Purging & Leak Detection

Gas Purging

Purging is a process used in many industries to describe displacing an unwanted substance (usually air) from a vessell/pipework.

Generally purging is used to replace an oxidising or reactive gas with an inert gas typically in engineering or food production industries.

As an example, nitrogen is often used to purge brewery piping systems to prevent oxygen causing product to degenerate.

Pressure Testing & Leak Detection

Pressure testing involves building pressure within a vessel to a specified level using a purging gas to ascertain vessel integrity and leak resistance. Leak detection can be measured by pressure drop or specialist mixed purging gases incorporating an easily detectable element such as hydrogen.

We supply a range of high quality gases for these applications
