Abstract

A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.

Dependent claims

A length compensator for pipelines comprising:

an elastic compensating element in the form of a tube made from a thermoplastic elastomer (TPE),
two connecting components for connecting pipes to ends of the compensating element tube,
a rigid supporting pipe having a straight walled inner surface concentrically surrounding the entire length of a straight walled outer surface of the compensating element tube, the supporting pipe and compensating element tube being configured so that the compensating element tube slides inside the pipe and expands and contracts exclusively in the axial direction to compensate for changes in length of the pipeline, and
wherein the connecting components have the same internal diameter as the compensating element tube, one of the connecting components having an end fixed to one end of the compensating element tube and the other connecting component being fixed to an opposite end of the compensating element tube.
