Tongue And Groove Face Flanges

The sealing surface of the tongue-and-groove face flange is composed of a tongue face and a groove face, and the gasket is placed in the groove. Applicable gaskets include: metal and non-metal flat gasket, metal wrapped gasket, spiral wound gasket, etc.

Like the concave and convex flange, the tenon and groove flange gasket will not be squeezed out in the groove, the compression area is the smallest (only 52-68% of the Flat Flange and the concave and convex flange), and the gasket is evenly stressed. Because the gasket is not in direct contact with the medium, the medium corrosion effect and the pressure mechanism penetration effect are minimal, and can be used in high-pressure, flammable, explosive, toxic media and other occasions with strict sealing requirements. The sealing face gasket is well aligned during installation, and it is difficult to process and replace the sealing face gasket.
