Evolution® Isolation Gaskets

EVOLUTION® Isolation Gasket - The Future of Flange Isolation. Available Soon

***** AVAILABLE SOON *****

EVOLUTION® is a patent pending product that is the first of its kind to be a fully encapsulated isolating gasket. The thinner, 1/8” (3mm) design minimizes the difficulties often encountered while attempting to install thicker isolating gaskets. The total encapsulation allows the gasket to be hydro-tested and kept in the pipeline with virtually no loss in isolation properties.

This innovative gasket is coated using a GPT proprietary material designed specifically for the oil and gas industry that is extremely abrasion and impact resistant. The coating is also chemically resistant to attack from H₂S, steam, CO, CO₂, and other chemicals found in oil and gas pipelines.

EVOLUTION® has passed API 6FB fire testing in multiple sizes and pressure classes and has a considerable increase in operating temperature over GRE products. Furthermore, EVOLUTION® does not have the permeation issues or chemical attack that plagues GRE gaskets.

Under harsh conditions, gaskets made from GRE may be vulnerable to chemical attack, blowout, thermal attack, hydrolysis and emissions —all of which can have serious consequences. EVOLUTION® is different. Its revolutionary materials and design provides industry-leading resistance to leakage and flange corrosion, as well as unprecedented levels of fire safety.

EVOLUTION® provides the highest pressure rating of any isolating gasket available. Unlike GRE gaskets, which are prone to delamination, EVOLUTION® has no laminations and as a result can better withstand high-pressure environments.

Rated to 500°F (260°C)*, EVOLUTION® can also operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.

FEATURES AND BENEFITS                    

316L Stainless Steel Core

  • Only three millimeters (1/8 inch) thick
  • Thinner profile helps make installation easier and more accurate

Proprietary Coating

  • High dielectric strength
  • Eliminates expensive exotic cores due to the fully encapsulated coating
  • Rated to 500°F (260°C)

*For higher temperature applications, please order MICA sleeves and MICA washers.

Inconel 718 C-Ring

  • Fire safe - provides the added security of knowing that the gasket has passed the API 6FB, 3rd Edition Fire Test in multiple sizes/classes
  • High pressure - highest pressure rating of any isolating gasket

PTFE ID Seal

  • Resistant to typical oil and gas chemicals, in particular H₂S, CO, & CO₂
  • Impermeable seal and encapsulated carrier eliminates the need to replace gaskets following hydro-testing
  • Sealing is as low as an average of 3ppm methane in an industry standard Fugitive Emission Test

Handle

  • The handle found on the EVOLUTION® allows each gasket to be holiday tested during manufacturing to insure strong isolation performance in the field
  • Helps ensure accurate alignment during installation
  • Provides traceability and identification for the product

APPLICATIONS

  • Fire-safe 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
  • Mating mismatched ring-joint to raised-face flanges (EVOLUTION® 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 and other aggressive hydrocarbon media are present
  • Eliminate turbulence and flow-induced erosion between ring-joint (RTJ) flanges.
  • To seal between flanges subjected to vibration/cavitation (i.e., compressor stations).
