GAS PURGING & TESTING
SERVICES
We would advise as best practice that all gas pipe work is inspected and tested annually during your regular gas appliance servicing. Often this is a requirement of your building insurance to validate the policy.
​
​
Purging is carried out to avoid the possibility of an explosive air/gas mixture existing or forming in consumer piping, appliances or confined spaces. Purging is defined as the displacement of air or an inert gas by a fuel type by air or by other means.
​
Tightness Testing
New commercial and industrial pipe work should undertake a Strength Test (STP) which is carried out above the normal operating pressure to identify any construction faults with the new pipe work installation.
​
Purging Decommissioning
The purging of commercial and industrial gas pipe work from gas to air is carried out to displace the combustible gasses with an inert mixture via a series of calculations, purge stack and safe working systems. This procedure would then ensure that any decommissioned pipe work is safe to be dismantled or left open to atmosphere without constituting a danger.
​
Purging Commissioning
The purging of commercial and industrial gas pipe work from air to gas is to ensure the perfect air/gas mixture is passed through the pipe work without causing any hazards such as stratification or enveloping within the gas lines. The incorrect mixture at the incorrect rate will lead to appliance failure, explosive ignition, etc!
