EXPANSION JOINTS

Rubber expansion joints compensate for axial, lateral and angular movements resulting from thermal changes in pipeline length. They prevent the transmission of mechanical vibrations from machines, apparatus or pumps to the connected pipeline. They compensate for tension and imprecision in assembly, and are now able to withstand – depending on the application requirement – pressures of up to 40 bar.

Features:

Absorb Axial movements (extension and compression).

  • Axial movement is the change in dimensional length of the bellows from its free length in a direction parallel to its longitudinal axis.

Absorb Lateral movements.

  • Lateral movement is the relative displacement of one end of the bellows to the other end in a direction perpendicular to its longitudinal axis.

Absorb Angular and Torsional Movements.

  • Angular movement is the rotational displacement of the longitudinal axis of the bellows toward a point of rotation. Torsion refers to twisting one end of the bellows with respect to the other end, about the bellows centerline.

Reduce Vibration.

  • Rubber expansion joints isolate or reduce vibration caused by equipment. The transmission of vibration is reduced and they protect equipment from these adverse effects.

Dampen Sound Transmission.

  • Rubber expansion joints tend to dampen transmission of sound because of the steel-rubber interface of joints and mating flanges

SPECIAL EXPANSION JOINTS

DOG BONE

One of the main functions of the Dog Bone Expansion Joint is to absorb the differential thermal expansion between the steam turbine and the condenser while imparting minimal forces and moments on the turbine exhaust flange
