FlexCom Metal Bellows Designs:
design the best metal bellows for your specific
application requirements, FlexCom carefully tailors a wide range
of expansion joint design elements in order to achieve the best
possible balance of load (heat, pressure
and movement) tolerances, vibration
dampening and long term joint integrity and reliability.
Some of these elements and design features include:
● Joint Type. Different
applications require fundamentally different metallic
expansion joint designs. FlexCom offers a full selection of
quality solutions, including
Gimbal, Universal and Tied Universal metal bellows
● Joint Size. Joint size is
an important element in FlexCom
expansion joint design. While a smaller joint costs less
and may be more appropriate to your application, a larger joint
generally offering greater elasticity, compensating better for
movement while offering a greater degree of vibration
isolation. A custom joint design finds the right balance for
● Steel Grades. FlexCom
bellows designs are available using a wide variety of steel
grades, different metal types offering different balances of
load tolerance, elasticity and cost.
vs. Multi-Ply Steel. Switching from a single ply of
heavy steel to a multi-convoluted design featuring multiple,
thinner steel plys is an effective way to increase joint
elasticity without negatively affecting load or movement
tolerance. FlexCom offers custom steel joints in either
configuration, per customer specifications.
● Flanges. Steel flanges are
used to mount your FlexCom metal bellows to your
application's ductwork. Custom FlexCom
metallic expansion joints
are designed with flanges customized to match your specific bolt
patterns, in either fixed or floating "cage nut" configurations,
for easy installation in any existing application.
● Tie/Control/Limit Rods.
External steel rods can be added to a FlexCom metal bellows
to provide additional stability and to limit joint movement to a
● Flow Liner. A steel flow
liner is used to protect the internal surface of your FlexCom
metal bellows against abrasion and particulate buildup. In
addition, a flow liner - made from any of a variety of steel
grades - helps to provide a laminar flow.
● External Cover. A metal
bellows cover, built from stainless or galvanized steel, is
used to provide protection against dirt build up and other
contaminants and stresses in your FlexCom expansion joint's
