Interested in the Evolution Isolation Gasket? Get in touch!
Conditions are changing. As we drill deeper and utilize enhanced recovery methods such as thermal and CO2 injection, we are exposing the products in our pipelines to greater concentrations of harsh chemicals, higher temperatures and higher pressures. In addition, it is estimated that 40% of the world’s remaining gas reserves are sour, and CO2 and/or H2S content within these wells averages 10% or more. Maintaining pipeline integrity and keeping emissions in check has never been more important. Yet, traditional pipeline materials, including gaskets and seals, are not always up to the challenge. That is why we are proud to introduce Evolution, a fully-encapsulated isolation gasket that delivers the impermeable performance needed to prepare any flange for the increasing risks found in today’s oil and gas industry.
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.
* When used with Mica sleeves and washers
*For higher temperature applications, please order MICA sleeves and MICA washers.
