We have created a clean pressure controlling environment, which guarantees accurate results in high pressure testing, which uses aggressive and dirty test media. 

By implementing a chemical / diaphragm seal into the pressure control system, we ensure that equipment used for monitoring & controlling pressure (including pressure gauges, transmitters & switches) delivers a reliable test, as the operating fluid is clean.

There are many different types of chemical seals available on the market but they typically have very limited pressure / temperature ratings and are manufactured from materials that are not compatible with aggressive media such as H2S.

We have designed and supplied a unique special purpose HPHT chemical seal. It was implemented within a HPHT autoclave system, for accurate simulation of downhole sour gas environments.

The chemical seal is rated 1700 bar, with operating pressure at temperatures up to 300°C and the main wetted components are manufactured by Hastelloy C276.
