What Is a Tongue & Groove Flange?
A tongue & groove flange is more than just a component; it is a critical part of industrial piping systems designed to ensure safety, efficiency, and durability. These flanges come in pairs: one with a raised ring (tongue) and the other with a matching groove. This design ensures self-alignment and protects the gasket from blowout, making them suitable for high-pressure, flammable, or toxic fluid services.
Widely used in high-pressure environments, it plays a vital role in oil & gas, chemical, power, and water treatment industries for isolation, inspection, and pressure testing purposes.
Pro Tip: Tongue & Groove Flanges are often designed to work seamlessly with Welding Neck Flanges in critical piping applications to ensure maximum system integrity.
