Arundel Gate Heating Network Renewal

As Principal Contractor, CPC Civils would undertake the installation and renewal of 80m of District Heating pipework from Norfolk Street to Flat Street, Sheffield.

About the Arundel Gate Installation and Renewal Project

The works are essential in maintaining the 44km long Sheffield District Energy Network.  The network has been in operation since 1988.

The integrity of heat distribution pipes, distributing pressurised hot water at 110°C, are key to ensuring the district heating scheme delivers low carbon energy to the city’s communities and businesses.

The pipeline runs beneath Arundel Gate through a tunnel of approximately 40m in length. Consequently, replacement of the pipework would be extremely time consuming and expensive.


Installation and Renewal Project – Installation of Carboseal®

The solution would be to reline the pipework with a Carbon Fiber liner, CarboSeal®.

This is the first installation of this new product for District Heating pipelines, in the UK.

CPC Civils and Colus would attend training in Sweden. There we would to learn how to install the liner. We would then go on to install the product successfully on the District Heating Network in Sheffield.

Carbon lining, which has a minimal impact on system operation, now provides long term security and longevity of the pipe system.

The material has exactly the same expansion, contraction, strength and durability properties as a steel pipe.

The inherent strength of carbon lining makes it self-supporting.

Its design enables it to completely take over the workload of the host pipe while supporting the weight of the system water, alongside maintaining the integrity of the system.

Installation and Renewal Project – Recognising the Benefits

For this installation and renewal project, there are many benefits to lining as listed below:

  • Minimal Excavation required to install the liner. A launch and reception pit are all that is required.
  • No excessive welding or weak spots within the network.
  • No disruption to roads with closures or complex traffic management requirements.
  • Design life is in excess of Steel Pipes (approximately 35 years).
  • Cost savings based on alternative methods.
  • Fast install process meaning disruption to the network is greatly reduced.
  • Reduction in heavy civil engineering can have up to an 80% reduction in CO2 emissions during the construction process.

Andreas Martsman, Managing Director of Carboseal said:

“We are grateful for Veolia UK choosing to be first in the UK to install CarboSeal®.

“Synergi did a great job on the design work and it was a pleasure to train and work with CPC Civils and Colus to realise this install.

“Now we are well set up for helping the UK refurbishing their District Heating Networks in a fast, simple and sustainable way.”

CPC Civils are the only contractor in the UK approved to install the Carboseal® product.

They praised the tidiness, the setup, the workforce attitude and the standard of workmanship completed at the site ”

“I could sit and write multiple examples where CPC and your team have, in my opinion, gone above and beyond what would normally be expected. I would however just like to say that this ongoing attitude, and excellent working relationship, has not only aided Centro in 2 current Metro extensions it has also given me huge confidence in the planning of 5 further Metro extensions. It’s also made my job very enjoyable”
