Garlock Pipeline Technologies (GPT) the manufacturer of critical pipeline sealing and electrical isolation products has announced the unveiling of EVOLUTION®. The next generation of isolation gaskets, it features easier installation, tight sealing, high-temperature operation, no permeation, hydrotesting isolation, fire-safety, and chemical-resistance.
Featuring a thinner, 1/8” design, EVOLUTION minimizes 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 (a GPT proprietary material) 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 it has demonstrated virtually no permeation or degradation, eliminating this costly problem.
It provides the highest pressure rating of any isolating gasket available. Unlike GRE gaskets, which are prone to delamination, it has no laminations and as a result, can better withstand high-pressure environments.
Rated to 500°F (260°C), it can operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.
