A flange gasket is a sealing component used to secure tight connections in pipes and piping systems. The end surfaces of these pipes protrude or flare out, commonly referred to as “flanged.” Flange gaskets resemble circular rings designed to fit the mating, flanged surfaces of pipes. They are typically made from rubber, silicone, or metals. The primary function of flange gaskets is to create a tight seal between flanged pipes, preventing the leakage of fluid and gases.

Different Types of Flange Gaskets
Rubber Gaskets: These gaskets, made from materials like NBR, EPDM, and CR, find applications in various machine and equipment constructions. In chemical and food industries, Viton® and silicone rubber gaskets are often used.
Fiber Gaskets: ERIKS offers a wide range of fiber gaskets in standard dimensions (DIN and ASME), readily available from stock. Specialty and small quantities can be processed in automated cutting facilities.
Graphite Gaskets: Specifically designed for high-pressure steam, chemical, and petrochemical industries, high-quality graphite gaskets are available.
PTFE (Polytetrafluoroethylene) Gaskets: PTFE gaskets offer outstanding chemical stability, making them ideal for use in the chemical industry. Many PTFE products are FDA-approved, making them suitable for food and pharmaceutical applications.
Purpose of Flange Gaskets
The primary purpose of flange gaskets is to ensure a stable, tight connection or seal between the mating surfaces of flanges in a piping system. By filling microscopic gaps and irregularities in flange surfaces, these gaskets hold the pipes in place under all pressures, preventing leaks.

Is a Flange Gasket the Same as a Non-Asbestos Gasket?
No, flange gaskets are not the same as non-asbestos gaskets. While both involve sealing properties, flange gaskets are primarily made from rubber, silicone, metals, or composite materials. Non-asbestos gaskets, on the other hand, do not contain hazardous asbestos. Although non-asbestos gaskets can be used as flange gaskets, they may also serve other purposes incompatible with sealing flanges.

In summary, flange gaskets are essential components that enhance operational efficiency and safety in various industrial applications. Their proper selection, installation, and maintenance contribute to leak-free piping systems.
