PertFlextra – A NEW FLEXIBLE PIPE SYSTEM to improve the efficiency of District Heating
By Peter Jorsal, Product & Academy Manager, Kingspan LOGSTOR
A new flexible pipe system with plastic service pipe is the result of Kingspan LOGSTOR’s participation in the COOL DH development project. This is the pipe system the district heating industry has been waiting for. The main objective of the COOL DH development project was “to support cities in their endeavor to plan and deploy new, efficient district heating and cooling (DHC) systems and extend and refurbish existing ones to higher standards and thus, allowing greater uptake of renewables, recovering of excess heat or cold while improving the overall efficiency of the systems.”
PertFlextra is a result of the COOL DH development project. More than three years ago, together with other companies, we joined an EU development project, COOL DH.
District Heating as a concept has a vital role in the green tran- sition in Europe, a journey towards fossil-free energy electricity, district heating production, and lower CO2 emissions. The green transition has kickstarted a massive need for expand- ing existing and building new district heating pipe systems. In many countries, this results in a lack of contractors to do the job. Therefore, the district heating market is looking for a solution that can be a good alternative to traditional steel pipe systems in relevant dimensions where there is no dependency on steel welders. Or, to be more specific:
The Kingspan LOGSTOR objective for the COOL DH project was to “Design and build a low-temperature district heating grid with non-conventional pipe materials. Test new innovative pipe components introduced by COOL DH”.
High speed of installation
The focus of the development project was the following:
Less dependency on steel welders
Develop a plastic service pipe that should have a more robust performance on temperature and pressure than the present standards on the market, service pipe 25 - 110 mm SDR 7,4
Sustainable solutions
Low heat loss over a lifetime
