Pipework Inspections Testing and Purging

We Handle All Pipework From Start To Finish

Pipework Inspection And Testing to IGE/UP/1 (and 1A)

To ensure that your installation pipework is maintained in a safe condition, as detailed in the current Gas Safety (Installation and Use) Regulations, we advise that all pipework installations be inspected and tested on an annual basis, normally at the same time as the annual appliance service.

However, some larger premises require specialised service engineers to undertake strip down work on steam boilers etc. In these circumstances, Comgas can offer a Pipework Test and Inspection as a ‘stand alone’ service.

Pipework Purging And / Or Decommissioning

Comgas have vast experience in the purging and/or decommissioning of gas pipework.

Our engineers have purged several large high profile sites across Scotland. Some of these sites include: –

  • Edinburgh Airport
  • Robert Gordon University, Aberdeen
  • Scottish And Newcastle Brewery, Fountainbridge, Edinburgh
  • Ibstock Brick Factory, Bellshill
  • IBM Factory, Greenock

In addition, Comgas has purged several large high profile sites across Scotland. Some of these sites include Edinburgh Airport and Robert Gordon University. Comgas Ltd has also commissioned some fantastic new buildings including the new Motherwell College and the new Play Sports facility in East Kilbride.

On conclusion of the purging / decommissioning, a certificate will be issued detailing all recorded readings. This is your assurance that the work has been completed to a high standard, following rigid guidelines set down in IGE/UP/1 (and 1A).

What Is Involved In Pipework Inspections?

Many people think that it is just their appliances that need to be checked but any non-domestic premises should also have the pipework inspected and tested at regular intervals as per the gas safety regulations. All gas appliances in your property need to be safety checked by a Gas Safe registered engineer annually and serviced according to manufacturer’s instructions. Any appliance left unchecked could leave you at risk of carbon monoxide poisoning. It’s an extremely good idea to have your gas pipework inspected at the same time as having a gas safety check, every year – and it’s the law if you’re a landlord.

What Is Pipework Testing?

Comgas regularly test pipework newly installed by Mechanical installation companies such as CHES, FES, Castle Building Services. These companies us Comgas and the team’s expert knowledge and experience to ‘sign off’ the pipework and know that they can trust the professional judgment.

What is Pipework Purging?

This is often linked to testing but not always. Purging is undertaken during the commissioning stage. For example, purging is done on new pipework AFTER the pipework has successfully passed the tightness test it needs to be safely purged following the procedures laid out in IGE/UP/1 (or1A). This is a critical procedure as it is imperative that an explosive mixture of gas and air is not left within the pipework

Ok, What Is Purging For Decommissioning Purposes?

If a building is to be demolished, or alterations need to be completed on existing pipework, then that pipework may need ‘decommissioned’. This is affectively removing the existing gas from within the pipe and replacing it with air. This is a critical procedure to ensure that an explosive mixture is not left within the pipework. On larger installations, the pipework is purged with Nitrogen first, then compressed air. This eliminates any potential of an explosive mixture in the pipe as Nitrogen is an Inert gas.

Who Are Some Regular Clients That Comgas Does This Work For?

Regular purging customers for decommissioning purposes are Exoteric, Kensa Business Solutions, CHES, FES, The Glen Turner Distillery, Woodburn Utilities.
