CUSTOMIZED FLANGE SA182 F304 STAINLESS STEEL TONGUE / GROOVE FACE

The stainless steel tongue and groove flange are one type of flanges that come in a pair. One piece of the pair has a tongue like extrusion poking out of the flange and the other piece of the pair has a matching grove on it. So when fitted together, outside the pipes that are being connected, the flange tongue gets in place inside the grove. To make the connection even secure, a gasket could be added between the tongue and grove. This mechanism assures minimal leakage and maximum fitting between the pairs. So this mechanism makes the connections perfect.

Tongue and Groove faces of this flanges must be matched. One Tongue flange face has a raised ring machined onto the flange face while the mating grooving flange has a matching depression machined into it’s face.Tongue-and-groove facings are standardized in both large tongue and groove flange and small tongue and groove flange, different from male-and-female in that the inside diameters of the groove and tongue do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. Our offered Tongue and Groove flange applications are commonly on pump covers and Valve Bonnets.

Tongue and groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.General flange faces such as Tongue and Groove flange shall never be bolted together because of there contact surfaces do not match and there is no tongue and groove flange gasket that has one type on one side and another type on the other side.
