Insulating Materials

Flange insulation kits for metallic pipelines are available in two types for all flange sizes and pressure ratings. Flange insulation kits are commonly installed at the end of a pipeline to electrically isolate the pipe for other buried foreign metallic structures and plant earthing systems, therefore, limiting the amount of cathodic protection current required to protect the pipeline. For protecting insulating flange kits from lightening or fault current suitable spark gap (safe or expulsion proof) should be used.
