Union Double Sphere Rubber Expansion Joint With Filet Fittings
A rubber expansion joint, also known as a flexible connector or compensator, is a crucial component used in piping systems to absorb movement, vibrations, and thermal expansion. These joints are made from rubber or elastomeric materials that provide flexibility and absorb movement, preventing damage to pipes and equipment while ensuring a smoother and quieter operation. Rubber expansion joints also help mitigate the stresses caused by thermal expansion and contraction, which can lead to leaks, cracks, or premature wear and tear.
By absorbing these movements, they contribute to extending the service life of the entire system and maintaining its efficiency.
The Union Fittings with threaded NPT, BSPP,BSPT to connect pipes or nipples to extended the pipeline.

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.
