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:
