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.
