Project F206:
Trenchless installation methods for district-heating piping systems

Open-trench installation of district-heating piping

Open-trench installation of district-heating piping

Ever greater importance is being attached to the expansion of district-heating networks as energy development progresses. Costs can be saved and resources conserved by installing new piping systems using trenchless technologies.

However, the trenchless installation of district-heating systems frequently encounters scepticism due to a lack of basic knowledge about its use. A research consortium consisting of AGFW, IKT and seven other partners, now intends to identify and eliminate existing technical and non-technical factors limiting trenchless district-heating piping installation.

IKT is performing tests on wear-protection for the plastic jacket of district-heating pipes, and is also participating in market research into products and procedures for trenchless installation of district-heating piping systems.
