High pressure gas purge – MCSBS

/in , /by

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:

The CH team was briefed to fit two new Hamworthy Wessex ModuMax mk3 boilers (alongside the existing Hamworthy boilers) in a recent Plant Room upgrade for a national supermarket Chain in Walthamstow.

Our welders had to fabricate a number of spool pieces to enable us to connect to the Imperial Table D flanges. We also had to fabricate a 6-inch header to which all 4 boilers then connected on to. The gas run on this installation was all carried out in 108mm Geberit Mapress Stainless and was slightly challenging as we had to run this on the underside of the first floor slab; the work was all carried out on a SkyJack SJ19, which greatly helped in reducing the installation time.

The heating coil that serves the shop floor air handling unit was also changed over during the course of the project and we’re happy with the final result.
