FHK pipe system

Flexible, endless production, double-walled, monitorable and self-compensating pipe system, -170°C to +150°C, PN 25, DN 25-150. Medium pipe: special steel, heat insulation: PUR

Properties:

FLEXWELL district heating cable ® (FHK) is a pipe system that offers a high level of safety thanks to its double-walled design (with metal inner and outer pipes) and its integrated monitoring system.

Monitoring system

Pipes laid underground with heat insulation can be equipped with operational monitoring systems.
Function:

  • to monitor the heat insulation for external moisture
  • to identify leaks due to damage to the outer pipe
  • to identify leaks due to damage to the inner pipe, for conductive media

Stability under difficult conditions

This pipe – which is laid directly in the ground – has proven its merits in practice for more than 40 years in a wide range of very extreme conditions.

  • difficult pipeline conditions
  • pipes below/inside buildings
  • low clearance/coverage heights
  • culverts
  • installation in protective pipes

Cost-effective

Installation times are very short compared to the time required to lay and assemble a conventional double-walled pipe – so the FHKsolution is not only technically perfect but also highly cost-effective.
