Electrical insulating flange gaskets are a family of gasketing devices which, along with insulating sleeves and washers, prevent electric current from passing across flanges. Failures at high pressure with conventional types of this gasketing device on the North Slope of Alaska led a major Oil and Gas company to develop an improved high pressure electrical insulating flange gasket. In 1980, this improved gasket was tested along with conventional types. The results of this testing, and the subsequent eight years of actual application, verify the utility of this improved gasket design.
