ASME B16.5 Tongue and Groove Pipe Flanges (T&G)
Skyland Tongue and Groove Flanges (T&G) must be used in matched pairs: one flange features a raised circular ring (Tongue) while the mating flange features an identical matching depression (Groove). The gasket is fully enclosed and protected inside the groove, preventing gasket blowout under extreme pressures and eliminating fluid contact with outer atmosphere.
Manufactured to ASME / ANSI B16.5 standards in Large and Small Tongue & Groove designs
Pressure Classes: Class 150, 300, 600, 900, 1500, and 2500 LBS
