IK-Group's Flange Sealing Clamp

Flange Sealing Clamp is designed to seal off flange leakages. Dependent on the pressure, clamp can either be delivered as self-sealing unit or equipped with sealant injection system. Sealing is obtained by a compressed rubber seals, enveloping leaking flange surface and (if such option is needed) by injection of sealant.  Proposed sealant is designed to react based on simple fluid dynamics and after the injection it changes its state from liquid to solid, providing required sealing capability.
