RUBBER EXPANSION JOINT
Functions:
Engineers can solve anticipated problems of vibration, noise, shock, corrosion, turbulence & abrasion, Stresses, Seismic stresses, Fatigue factor and space by incorporating rubber expansion joints into designed piping systems. ‘APHROFLEX’ Rubber expansion joints shall compensate Axial compression, Axial elongation, Lateral, Torsional and Angular Movements.
