Central heating expansion joints are a type of axial expansion joint specifically designed to absorb thermal expansion in central heating systems along the axial direction. These components balance the longitudinal elongation and contraction caused by temperature differences in pipelines, contributing to the safe and efficient operation of the system.

Piping systems are divided into separate expansion zones, which are isolated from one another through fixed points. With this engineering approach, the thermal movement occurring in one expansion zone is absorbed in a controlled manner solely by the central heating expansion joint installed in that specific area.

Since central heating systems often involve long pipeline runs, fluctuating temperatures, and continuous operation, proper placement and the selection of the right type of expansion joint are critically important. Otherwise, the system may experience pressure losses, connection deformations, or sealing problems.

Central heating expansion joints minimize these risks, extend the system’s lifespan, and reduce maintenance requirements.
