206 EZ-FLO Expansion Joints
EZ-FLO
expansion joints contain a single wide flowing
arch, eliminating the need for filled arches on
slurry services. They are successfully used in
all major industries, including pulp and paper,
steel, waste and water, HVAC, power generation,
chemical, petrochemical and marine.

GUARDIAN®
306 EZ-FLO Spool Type Expansion Joints
Featuring
a flowing arch design, these expansion joints have a
mechanically-bonded FEP lining that resists delamination.
They are designed for the chemical processing and pulp
& paper industries, where their ability to resist corrosive
attack at normal or elevated temperatures and pressures
is unequaled.

204, 204HP Spool Type Expansion Joints
Used
to connect concentric pipe flanges in concentric or
eccentric tapers and in connecting piping of unequal
diameters, these expansion joints can be constructed
as single or multiple arch types. Custom designs are
available for full movement capabilities after installation,
ideal chemical compatibilities and easy installation.

GUARDIAN®
200 Expansion Joints
These
expansion joints utilize a chemically resistant FEP
liner mechanically bonded to an abrupt arch. Chlorobutyl
cover is used, and the expansion joint is coated with
a blue protectant for resistance to environmental effects.
(Alternate cover materials available.)

Flow Liners
Metal
flow liners are utilized in conjunction with elastomeric
expansion joints to provide protection from abrasive
materials or solids. Flanged at one end, installed at
the head of the flow, metal liners are tapered to a
5° angle, allowing the expansion joint to laterally
deflect.
