-––[ HOW A BELLOWS WORKS ]–-–
A bellows is a flexible seal. The convoluted portion of an expansion joint is
designed to flex when thermal movements occur in the piping system. The
number of convolutions depends upon the amount of movement the
bellows must accommodate or the force that must be used to accomplish
this deflection.
The convoluted element must be strong enough circumferentially to
withstand the internal pressure of the system, yet responsive enough to flex.
The longitudinal load (pressure thrust) must then be absorbed by some
other type of device. These devices include pipe anchors, tie rods, hinges, or
gimbal structures. Pressure thrust can be calculated by multiplying the
effective area shown in the catalog by the working pressure.
BELLOWS MOVEMENTS
AXIAL
LATERAL
Pressure Thrust
For the purpose of understanding pressure thrust, a single bellows designed for
pure axial motion can be modeled as hydraulic cylinder with a spring inside.
Force on equipment or adjacent piping anchors “F” = (the effective area of the
bellows) x (the working pressure) + (the spring rate of the bellows) x (the
stroke of the bellows).
ANGULAR
The spring represents the axial spring rate of the bellows. The hydraulic piston
represents the effect of the pressure thrust which the expansion joint can exert on the piping anchors or
pressure thrust restraints (hinges, gimbals, tie rods)
which may be part of the expansion joint assembly.
The area of the hydraulic cylinder would be the
effective area of the bellows. For a 20”, 150 psig catalog
standard expansion joint with 20 convolutions, the
spring force for 1” of axial stroke would be (the axial
motion) x (the spring rate of the bellows) or 1 in. x
1521Ibs./in. = 1521 pounds.
Figure 1. Working pressure acting on the effective
area of the bellows.
The pressure thrust force would equal (the working
pressure) x (the bellows effective area) or (150 Ibs./in.2)
x (359 in.2) = 53,850 pounds.
The pressure thrust force is typically much higher than the spring force.
Expansion joints designed for lateral offset or angular motion are more complicated to model accurately.
However, the effect of pressure thrust is the same.
The pages following the “HOW A BELLOWS WORKS” section describe expansion joints which can be applied
to eliminate the effect of pressure thrust on rotating equipment or other stress sensitive devices.
Pressure Stresses
The ability of a bellows to carry pressure is limited by hoop stress or S2 as defined in the standards of the
Expansion Joint Manufacturers Association (EJMA). This is a stress that runs circumferentially around the
bellows due to the pressure difference between the inside and the outside of the bellows.

Page 7
Hoop stress is what holds a bellows together like the hoops
on a barrel. This stress must be held to a code stress level.
The customer should specify the code to be used.
The bellow’s ability to carry pressure is also limited by
bulge stress or EJMA stress S4. This is a stress that runs
longitudinal to the bellows centerline. More specifically, it
is located in the bellows sidewall and it is a measure of the
tendency of the convolutions to become less U-shaped and
more spherical.

Figure 3.
Pressure
Figure 2. Hoop stress or S2 runs in the
circumferential direction.
For bellows that are not annealed after forming, S4 is allowed by
EJMA to exceed the initial yield strength of the bellows material
by a large margin because it is cold worked. If a bellows is
annealed after forming, S4 must be severely limited because the
bellows sidewall material is no longer cold worked.
Accommodating a requirement for annealing will often result in
the addition of reinforcing rings or a much heavier bellows
material and more convolutions. Our standard policy is to
provide bellows in the as-formed condition to take advantage of
the added performance that is imparted to the bellows through
cold work. Senior Flexonics Pathway will accommodate
annealing requirements on request.
Squirm
A bellows that is pressurized internally is similar in
many ways to a column loaded in compression. At
some loading, a long column will buckle. Similarly,
an internally pressurized expansion joint will
eventually buckle or squirm at some internal
pressure loading. It is the responsibility of the
expansion joint manufacturer to design the bellows
to avoid squirm during operating conditions or
pressure testing.
Squirm can lead to catastrophic failure of a bellows.
Our design equations treat squirm conservatively. A
hydrostatic test of the completed expansion joint
verifies stability. If hydrostatic testing is desired, it
should be specified at the time of order placement.
Stable bellows
Squirmed bellows
Figure 4. Bellows squirm is similar to column buckling.
Cycle Life
When a bellows deflects, the motion is absorbed by bending of the sidewalls of each convolution. The
associated stress caused by this motion is the deflection stress or EJMA stress S6. This stress runs longitudinal
to the bellows centerline. The maximum value of S6 is located in the sidewall of each convolution near the
crest or root.

