• A.C.: Axial Compression, A.E.: Axial Elongation, A.M.: Angular Movement, T.M.: Transverse Movement
  
• Mass indicates only the case with PN16(Mild Steel) flanges.
• Products should be used within the given allowable movements only.
• Tolerances for installation are included in the allowable movements
  (Allowable movements = Tolerances for installation + Operating movements).
• Please note that the information in the above table is for single movement only.
  In case of complex movements, please do adjustment by using the following formula.
  C.A.E. (C.A.C.) = A.A.E.(A.A.C.) {1 (T.M / A.T.M. + A.M. /A.A.M)}
  C.A.E. (C.A.C.): Correct Elongation Movement (Correct Compression Movement)
  A.A.E. (A.A.C.): Allowable Elongation Movement (Allowable Compression Movement)
  A.T.M.: Allowable Transverse Movement
  A.A.M.: Allowable Angular Movement
  Example: In case of 100mm joint, if 5mm transverse movement is needed, then the correct elongation should be: C.A.E = 10 {1 (5/10 + 0/7 )} = 5mm
• There is reaction force from rubber joints due to the load of the internal pressure, so during the installation, please fix the pipe tightly to ensure the joints work efficiently. In case the pipe cannot be fixed tightly, please use the control unit for the joints.
