About the product

In stainless steel tongue and groove flanges, the tongue flange is manufactured with a machined raised ring. on his face. Grooved flanges are manufactured by machining matching recesses into their surfaces. It is important to make waterproof connections. It is important that the faces of these flanges match. The sealing surface of a tongue-and-groove flange has a structure in which the seal is inserted into a groove in the tongue-and-groove surface.The tongue and groove surfaces of these flanges must be aligned with each other. 

For tongue flange surfaces, a raised ring is machined into the flange surface, while a suitable recess is machined into the corresponding grooved flange surface. A tongue and groove cover is standardized for both large and small tongue and groove flanges, and unlike tongue and groove flanges, the inner diameter of the groove and tongue does not extend all the way to the flange base, so the flange base Retained. Seal inner and outer diameter.

Use of the product

Tongue and groove flanges suppliers are used in a variety of piping systems including oil and gas, chemical, pharmaceutical, and more. Suitable for use in applications where strong, leak-free connections are required, such as high-pressure pipelines and corrosive environments. The flanges are also easy to install and can be used with a variety of gasket and bolting options.

Advantages of tongue and groove flanges

The seal in the groove of this flange is not extruded, resulting in the smallest compression area and uniform sealing

Since the seal does not come into direct contact with the medium, it is hardly affected by corrosion of the medium or intrusion of the pressurizing.

Narrow sealing surface requires less screw force and is suitable for high pressure applications with stringent sealing requirements such as: Under high pressure, flammable, explosive, toxic media and in other cases.
