Gaskets

Kit 5X series

Insulation kit is used to guarantee the electrical insulation between two flanges, in this way we can prevent electrochemical or galvanic corrosion process. It is used in order to prevent contact between two materials with different electrical potential, without modify with the flanges’ tightening. It is suitable for flanges with rating up to ANSI 2500 and API 10000.

Flanges and bolts insulation is guarantee by sleeve and washer. The kit are composed by:

• insulation gasket composed by a Aisi 316L Camprofile type CX core with insulating coating, an insulating layer (MICA on external and TEXLON® on internal) on both sides on which it install two energized lip seals (PTFE/Elgiloy)
• an insulation sleeve for each bolt (G11)
• a couple of insulating washers for each bolt (Inconel 625 with insulating coating) blue.
• a couple of insulating washers for each bolt (Inconel 625 with insulating coating) grey.

Application

Cathodic flange insulation, prevent electrochemical or galvanic corrosion process, coupling between different type of flange (i.e. Ring Joint and Raised-Face flanges), minimize the fluid stagnation, the flow turbulence and erosion between flanges.
