PGE Insulation Flange Gasket by Pikotek

The Pikotek PGE Flange Gasket is a low-pressure service gasket designed for electrical flange isolation and/or general sealing applications. This gasket is suitable for use in raised-face and flat-face flanges in ANSI class 150 and 300 service (or equivalent). In addition to providing electrical insulation, the gasket is excellent for electrically isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.

The PGE Flange Gasket was designed to give operators an alternative to ailure-prone phenolic-based insulating gaskets. Based on its construction, the PGE will provide a superior, long-lasting solution when compared to phenolic-based designs. The PGE is available in two configurations: full-face (Type E) and ring style (Type F). Depending upon the sealing element selected, the PGE is rated for most all hydrocarbon and water service applications.

The unique 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.

Advantages & Benefits

• Superior sealing solution for low-pressure (ANSI class 150 and 300) service.
• Pressure-activated seals provide high confidence sealing.
• High-strength laminate material resists failure due to excess compression (i.e., over-tightening bolts).
• Overlapping seal grooves eliminate potential leak/weep path in laminate material and provide stronger structural integrity versus "opposing seal" designs.
• Reinforced laminate retainer material provides excellent insulation for cathodic protection systems.
• Insulating Kits always include high-strength double washers and full-length sleeves for maximum assurance against shorting.
• Gasket is sized to the bore, which protects flange faces from media-induced corrosion and flow-induced erosion.
• Mitigates galvanic corrosion in dissimilar metal flanges.
• Developed from proven Pikotek sealing technology.
• Spring-energized Teflon seal provides radial load and encapsulation in the seal groove, which eliminates cold flow. This seal truly distinguishes the PGE from all other sealing systems.
• Also available with a variety of elastomeric seals.
• Easy installation, make up and removal
  - The PGE easily slips into place.
  - Sealing system results in low required bolt loads. Less make-up force is required,
    resulting in less flange and bolt stress.
  - Gasket is self-aligning and self-centering, quick to install; no special tools are required.
• Maintenance-free, corrosion-resistant design.
