POLYFLURON - Expansion Joints / Bellows
POLYFLURON bellows have a unique combination of outstanding properties and are suitable for very diverse applications. Because of their near-universal corrosion resistance, they are used particularly as components in chemical plants.
POLYFLURON bellows are installed in steel and PTFE-lined steel pipelines, and especially, thanks to their large adjustment range, in plastic and FRP pipelines. Because of their flexibility and low spring rates, they are also used for sensitive plant components with enameled finishes, graphite process equipment, and graphite heat exchangers. Therefore they compensate thermal expansion of the pipeline and thus prevent stresses, so offering a compact alternative to material-intensive horseshoe bends.
POLYFLURON bellows are also used to absorb oscillations and vibrations, for example those generated by pumps. Here the quite special properties of POLYFLURON are exploited, i.e. its low tendency to material fatigue and complete absence of brittle fracture as compared with other plastics and elastomers or certain metals.
Characteristics of POLYFLURON bellows
POLYFLURON bellows produced by SGL Group are characterized by exceptional safety and long service life. Their operational reliability, in particular, is the result of our special manufacturing process, careful material selection, and targeted optimization through extensive practical trials and FEM simulations. Based on this, we are able to supply POLYFLURON bellows that perform impressively, even under extreme operating conditions.
