Description of CuFlex Pipe System

Vital Energi Flexible CuFlex pipe systems are advantageous for house connections in district heating installations and secondary networks. CuFlex is also used for distribution of both hot and cold domestic water systems.

CuFlex pipes can be operated up to 120°C and the maximum working pressure is 16 bar. CuFlex flexible pipe systems are available both as single and twin pipe solutions.

Vital Energi CuFlex pipes are fitted with a diffusion barrier to prevent diffusion of cell gases. Thus the insulating properties do not age over their entire service life.

Applications for CuFlex Pre-insulated Pipes:

  • Low Temperature Hot Water (LTHW)
  • Medium Temperature Hot Water (MTHW)
  • Domestic Hot and Cold Water

The general advantages of CuFlex Pipe systems are:

  • Reduction in the number of joints needed through the availability of long lengths
  • Reduction in the number of bends/fittings needed as the flexibility allows the piping to follow the best and easiest path
  • Reduction of waste as pipe can be cut to measure
  • No special considerations necessary to take up thermal expansion
  • Reduction of excavation costs as pipes can be laid on top of each other and/or in very narrow trenches
  • No-dig methods (or boring) can be applied
  • Fully compliant with CIBSE CHPA Heat Networks Code of Practice
