Current method & challenge

The transformer manufacturer was using cork gaskets, but due to gaps left between the flanges he was facing the following challenges.

• Precut gaskets were not able to tackle the surface irregularities in the flanges.
• Cork gaskets deformed over time leading to creation of leak paths.

This led to a high number of service requests due to leakages at the customers end.

Solution

Oil tank flange is cleaned with a solvent based cleaner. LOCTITE SI 5910 is uniformly applied. The top cover of the oil tank is sealed, and bolts are tightened.

Result

• 50% lower service request.
• No need to maintain large inventory of different gasket sizes.

Additional benefit

Reduction 50% in
service requests Reduced power loss
