Brugg FLEXWELL Pre-insulated Flexible Pipe


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

FLEXWELL FHK is bendable, supplied in continuous lengths of coil and can be looped from one point to another. This flexible design results in no buried connections, and no welding and leak tests required along the pipe route. This unique pipe can also be directionally drilled with minimal disruption where trenching is not possible or desired.
