Product Detail
To limit the extent and cost of cathodic protection current to only those pipes that need to be protected from the main cathodic protection system
To electrically "split up" long pipelines into distinctive cathodic protection systems
To isolate a pipeline to ensure that cathodic protection or stray electricity currents do not cause increased corrosion, or cause a hazard
To isolate piping systems where dissimilar metals are present
To eliminate static loading charge transfer in discharge or loading operations at oil storage terminals
Flange Insulation Gasket Kits are usd to solve the sealing and insulating problems of flanges, and to control losses due to corrosion and leakage of pipelines. They are widely used to seal flanges and control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems.
