Malleable Steel Rubber Bellow Expansion Joint


Products:Rubber Expansion Joint

A Rubber Expansion Joint is flexible connector fabricated of natural or synthetic elastomers,fluoroplastics and fabrics and, if necessary, metallic reinforcements used to absorb movements in a piping system while containing pressure and a medium running through it.


Advantages:

Reduced fatigue factor
Given the inherent characteristics of natural and synthetic elastomers, they are not subject to fatigue breakdown or embrittlement and prevent any electrolytic action because of the steel-rubber interface of joints and mating flanges.


Extraordinary resistance to abrasion and corrosion
A wide variety of natural, synthetic and special purpose elastomers and fabrics are available to the industry. Materials are treated and combined to meet a wide range of practical pressure/temperature operating conditions, corrosive attack, abrasion and erosion.


Minimal face-to-face dimensions while absorbing large movements
With a minimal face to face length the Rubber Expansion Joints provide superior movement capability in axial compression, axial extension,and lateral deflection, as well as in the angular and torsional direction.


Low Spring Rates due to inherent flexibility of rubber
The inherent flexibility of rubber expansion joints permits almost unlimited flexing to recover from imposed movements, requiring relatively less force to move, thus preventing damage to motive equipment.
