We carry out all aspects of gas testing and purging, from light commercial to large industrial systems.
Our team at Northwest Heating Services Ltd are fully trained, Gas Safe registered and have the skills to carry out a gas purge and test on commercial, industrial and plant gas lines while following all safety guidelines.
Tightness testing is a safety critical process carried out on existing pipe work to ensure your gas pipe work and installations are in a sound condition and safe to use. The test is carried out at a set pressure as per GSIUR 1998 using calibrated equipment to monitor any loss in pressure no matter how small and rectify as necessary.
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.
The purging of commercial & 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 & safe working systems. This procedure would then ensure that any decommissioned pipe work is safe to be dismantled or left open to the atmosphere without constituting a danger.
The purging of commercial & 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!
