What is Flange Insulation Gasket Kit?
The most common problematic area for a Piping/Pipeline System design is flanges. So we have to be doubly sure to seal it properly to prevent flange leakage. At the same time, It must also be insulated cathodically so that stray currents which are known behind the undue corrosion and eventual metallic breakdown be prevented. Insulating gasket sets or Flange insulation kits play an important role in such cases.
They are designed for electrically insulating the flanges.
They act as an insulator between dissimilar metallic flanges.
Also, they are used to isolate sections of pipework (dissimilar metals) electrically in the cathodic protection systems; thus preventing the electrostatic charge flow along the pipelines as they remove the possibility of galvanic cell system creation.
Major Applications of Insulation Gasket Kits
Insulating gasket kits can be used in all such places where galvanic corrosion protection and electrical insulation are needed. Common Application areas are piping/pipeline systems with seawater environments, offshore installations, chemical installations, oil refinery pipelines, etc.
Components of Flange Insulation Gasket Kit
Each flange insulation Kit constitutes of
one central flat or oval section gasket,
one insulation sleeve per bolt and
two insulating steel washers per bolt and
two plated steel washers per bolt.
All these components are produced using special materials possessing chemical stability, dielectric properties, and low water absorption so that the purpose is solved. The full sets are packed individually and labeled clearly mentioning the flange size, rating, type, and material combination. Insulation kits are generally available to 24 inches, but custom-made higher nominal sizes can be produced on the requirement.
