This job was for an existing customer who phoned in a panic; they were having new overhead heaters installed but found out at the last minute that the installing company would not connect to the gas supply. Time was of the essence as the new crop of chicks were expected in less than a week. Fortunately the existing internal pipework was reuseable with some modification. The 2nd stage regulator required replacing (new one fitted as in the picture) which was pretty straightforward. On the Saturday morning, everything was tested and signed off - time to see whether the heaters worked. After a couple of false starts they were all working satisfactorily. Another satisfied customer.
In order to comply with HSE requirements, the client instructed us to upgrade all underground gas services at 6 farms. We provided a "turnkey" service, including all trenching, pipelaying and ground reinstatement. This was completed to tight schdules during the limited empty periods on each farm.
This is an existing lodge development, with gas originally being supplied from 47kg cylinders. We were instructed to "retrofit" a piped system and central gas storage, enabling each lodge to enjoy gas via a meter. Phase 1 (25 lodges)has been completed, and Phase 2 (52 lodges) has now been started.
This wasa two stage development of a redundant quarry. The holiday homes are stone built and finished to a luxurious standard. For the first stage (8 homes) we laid a 32mm polyethylene ring main with 25mm service spurs to semi-submerged meter boxes. For the second stage (23 homes) a 63mm main was laid, with service spurs to meter boxes.LPG supply is from 4 x 2000 litre LPG vessels.

The offices are conversions of redundant farmbuildings set around a quadrangle, with the original farmhouse offset to one side. We laid 63mm/32mm polyethylene main underground supply pipes with 25mm service spurs to semi-submerged meter boxes. LPG supply is from 3 x 2000litre vessels.
This refuelling installation is part of a trial development, whereby diesel fuel is supplemented with an accurate proportion of LPG to achieve improved power and economy, according to the equipment suppliers.
The existing underground pipework on both sites from the LPG storage vessels to point of entry at six sheds was 15+ years old, of galvanised metal pipe. The client was concerned that, given the age of the pipe, there might be future issues with soundness.
We installed new 32mm/25mm MDPE polyethylene pipework, using Fusion welded joints. We also took the opportunity to renew all second stage regulators.
During excavation of new trenches, it became evident that the old metal pipe had not been wrapped with any protective coating (Denso) and there was evidence of severe corrosion that could have affected the integrity of the pipework in the near future. The new systems are now complete.
We installed LPG storage vessels, undergound service pipework (63mm/25mm MDPE polyethylene) and post-mounted meter boxes. Owing to space restrictions, a three-stage pressure system was used.
Situated in the Lake District National Park, this site required the use of centralised underground LPG storage vessels, and semi-submerged domestic meter boxes.
The client has several sites with current LPG installations. Aware of their obligations under the Pressure Systems Safety Regulations 2000, we were contracted to undertake soundness testing. All systems were tested, and soundness certificates issued.

As an aid to safety, the old internal gas line was capped off, and a new external main supply installed. The heaters were then connected via individual branch supplies, thus keeping internal pipe runs to a minimum.
