Flange insulation sets
Using isulation sets can prevent cathodic or galvanic corrosion of flanges or pipes. For this, ERIKS offer products from Pikotek for DIN, API and ANSI flanges. They are suitable for low as well as high pressures. By using special materials there are no problems with breakages of underlying rings.
| Gaskets type | RX® type | Description |
|---|---|---|
 | PGE-E | The Pikotek PGE is a non-critical service gasket designed for electrical flange isolation and/or general sealing applications. The type PGE-E is a version were the gasket is centered between on bolts (boltholes). This gasket is suitable for use in raised-face flanges up to ANSI class 600 (or equivalent) and is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired. The design of the Pikotek PGE gasket incorporates patented overlapping and offsetting seal grooves. The purpose of this design is to break each layer of laminate within the gasket itself thereby creating a barrier through which fluid and/or gas cannot migrate. The sealing element can be any elastomeric material as well as more sophisticated Spring-Energized Teflon® lip seals. As a result of this advanced gasket design, maintenance free flange isolation and flange face corrosion mitigation are achieved economically. |
 | PGE-F | The Pikotek PGE is a non-critical service gasket designed for electrical flange isolation and/or general sealing applications. The type PGE-F is a version were the gasket is centered between the bolts. This gasket is suitable for use in raised-face flanges up to ANSI class 600 (or equivalent) and is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired. The design of the Pikotek PGE gasket incorporates patented overlapping and offsetting seal grooves.

As a result of this advanced gasket design, maintenance free flange isolation and flange face corrosion mitigation are achieved economically. |
 | VCS | The VCS gasket consists of a PTFE (Teflon®) spring-energized face seal, or an elastomeric o-ring, seated in an insulating laminate, which is permanently bonded to a high-strength metal gasket core. Due to its unique pressure activated sealing mechanism, the gasket requires far less bolt stress to seal than any other gasket. The VCS gasket inner diameter is exactly matched to the flange bore to eliminate turbulent flow and flange face erosion/corrosion. The seal elements are replaceable in the reusable gasket retainer. |
 | DDW | The type DDW exists of a central gasket from a phenolic material in the same shape of a Ring Type Joint. The complete set consits of a gasket, 2 insulation washers (phenolic) and 2 metal washers per bolt and a en Mylar sleeve. Only for ANSI B16.5 ring joint flanges class 150 t/m 1500lbs. Application is protection against cathodioc or galvanic corrosion. |
