®
paint
• Standard 150 lb ASA Drilling, Ductile Iron Back-up Rings
• Filled or Unfilled Arches

SERIES
Mercer Flexmore Series 450 is the most economical, full-pressure
elastometric expansion joint available. Tough fabric and tirecord
plies are bonded between the tube and cover in a steel mold
and then cured in a thermostatically controlled steam chamber.
The product is uniform in both appearance and performance.
A wide, low profile arch provides exceptional flexibility and
virtually eliminates the need for filled arches in all but the most
severe sludge and slurry applications. External integral flange
reinforcing rings control both radial and arch swell. A variety
of cover and tube elastomers are available, offering superior
chemical, aging and temperature resistance from -30° to +250°F
(Max 250°F for intermittent service) operating temperatures.

CONTROL RODS
Expansion Joints installed in piping
systems that are anchored on both
sides of connectors need no control
rods, providing piping movements
are within the tabulated allowables.
Expansion joints installed in unanchored
piping or connected to isolated equipment
must have control rods; those control rods must be properly
set so that allowable movements are not exceeded.
The number of control rods is determined by the maximum
working pressure of the pipeline, not the maximum pressure
rating of the joint. Use the convenient chart to the right to
specify. Control rods are designed for a 3:1 safety factor as is;
please use accordingly. For example, if a 24" 452 joint is
installed in a pipeline with a maximum pressure of 120 psig,
3 control rods are required. If the maximum pressure of the
pipeline is 220 psig, 5 control rods are required.

SERIES 450 CONTROL ROD CALCULATIONS
CAUTION
1. Do not install any of the products in this bulletin at
pressures or temperatures higher than the published
ratings.
2. 450 Butyl, EPDM & Viton
®
connectors are recommended
for intermittent (10 minute maximum exposure per hour)
250°F. service or continuous service at a maximum of
225°F. Use Mercer series 500, 600, HT500 or HT600 as
described in bulletin 500-MR7 (pages 9
•
90 - 9
•
97) for
continuous temperatures of 230°F and higher.
3. S eries 450 must be installed against standard
1
/16" raised
faced or flat faced flanges. Do not install them against
recessed flanges such as Victaulic without calling the
factory for proper steel filler flanges. If our rubber flanges
do not have full bearing, the expansion joint will be
damaged and leak or fail.
4. Initial misalignment should be kept to a minimum of
1
/8".
5. P ipe system flanges must be smooth and flat. Screw
in brass inserts such as those used in check valves can
damage the rubber faces if they project above the cast
flange face.
6. Water type check valves must exactly center on the rubber
flanges. Valve O.D. and I.D. should be checked for
conformance with raised face dimensions
7. C heck Chemical Resistance Guide CRG-MR1 (pages 9
•
