China Flange Insulation Kits Manufacturer – Protecting Pipelines & Equipment

A flange insulation gasket kit is a complete set including an insulating gasket, insulating sleeves, and insulating washers. It is installed between flanged pipe joints to prevent electrochemical corrosion caused by stray currents, galvanic reactions, or cathodic protection systems. It also maintains the integrity of the pipeline's cathodic protection.
