Embodiment Construction

[0039] figure 1 The figures illustrated in the figure show the length compensator 1 according to the invention in a longitudinal section in a possible embodiment. The length compensator 1 is used to adapt or compensate changes in the length of the pipe, for example caused by temperature changes. The length compensator 1 has two connecting parts 2 which are fastened between mutually opposite free ends of the pipes. Two mutually opposite end faces of the connecting part 2 in the support tube 4 are connected to one another by means of the compensating element 3 at the compensating element end 8 , wherein alternative connection options are also conceivable. The connection is preferably inseparable and is produced, for example, by a material fit such as welding or by means of an injection molding method, which ensures that the connection is tight.

[0040] For example, the compensating element end 8 is overmoulded and the connection part 2 is formed by means of a two-part injecti...

Abstract

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.

Description

technical field [0001] The invention relates to a length compensator for a pipe, preferably a plastic pipe, and a compensating element thereof, said length compensator comprising: two connecting parts, preferably made of plastic; a compensating element made of elastic material, Preferably made of thermoplastic elastomer (TPE); and a support tube, wherein the compensating element is arranged between two connecting parts and the compensating element ends are connected to the connecting parts. Background technique [0002] Length compensators are used to adapt or compensate for length changes of installed pipelines, which changes are caused, for example, by temperature changes or external influences such as forces caused by earthquakes, pump strokes, etc. The length of the pipe varies depending on the temperature as a result of the external temperature or the medium temperature of the medium conveyed in the pipe. This change in length needs to be accommodated, whether the chan...
