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.
