Overview
Product overview
Tongue and Groove Flanges are indispensable components in industrial piping systems, offering a reliable solution for connecting pipes, valves, and other equipment.
Understanding Tongue and Groove Flanges
Tongue and Groove Flanges feature a unique design comprising two flanges, one with a raised ring (tongue) and the other with a corresponding groove. When bolted together, the tongue of one flange fits snugly into the groove of the other, creating a secure and leak-proof joint. This design ensures optimal alignment and sealing, making Tongue and Groove Flanges ideal for high-pressure and high-temperature environments.
