TONGUE & GROOVE FLANGES

Tongue & Groove Flange, the Tongue Flange is manufactured with a raised ring that is machined into its face. The Groove Flange is produced with a matching depression machined onto its face. In order to have a watertight connection, it is important to match the faces of these flanges. Alloy 20 Groove & Tongue Flanges are self-aligning; they do not come in contact with the inner fluid or gas of the tube or pipe. Instantly, they are free from any corrosion. Nickel Tongue & Groove Flanges are used in the chemical, petroleum and crude oil extraction industry

Frequently Asked Questions: Tongue & Groove Flanges

Q: How do Tongue and Groove Flanges seal together?

A: They are manufactured as a matched pair. One flange has a raised ring (the tongue) and the opposing flange has a matching depression (the groove). This design forces the gasket to remain completely confined, making it physically impossible for the gasket to blow out under extreme pressure.

Q: What is the primary application for Tongue and Groove Flange sets?

A: They are widely used in dangerous, toxic, or highly flammable fluid pipelines where leakage is catastrophic, or in systems subjected to severe vibration and shifting.
