SF6-filled joints for testing

We have not used threaded joints in SF6 gas transformer system except for pressure gauge, quarter inch ball valves and pressure transmitter. Gasket joints gives better leak tightness than treaded joints.•Pipe line materials are tested for Chemical, Physical and Inter Granular Corrosion (IGC) test.
