The sealing environment for down-hole pumps, compressors, valves and pipelines represents some of the most aggressive conditions to which elastomer seals are exposed. Temperatures may range from -50°C to 250°C and pressures may exceed 20,000 psi, creating a physically demanding environment.
Additionally, hydrocarbon based gaseous mixtures present in the process stream often contain hydrogen sulfide and carbon dioxide which at the pressures and temperatures under consideration become highly solvating and reactive to the elastomer. Furthermore, seals in these applications are also exposed to steam, acids, amine inhibitors and alcohols, abrasive muds and rapid pressure changes, all of which are potentially damaging to seals.
