OPTIONS & ACCESSORIES
]

BRAIDED HOSE SEAL (BH)
Flexible stainless steel braided hose with enclosed ceramic insulation is often
specified for expansion joints in areas of high particulate loading. The hose is
secured between the flow liners to prevent particulate from entering the
expansion joint cavity. This accessory along with a cavity pillow works
well in cement plants.
TADPOLE GASKET TAPE (TG)
When using integral flange-type expansion joints in duct systems with
positive pressure operating conditions, Senior Flexonics Pathway
recommends the use of tadpole gasketing between the flexible element
flange and backup bars (as illustrated). This prevents the heads of the
erection bolts from abrading the outside cover of the flexible element.
This option also protects both flat and integrally flanged belts during large
TP
lateral or compression movements.
FD
FLOW DEFLECTOR (FD)
In some expansion joint installations, an angle flow deflector is added to the design to
increase the service life of the joint. A flow deflector is used to prevent moisture and
particulate from sliding down vertical duct walls and being trapped in the expansion
joint cavity by the flow liner.

FRAME STYLES
]
–-–
Senior Flexonics Pathway provides numerous frame designs for various applications. The integrally flanged U-belt
design has a very economical initial capital cost. The flat belt frame design has a lower replacement belt cost and
existing hardware can be reused. The following is a sample of several standard arrangements.
SR2400
Design applications where the ductwork flanges are present and a complete frame
assembly is preferred. This style works well for high temperature applications.
■
Complete drop-in assembly
■
Prefabricated standard frames reduce cost
■
Belting hardware accessible from outside
■
Best choice when adjacent structures or equipment cannot permit liner
SR2400
protrusion beyond attachment flange.
■
Accepts shop welded flow liner
■
Readily accepts eared pillow design
■
Used to fill large breech openings
■
Accommodates large lateral movements
■
Provides proper setback for belt protection
Senior Flexonics Pathway expansion joints are furnished assembled or unassembled.