HOW A BELLOW WORKS (CONTINUED)
Expansion joints are designed to operate with a value for
S6 that far exceeds the yield strength of the bellows
material. This means that most expansion joints will take a
permanent set at the rated axial, angular or lateral motion.
Expansion joint bellows are rarely designed to operate in
the elastic stress range. Therefore the bellows will
eventually fatigue after a finite number of movement
cycles. It is important to specify a realistic cycle life as a
design consideration when ordering an expansion joint.
An overly conservative cycle life requirement can result in
a bellows design that is so long and soft that it is subject to
squirm failure.
Convolution shape
before deflecting
Multiple Ply Construction
S6 or deflection
bending stress
The necessary amount of metal to contain pressure can be
achieved with a single ply of bellows material or multiple
plies of material of reduced thickness. A bellows of
multiple ply construction often has a lower spring rate
than a single ply bellows for the same service. Thin
material experiences less strain than a thick material for
the same deflection. That means a multiple ply bellows
may be shorter and it may have a higher cycle life than a
single ply bellows for the same application.

walls bend to shorten the bellows.

-––[HOW TO INTERPRET A
SENIOR FLEXONICS PATHWAY
BELLOWS DESIGN ANALYSIS ]–-–
SM
All custom bellows designs should be documented to prove that the critical stress values are within the limits
of the selected design code. Documentation should prove that the design is safe and mechanically stable, and
that the cycle life is in accordance with the specification requirements. The Senior Flexonics Pathway bellows
design analysis shows all the critical information in a summary format. The following explanation is offered
to help customers interpret the information that is shown on the Pathway bellows design analysis so the
information is more meaningful.
This is the actual temperature used for the bellows design. For
certain applications such as refractory lined expansion joints,
the bellows is often designed for a lower temperature than the
media.
This is the allowable primary stress for the bellows material at
the design temperature.
This is the modulus of elasticity of the bellows material at the
design temperature. The room temperature modulus of
elasticity is used to calculate the deflection stresses (S5 & S6).
The longitudinal weld joint efficiency varies based on the
method of inspection and the specified code.
The design movements create the deflection stresses that
determine cycle life. One complete cycle is based upon
moving the bellows from the installed position to the
maximum specified movement and then back to the installed
position.
Material thickness is stated as the standard sheet gauge
thickness.
Hoop Stress (S2) is a critical membrane stress that runs in the
circumferential direction. The S2 value must be lower than the
allowable stress for the bellows material multiplied by the
bellows longitudinal weld joint efficiency.
The bellows effective area is the area of
the bellows that creates pressure thrust
when acted upon by the operating
pressure. The system anchors and/or the
hardware on the expansion joint must
be designed to withstand pressure thrust
at the operating and test conditions.
Torsional spring rate is offered for those
pipe stress analysts who are inputting
bellows characteristics into a pipe stress
program. Bellows are not generally
designed for torsional movements. But,
the torsional stiffness value can affect the
output of a pipe stress analysis that
includes an expansion joint.
The proposed design has this
calculated cycle life at the specified
conditions.
There are two types of squirm or instability
that can occur for internally pressurized
bellows. One is called column squirm
(similar to buckling of a column) and the
other is called in-plane squirm (localized
plastic deformation). Senior Flexonics
Pathway calculates the maximum stability
pressure based on the lower of the two
values. The design stability pressure is the
predicted squirm pressure divided by a
safety factor of 2.25.
The Senior Flexonics Pathway spring rate
calculations are based on the initial elastic
spring rate criteria from EJMA.
Pressure Bending (S4) is a critical bending stress that is located
in the sidewall of the convolution running in the longitudinal
direction. It is the stress that makes a “U” shaped convolution
balloon out into an omega shape. The value of S3 + S4 must
be limited to 1.5 times the allowable stress for annealed
bellows and 3 times the allowable stress for bellows in the
asformed condition.
Deflection Bending (S6) is the primary bending stress
influencing fatigue life. This stress runs in the longitudinal
direction and is most severe near the convolution crest or root.
Since bellows operate in the plastic range, the value of S6 is
generally well above the allowable code stress value. It is a
theoretical calculation based on elastic theory, and the value is
used to calculate cycle life.
This is the specified cycle life value. If ASME B31.3 or ASME
Sect. VIII are specified, this value should realistically represent
the actual number of cycles the bellows will experience in
service. This is typically in the hundreds of cycles, not
thousands.

-––[ APPLICATIONS]–-–
Single Expansion Joints AS have one bellows. Axial compression and extension, lateral and angular
movement can be accommodated. These expansion joints do not restrain the internal pressure thrust. The
piping designer must provide the system with separate anchoring and guiding to resist the pressure thrust.
Where small thermal movements are involved and proper anchoring and guiding is feasible, a single
expansion joint is the most economical installation.
SINGLE UNRESTRATINED AS
Tied Single AT Expansion Joints also have one bellows, except the overall length is restrained by tie rods
designed to contain pressure thrust. A tied single is usually designed for lateral offset so that the tie rods can
remain fully engaged and loaded with the pressure thrust force. A two tie rod design can accept angular
deflection in a single plane.

