Dichtomatik Ltd has extended their stock range of sealing components, including specifically designed items for the high pressure/high temperature (HPHT) conditions. High performance seals such as Viton® fluoroelastomers have been used in extraction, refining and upgrading industries for over five decades.
Typical installations have successfully solved critical sealing problems where elastomers such as nitrile or EPDM have failed to provide an effective long-term sealing performance. Later developments have seen the introduction of DuPont™ Kalrez® perfluoroelastomer parts which can withstand operating conditions involving attack from a range in excess of 1800 chemicals, solvents and plasmas, even where, incorporating working conditions up to 327°C (620°F) are utilised.
Viton® outlasts nitrile rubber and other general-purpose elastomers and is ISO 9000 registered worldwide. The ability of this product to withstand both high heat and low temperatures as well as aggressive fuels and chemicals, makes it an ideal medium for the production of protective coatings as well as O-rings, together with gaskets in a wide variety of custom shapes and sizes.
The Kalrez® parts are particularly suitable for HTPT seal applications, providing long-term performances over a wide spectrum of oil and gas industry working requirements. These perfluoroelastomer (FFKM) parts are highly resistant to aggressive chemicals and solvents, including sour multi-phase fluids.
