※Assembly with ANSI150 flange.

・A.C.: Axial Compression, A.E.: Axial Elongation, A.M.: Angular Movement, T.M.: Transverse Movement

TWINFLEX:Twin-Sphere Rubber Joint with Floating Flanges Excellent performance for vibration absorption, displacement absorption and high-pressure resistance.

・Mass indicates only the case with JIS 10K (Ductile Iron) flanges. However,mass for 350&400mm is with JIS 10K(Mild Steel)flange.
・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 10mm transverse movement is needed,
then the correct elongation should be: C.A.E = 15 × {1- (10/25+0/20)} = 9mm
・There is reaction force from rubber joints due to the load of the internal pressure, so during the installation, please use the metal fittings to 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.
