Leak Testing

Due to the small size of the molecule and its inert properties, helium is often used as a tracer gas for leak testing of pipelines. A leak of hydrocarbons and other flammable gases may have fatal consequences on platforms or similar installations.

Purging / Inerting

To remove undesirable gases from pipelines and tanks nitrogen is used to purge the systems. Especially residual amounts of hydrocarbons may create possible hazards and must be displaced prior to shutdowns and maintenance work. Also at the commissioning stage of plants air and other unwanted gases have to be removed, and nitrogen is used for this.

Calibration of Gas Analyzers

Praxair can supply the most accurate calibration gases for the gas analyzers in the oil and gas fiscal measurements. As the energy content of natural gases is dependent on the composition, the gas analysis is paramount in the determination of the energy value, hence the sales price of the gas. Praxair has accreditation from the Norwegian approving body that proves our capabilities in the production and analysis of the calibration gases.
