aquatherm offers a modern PP piping solution for 4th generation district heating and other projects with operating temperatures up to 80 °C.

Self-compensating pipe system

for underground installation

aquatherm insulated PP piping systems are self-compensating during installation. They can be installed without compensation for temperature-related changes in length.
Plastics have a greater linear expansion than steel but a lower modulus of elasticity, so that only low stresses are generated in the polymer medium pipes.

Advantages

• 100% corrosion free system

• No need for steel welders

• Safer work, as the pipes are often connected above ground (not in the trench)

• Less depth required in the trench

• Less complex test procedures

• The speed with which aquatherm PP-R can be laid reduces the installation costs of a heating network

• The flexibility of aquatherm PP-R allows a more direct installation instead of bypassing existing pipelines and other structures

• The weight of aquatherm PP-R is a great advantage of the system

• Less open trench required due to faster installation

• Significantly lower pump performance due to elimination of expansion loops and smooth inner surface compared to steel pipes
