Oil well production is the most important stage in the lifespan of oil wells, which prepares oil or natural gas for final treatment by releasing hydrocarbons. Separation is usually carried out on the seabed, rather than on the platform of offshore oil wells. In addition to dealing with system pressures up to 1,380 bar (20,000 PSI) and temperatures exceeding 900C(1,650F) in flare stack controls, se...

Spring energized seal is a spring-actuated, pressure-assisted sealing device consisting of a PTFE (or other polymer) jacket partially encapsulates a corrosion-resistant metal spring energizer. When the JST seal is installed in the gland, the spring is under compression, forcing the jacket lips against the gland walls and there by creating a leak-tight seal. The spring provides permanent resilience...
