Description
A rubber expansion joint is a flexible pipe fitting designed to absorb movements, vibrations, and noise in a piping system. It comprises a rubber body and metal flanges or inserts, offering high flexibility to compensate for axial, lateral, and angular movements, preventing stress and damage caused by thermal expansion and vibrations. These joints absorb vibrations, reducing noise levels and extending equipment lifespan. They are corrosion-resistant, easy to install, and low maintece, finding applications in industries like HVAC, power plants, and chemical facilities where compensating for thermal movements and vibrations in pipelines is crucial. Various types, such as single sphere and multiple arch designs, cater to specific movement requirements and are chosen based on factors like temperature, pressure, and application needs.
