Pikotek Brings a Revolutionary Concept in Flange Isolation with the Evolution Gasket
Pikotek recently introduced their all-new Evolution gasket for multiple applications, including:
- sealing of flanges that are prone to cavitation and vibration
- eliminating flow-induced erosion and turbulence between ring-joint flanges
- eliminating fluid trap corrosion between ring-joint flanges with aggressive hydrocarbon media, including CO2 and H2S
- preventing galvanic corrosion between dissimilar metals
- insulation of fire-safe flange in conjunction with cathodic protection
- mating of mismatched raised-face flanges to ring joints
- wellhead isolation from inter-connected flow lines
- compression connections
- pump connections
- valve connections
- and Christmas tree connections
The EVOLUTION gasket is a fully encapsulated isolation gasket. The patent is pending on this unique innovation. What sets Evolution apart is its thinner design, which enables for more diverse installation applications. Since the gasket is fully encapsulated, it can be hydro-tested and it can remain in the pipeline without losing any isolation properties.
The Evolution gasket features a fully encapsulating coating made from GPT proprietary material specific to the oil and gas industry. This coating makes the gasket:
- impact resistant
- abrasion resistant
- chemically resistant (CO2, CO, steam and H2S)
The Evolution isolation gasket has undergone stringent fire testing in a range of pressure classes and sizes and has been proven to offer a significantly higher operating temperature over GRE products.
Unlike GRE gaskets that have some vulnerabilities, there is no permeation or chemical attack with the Evolution isolation gasket. GRE gaskets often fail under harsh conditions, resulting in emissions, hydrolysis, thermal attack, blowout or chemical attack.
No other isolating gasket offers a higher pressure rating than the Evolution isolation gasket.
Made from three millimetres thick stainless steel, it has a thin profile which ensures easy, accurate installation. The proprietary coating offer high dielectric strength.
The Iconel 718 C-ring has passed the 3rd Edition API 6FB fire test in multiple classes and sizes and has been shown to offer the highest pressure rating of all isolating gaskets.
The impermeable PTFE ID seal and the encapsulated carrier do not need to be replaced after hydro-testing.
The Evolution isolation gasket features a handle that helps enable accurate alignment during the installation process, and carries identification and traceability.
