What is a Flanged Rubber Joint?
A flanged rubber joint is a flexible connector used in piping systems to accommodate various movements, reduce vibration, and compensate for misalignment. It consists of a flexible rubber body with integral rubber flanges at each end. These flanges are designed to mate with corresponding pipe flanges, creating a tight seal without the need for additional gaskets.
Flanged rubber joints offer several advantages:
Movement Absorption: They can absorb axial (compression/elongation), lateral (side-to-side), and angular (bending) movements in piping systems, which can be caused by thermal expansion/contraction, building settlement, or dynamic machinery operation.
Vibration and Noise Reduction: The rubber material effectively isolates and dampens vibrations and noise transmitted through the pipeline, protecting equipment and improving the working environment.
Misalignment Compensation: They can compensate for minor misalignments in piping runs, simplifying installation and reducing stress on the system.
Corrosion and Abrasion Resistance: Depending on the elastomer used (e.g., EPDM, Neoprene, Buna-N), these joints can offer excellent resistance to various chemicals, abrasion, and erosion.
Easy Installation: Many flanged rubber joints feature "floating flanges," which allow for easy rotation and alignment during installation, making it simpler to line up bolt holes.
No Gaskets Required: The integral rubber flanges eliminate the need for separate gaskets, reducing potential leak points and maintenance.
