An eccentric reducing rubber expansion joint is a flexible connector used to connect pipes of different diameters.
Its main functions include absorbing and eliminating vibration and noise in the piping system, while compensating for pipe displacement caused by temperature changes. The unique design of this expansion joint lies in its eccentric design and reducing structure, allowing it to adapt to pipe connections of different diameters and effectively reducing stress between pipes.
It is particularly suitable for situations requiring compensation for axial, lateral, or angular displacement in a piping system and the absorption of vibration and noise.
Eccentric Design: Adapts to pipes of different diameters, solving the problem of inconsistent pipe diameters.
Reducing Structure: Achieves a smooth transition between large and small pipes. Unlike concentric reducing joints, the eccentric reducing joint's design places the two connection ends on different centerlines, which helps avoid turbulence and pressure loss during fluid flow.
The eccentric reducing rubber expansion joint mainly consists of a rubber sphere composed of an inner rubber layer, nylon cord reinforcement, and an outer rubber layer, and a loose-fitting metal flange.
This structure makes it a highly elastic, airtight, media-resistant, and weather-resistant pipe joint. Its main functions include vibration reduction, noise reduction, and displacement compensation, effectively improving the stability and reliability of pipeline systems.
During installation, excessive stretching or compression of the rubber joint should be avoided to prevent affecting its performance and service life. Ensure the rubber joint is installed in the correct orientation, paying attention to the direction of the eccentric design. For media containing abrasive particles, high-temperature and high-pressure environments, or transmission of highly corrosive media, wear-resistant or corrosion-resistant rubber materials may be required.
