UNAFLEX® "Radi-Flex" Elbow Expansion Joints are
designed to reduce noise and vibration. Their flexibility also prevents
damage to equipment from pipe line expansion and contraction. Spiraled
steel wires are embedded in the walls from flange-to-flange for extra
strength. They are excellent for corrosive or abrasive applications when
steel pipe will not hold up.
Standard construction is of natural rubber tube with polyester
reinforcement and a synthetic cover. Temperature ranges up to 180ºF can
be handled. High temperature construction is a butyl tube with polyester
reinforcement and a butyl cover for maximum operating temperatures of
180 to 250ºF. They are also available in Neoprene, Buna N, Hypalon and
EPDM (Nordel). It is necessary to specify whether the elbow is to be
used for pressure, vacuum, or pressure and vacuum as the construction
differs.
The maximum operating pressures for standard models is: 1 1/2" to 3" 90
psi; 4" to 6" 80 psi: 8" to 10" 70 psi; and 12" to 14" 60 psi.
NOTE: In order to eliminate elongation, it is imperative that the
piping at both ends of the elbow be properly anchored. |
