Developed for the low-temperature range
|
|
CALPEX® is a flexible, self-compensating, continuous and heat-insulated pipe system with a medium pipe made of cross-linked polyethylene.
|
|
No underground connections
|
|
CALPEX® district heating pipes can be supplied in rings of up to 807 m in one piece, depending on the dimensions. This largely eliminates underground connection points.
|
|
Narrow pipe trenches
|
|
CALPEX® district heating pipes only need 60% of the line width required for plastic casing pipes in the past.
|
|
Tight bending radii
|
|
CALPEX® district heating pipe is so flexible that it can easily be adapted to virtually any pipeline conditions. Pipes can pass below or above existing supply lines.
|
|
No expansion zones
|
|
The composite system prevents thermal expansion of the medium pipe. No compensating measures (expansion zones) are required underground.
|
|
Excellent heat insulation values
|
|
The insulation consists of pentane-blown polyurethane foam (PUR). The excellent lambda value of 0.0255 W/mK achieves exceptional insulation values with a small volume.
|
|
Longitudinally watertight
|
|
In the CALPEX® system, the inner pipe forms a composite together with the insulating foam. In case of pipe damage due to external influences, this means that no cavities are created where water could collect and flow toward the building.

Area of application:
|
|
Heat supply pipes, drinking water transportation, drainage/waste water systems, cooling plants, swimming bath technology and agricultural applications are just a few examples from our extensive list of references.
