Tracpipe Gas Pipe

TracPipe ® - is a flexible gas pipe made from corrugated stainless steel which is wrapped within a protective polyethylene jacket.
It is semi rigid and can be used for natural gas, propane gas or butane gas. It is manufactured by Omegaflex to British Standard 7838 and can replace most conventional installations that would use conventional copper gas pipe in the UK.

What type of applications is flexible gas pipe made for?

Flexible gas pipes are appropriate for new buildings, residential or domestic installations, and commercial premises. The corrugated construction makes it flexible, allowing it to be formed around corners or obstructions. And, because of its flexibility, it needs less joints which in turn reduces the overall installation time. Corrugated gas pipe requires no joints in long runs (master reels are available up to 1950 metres) – so there is no threading, welding or soldering needed. As a result, this eliminates the number of potential gas pipe leaks.

Tracpipe gas pipes are often installed for domestic systems in houses, flats and apartments. And they are also used in schools, hospitals, commercial, and industrial buildings.

It is available in seven nominal bore sizes: DN 12, 15, 22, 28, 32, 40, and 50, and it can be easily jointed and terminated with male BSP fittings.

To correctly size for a job, it is best to determine the ‘maximum design pressure loss’ between the point of supply and the appliance connection points.
Gas pipe installations can be in awkward enclosed spaces or voids where a traditional copper gas pipe may be difficult to install. TracPipe is a less troublesome installation. For projects where copper pipe may need to run along the outside of a building, TracPipe can be fed through walls, under floors and in trenches both inside and outside buildings, and in both domestic and commercial projects, subject to the building regulation requirements.

Kits are available at varying lengths and used when replacing undersized or damaged gas lines in domestic housing.


When used between the meter and gas appliance, the corrugated tubular construction - together with Autoflare Fittings and Autoflare Straight Couplings make most installations easy, fast and safe.


Tracpipe, an excellent alternative to any copper or steel rigid gas pipework, is ideal for UK installers, as it is easy to work with and can save money in material and installation time.


Materials used in flexible gas pipe


Manufactured using flexible Corrugated Stainless-Steel Tube (CSST).


On the outside of the steel tube the yellow polyethylene cover has elements that meet British Standard BS 7838 and BS EN 15266. The cover is proven to prevent flame spread and contains smoke density inhibitors


Tracpipe is designed to resist ignition by different heat sources, prevent smouldering, and minimise heat released after ignition.


BS 7838 is a performance standard that requires CSST to pass mechanical tests, many of which are not included in BS EN 15266. Among these mechanical tests are resistance to corrosion from moisture.
