Rubber
flexible connectors integrate the functions of expansion
joints, flexible connectors and vibration isolators into
one.
As expansion joints, they compensate for pipe thermal
movement, eliminating the need for expansion loops which
require additional material and space.
As flexible connectors, the flexibility of the EPDM carcass
makes them ideal flexible connectors for handling minor
misalignment and offset problems.
As flexible connectors, they protect piping system against
harmful "start-up" and surge forces.
Rubber flexible connectors serve three primary functions in
piping systems, to accept all directional movements,
minimizing pipe stresses and compensate thermal expansion and
contraction.
Rubber flexible connectors are used on both hot and chilled
water circulation lines, suction and discharge sides of
chiller, pumps, cooling towers, etc.
Rubber Expansion Joint has five types: single sphere rubber
expansion joint, double sphere rubber expansion joint,
threaded rubber expansion joint, reduced rubber expansion
joint and rubber bending joint.
4)Generally speaking, there are two kinds of connections:
flange and threaded. It is widely used in water
supply and drainage, recycled water, air conditioning and
heating, fire control, ship, water pump, and compressor, Etc.
They are low cost vibration and deflection absorption in
fluid conveyance pipes. The bellow consists of two
symmetrical connecting end, either threaded unions for small
nominal bores or flanged ends for large nominal bore
pipelines. They are ideal for compensating thermal expansion
and contraction in piping system as an unbeatable cost
effective alternative to expansion loops which require large
amounts of materials and space.
