Garlock管道技术（GPT）–关键管道密封和电气隔离产品制造商– has announced the unveiling of an upgraded offering to its 演化®.
The next generation of isolation gaskets, 演化 is now available in sizes from 0.5 in. nominal pipe size (NPS) to 36 in. NPS, in addition 演化 is offered as a Full Face (Type E) gasket.
The 演化 Isolating gasket which was launched a year ago marked a significant step change in the design and manufacturer of Isolation gasketing. Designed to meet the ever the increasing demands of oil and gas transmission, today and in the future.
演化 isolates flanges to prevent galvanic corrosion and to optimise cathodic protection systems as well as providing unparalleled sealing performance ensuring greater joint integrity.
An acceleration in H2S(sour gas) levels as operators drill deeper and more aggressively causes traditional GRE products to become vulnerable over time. Through extensive testing 演化 has demonstrated virtually no permeation 要么 degradation, eliminating this costly problem.
Rated from -300 °F(-184 °C) to 500 °F (260 °C), 演化 can operate under high and cryogenic temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.
As with existing GPT high pressure isolation gaskets, 演化 features: pressure energised seals, a fire safe Inconel 718 c-ring, built to match pipe bore, a short moment arm, moisture and humidity resistance, zero creep relaxation, additional benefit of easier installation and a 316LSS core.
