Precision Polymer Engineering (PPE), a manufacturer of molded elastomer seals, has announced that SECC Oil and Gas, a supplier of couplings and connectors to the oil and gas industry, has installed its Perlast G75LT and G90LT O-rings in a patented pressure-balanced disconnect system for subsea operations.
Seals made from PPE’s Perlast ICE G75LT and G90LT materials have been developed to maintain a bubbletight seal even under the low temperature, high pressure environments associated with deep water drilling and production. They have undergone testing and been proven to perform at pressures of up to 15,000psi and at temperatures ranging from -18⁰C to 121⁰C. The elastomer’s low glass transition temperature ensures that the seals maintain their elasticity despite high working pressures, forming an effective seal even in the presence of aggressive and corrosive substances often encountered in oil and gas exploration.
"SECC approached us with a unique challenge, a high performance elastomer material which could continue to operate upon exposure to low temperatures and high pressures,” said Steve Jagels, PPE’s global market manager for oil and gas. "The Perlast G75LT and G90LT O-rings were specially designed to operate at the low temperatures associated with deep water production, while also exhibiting high resistance to chemicals such as aromatic hydrocarbons, water and sour gas.”
