Flange Forged Steel Rubber Bellows Expansion Flexible Joint For
Pipe
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.
No gaskets required for installation
Elastomeric expansion joints are supplied with flanges of
vulcanized rubber and fabric integrated with the tube, making the
use of gaskets unnecessary in most of the applications. Check
assembly instructions before installation.
Lightweight
Rubber Expansion joints are relatively light in weight,
contributing to lower installation labour costs.
Reduced Heat Loss
Rubber expansion joints reduce heat loss, giving long
maintenance-free service.
