Garlock Pipeline Technologies (GPT), one of the leading manufacturer of critical pipeline sealing and electrical isolation products, has launched EVOLUTION™ featuring easy installation, tight sealing, high-temperature operation, no permeation, hydro testing isolation, fire-safety and chemical-resistance
Featuring a thinner, 1/8” design, EVOLUTION aims to minimises the difficulties often encountered when attempting to install thicker isolating gaskets. The full-coating encapsulation allows the gasket to be hydrotested and left in the pipeline with the same isolation properties as before it was tested.
EVOLUTION's coating is extremely abrasion and impact resistant while providing chemical resistance to H2S, steam, CO, CO2 and other chemicals often found in oil and gas pipelines. This fully encapsulated coating also prevents the need for expensive exotic cores, as it eliminates contact to exposed metal.
The EVOLUTION gasket features the highest tightness parameters for any product available in the market today. With demands placed on the oil and gas industry to improve leakage rates, the increased levels of tightness achieved will exceed requirements and result in greater joint integrity.
An acceleration in H2S levels as operators drill deeper and more aggressively causes traditional GRE products to become vulnerable over time. Through extensive testing, EVOLUTION has demonstrated zero permeability or degradation, eliminating this costly problem.
According to GPT, 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 260°C, EVOLUTION aims to operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.
Tim Hurley, senior global product manager at GPT, said, “EVOLUTION was designed to take the best available technology for pipeline isolation and incorporate all of these benefits into one comprehensive product.”
As with any GPT high-pressure isolation gasket, EVOLUTION features pressure energized seals, a pressure activated seal, a fire safe Inconel 718 c-ring, built to match pipe bore, a short moment arm, moisture and humidity resistance, zero creep relaxation and a 316LSS core.
