"RADI-FLEX"   ELBOW EXPANSION JOINTS 

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.
NOTES:
  1. Flange size dimension confronts ANSI-Class 125# Cast Iron.
  2. Split rings are 3/8" Galvanized Steel Plate
  3. Center-to-face dimensions are subject to ± 1/4" tolerance.
