Flange Insulation Kit

The growth of long distance underground pipeline systems increases the need for special protective measures against external corrosion. The aggressive nature of the ground, the effect of stray currents from nearby installations and the damaging potentials created by electro chemical reaction in the earth have a deterioratory effect on pipelines and demand reliable long term corrosion protection measures. Experience during recent years has shown that the cathodic protection together with a high grade passive corrosion protection by application of coating on the pipeline, provides a most efficient and economical solution.

Insulating joints at the flange points in a pipeline have a very important part to play in reducing the cost of the cathodic protection systems.

Application of Flange Insulation kits

• 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.
