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.
