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
- flush-boring process
|
|
Cost-effective
|
|
Installation times are very short compared to the time required to lay and assemble a conventional double-walled pipe - so the FHK solution is not only technically perfect but also highly cost-effective.
