Pikotek® PGE System Isolating Gaskets/Kits

PRODUCT TYPE: Flange Isolation-Pikotek

The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating gaskets.

Pikotek® PGE™


The Pikotek® PGE™ is a low-pressure service isolation kit designed for electrical flange isolation and/or general sealing applications

The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating gaskets. The unique design of the PGE™ system 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 PTFE lip seals. As a result of this advanced seal design, maintenance-free flange isolation and flange face corrosion mitigation are achieved economically. Depending upon the sealing element selected, the PGE™ is rated for most hydrocarbon and water service applications.

This gasket is suitable for use in raised-face and flat-face flanges in ANSI Class 150, 300 and 600 service (or equivalent). In addition to providing electrical isolation, the gasket is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.




Features and Benefits

  • Extremely high reliability sealing and insulating for all critical services
  • Seals and insulates at all pressures up through ANSI 2500# and API 10,000#
  • Withstands severe service conditions, including large bending moments, vibration, temperature, and pressure cycling
  • Withstands corrosive environments, including high concentrations of CO2, H2S, produced water, etc.
  • Outstanding isolating properties for cathodic protection, galvanic corrosion, and other pipe system isolation needs
  • Pressure activated for reliable sealing and eliminating costly leaks
  • Precisely sized to the bore to protect flange faces and prevents turbulent flow at flanged connections to mitigate media-induced corrosion and flow-induced erosion
  • Eliminates microbially induced corrosion (MIC)
  • Mitigates galvanic corrosion in dissimilar metal flanges
  • Insulating Kits (sleeves and washers) always include high strength double washers and full-length sleeves for maximum assurance against short circuits
  • High strength laminate material resists failure due to excess compression (i.e., over tightening bolts)
  • Spring energized PTFE seal provides radial load and encapsulation in the seal groove to eliminate cold flow
  • Available to match any flange specification (ANSI, API, BS, DIN, AS, others)
  • Can seal mismatched RTJ Flange with Raised Face Flanges
  • Re-usable
  • Easy installation, make up and removal The rigid construction helps facilitate installation. Low required bolt loads. Less make-up force is required resulting in less flange and bolt stress. Self-aligning and centering No special tools required.

Applications

  • Flange insulation in conjunction with cathodic protection
  • Insulation between dissimilar metals to prevent galvanic corrosion
  • Wellhead isolation from inter-connected flow lines
  • Valve connections
  • Christmas Tree connections
  • Pump connections
  • Compressor connections
  • Tanks and heat exchangers with sacrificial anodes to increase anode life
  • Mating mismatched ring-joint to raised-face flanges (VCS will seal in ring-joint, raised-face and flat face/slip-on flanges)
  • Eliminate fluid trap corrosion between ring-joint (RTJ) flanges where high concentrations of CO2, H2S, other aggressive hydrocarbon media are present
  • Eliminate turbulence and flow-induced erosion between ring-joint (RTJ) flanges.
