High pressure gas purge – MCSBS

In order to ensure the efficient and effective functioning of a Hamworthy Gas Fired Water Heater with an onsite gas carcass running at 35mb (not common place), the CH Systems team opted to decommission the gas line to fit a local Governor serving the water heater. Once the pipework modifications were carried out we returned the pipework into service and conducted a tightness test as well as a purge back to Natural Gas.

Decommissioning, tightness testing and purging are carried out on existing or new gas pipework installations to ensure that the industrial and commercial gas pipework is safe for use, or continued use, and will not be rendered a hazard or cause an unsafe situation. The high pressures produced by this particular system required both experience and skill on the part of our engineers. See the below pics for an idea of what the job entailed:

Gas Purge Gatwick South Terminal

CH Systems was commissioned to purge the gas main that previously served the McDonald’s restaurant in the South Terminal at Gatwick Airport. The gas pipe ran about 30m in length and upon completion of the work, we were able to issue the necessary certification of safety.


Trinity School, Croydon

CH Systems carried out a decommission, strength test and purge to gas at Trinity School in Croydon following the discovery of a leak in the below ground pipework. We are glad to say that the job was completed safely.
