Flange Insulating Gasket Kits or Insulation Kits provided by Goodrich Gasket Pvt Ltd consists of:
1. Phenolic sheet/neoprene faced Phenolic resin laminate gasket [Type E & F only] between the flange sealing aspects.
2. Phenolic laminate bolt arms.
3. Double insulating washers per bolt.
4. Two sheeted mild steel washers per bolt. [Stainless steel washers accessible upon special request].
Utilization of different metallic flanges with a conductive gasket physical aided by an appropriate electrolyte sets up a galvanic cell, corroding the anodized metal. It is here that the insulation kit or rim insulating gasket kit comes into exercise by protecting the pipeline flange deterioration. The insulation kit is also applicative for electrically isolate flange joints, precluding the flow of electricity charges on the pipeline.
The different kinds of flange insulating gasket kits or insulation kits we offer are:
|TYPE||CONSTRUCTION / FUNCTION||SUITABILITY|
|Goodrich Insulation Gasket for Type F Raised face flanges||Employs a central gasket that locates within the bolts.||Ring grooved, Flat & raised face flanges.|
|Goodrich Insulation Gasket for Type E Full face flanges||Minimizes the ingress of conductive foreign matter between the portions of the flanges outside the elevated faces & cut down the risk of bridging.|
|Goodrich Insulation Gaskets for Type D ring joint gaskets||Insulating oval subdivision ring joint will set into a standard RTJ flange ring groove.|
A self adherent tape covered around the external diameter of the flange gives absolute electrical insulation and hindrance of immersion of foreign matter. Phenolic material utilized in these insulation kits by our company offers superior insulation and corrosion resistivity.
Type E & F proffered by Goodrich Gasket necessitates the bore of the gasket and the pipe to be equivalent to preclude any foreign matter from compiling in the annular gap between bore of the pipe and bore of the gasket, thus precluding bridging.
Some particular properties of Phenolic gaskets are:-
|Maximal axial compressive stress||45700psi [315MPa]|
|Axial electric capability in oil @ 1900F||58kV/in [23kV/cm]|
|Maximal operating temperature||2500F|
|Minimal operating temperature||-760F|
The insulation kits are of all-inclusive use in offshore installations, hydrocarbon service, chemical installations, sea water environments, oil refinement pipelines requiring electrical insulation and galvanic corrosion protection.
