Flat Face Flanges require which type of gasket?

Flat face flanges require a full face gasket to ensure an effective seal. This type of gasket provides a complete surface area that covers the entire flange, creating an even distribution of pressure when the flanges are bolted together. The design helps to fill any gaps and irregularities between the flanges and enables the full contact needed to prevent leaks.

Using a full face gasket is especially important for flat face flanges because they do not have raised sections to support the gasket, making uniform coverage crucial. This type of gasket supports the full area of the flange, allowing for a secure connection that can withstand the operating pressures of the piping system.

In contrast, other gasket types like spiral wound or jacketed gaskets may not provide the necessary surface contact for flat face flanges and are better suited for different flange configurations. Understanding the specific requirements for flange types and gasket applications is crucial for ensuring the integrity and safety of piping systems.