Universal AU Expansion Joints consist of two bellows separated by a pipe spool. This configuration
accommodates large lateral movements, in addition to axial compression and extension and angular
deflection. These expansion joints have no restraints to resist pressure thrust and like the singles, the
piping designer must provide separate anchoring to handle pressure thrust.
UNIVERSAL AU
Universal Tied, AUT Expansion Joints contain two
bellows separated by a pipe spool and tie rods designed to
contain the pressure thrust force. These expansion joints
are generally designed to accommodate lateral movement only. A universal expansion joint can be designed
to have a very low lateral spring force to minimize forces on adjacent equipment. A two tie rod design can
also accept angular deflection in a single plane.
The tie rods are usually at or near ambient temperatures and, therefore, do not expand and contract as a
function of the temperature of the media within the pipe. As a result, the thermal expansion of the length of
pipe between the tie rod end plates is forced into the bellows as an axial movement. The bellows design must
accommodate this axial thermal expansion as well as the specified lateral movement.
UNIVERSAL TIED AUT
Sometimes a universal expansion joint has a very heavy center spool that can exert excessive weight on
the bellows elements. To protect the bellows elements from excessive lateral loads, a support system such
as a slotted hinge can be installed across the individual bellows elements to support the dead weight of the
center spool.

APPLICATIONS (CONTINUED)
Hinged Expansion Joints AH have a single bellows with overall length
restrained by hinge hardware designed to accommodate pressure thrust. A
hinged expansion joint allows angular movement in a single plane.
HINGED AH
Universal Hinged AUH Expansion Joints have two bellows separated by a pipe spool with overall length
restrained by hinge hardware designed to contain pressure thrust. A
hinged universal expansion joint accepts large lateral movements in
a single plane with very low spring forces.
UNIVERSAL HINGED AUH
A three-hinge system can accommodate very large movements with very low reaction loads on the adjacent
equipment. This is a very attractive application for large diameter hot piping systems if the movements are in
the same plane.
Gimbal AG Expansion Joints have a single bellows and gimbal hardware
designed to resist pressure thrust. The gimbal expansion joint hardware operates
like the universal joint on a drive shaft to accommodate angular movements in
any plane.
GIMBAL AG
Universal Gimbaled AUG Expansion Joints are similar to the hinged universals except that the two
expansion joints are gimbal type. The advantage of this arrangement is the ability of the expansion joint to
accept large lateral movements and independent angular
movements in any plane.
UNIVERSAL GIMBAL AUG
A system consisting of two gimbals and a hinge can accommodate very large movements with very low reaction
loads on the adjacent equipment. This is a very attractive application for large diameter hot piping systems
even if the movements are complex and not in a single plane.

Pressure Balanced Expansion Joints are devices which produce no pressure thrust forces in the piping
system on the main anchors. In addition to eliminating the pressure thrust, the expansion joint can accept
axial compression, axial extension, lateral and angular movements. The balancing thrust is created by using a
balancing bellows.
Pressure Balanced Elbows are expansion joints which can consist of a single or double bellows in the
flow section, and a balancing bellows of equal area on the back side of the elbow. Tie rods attach the
outboard end of the balancing bellows to the outboard end of the flow bellows. Under pressure the tie rods
are loaded with the pressure thrust force. If the flow bellows compresses in service, the balancing bellows
extends the same amount without exposing the adjacent anchors to pressure thrust forces. However, the
spring forces associated with bellows movements are imposed on the adjacent equipment. A pressure
balanced elbow type expansion joint can accept axial compression, axial extension, lateral movements and
very limited angular motion.
In-Line Pressure Balanced Expansion Joints consist of single or double (universal) bellows to accept the
piping induced axial compression, extension and lateral movements. An oversize bellows with
approximately two times the area of the flow bellows is used to create an annular pressure chamber that
produces a balancing pressure thrust force. Tie rods are used to link the bellows elements and contain the
pressure thrust force. In-Line pressure balanced expansion joints are typically used in straight pipe runs
between intermediate anchors (non pressure thrust resistant) or adjacent to rotating equipment that cannot
operate with large externally applied loads.

b) Over 6” Dia. flow greater than 10 ft/sec (over 150 mm Dia. flow greater than 3.0 M/sec)
HEAVY-DUTY LINERS (PART NUMBER HL)
Heavy-duty liners should be used in the following conditions:
• When high velocity, extremely turbulent or damaging two-phase flow exists upstream of the bellows.
• When extremely high temperatures are present, the liners can create an insulating barrier which would
permit the bellows to operate at lower temperatures ensuring longer life and resisting oxidation. Steam
purging and/or insulation can be added to enhance protection.
• When the media is erosive such as in catalyst carrying services.
• When an expansion joint is located within 10 pipe diameters downstream of an elbow, tee or valve.
When liners are specified, Senior Flexonics Pathway should be provided with the axial, lateral and angular
movement expected. This is required so that the diameter of the liner can be properly determined to avoid
interference with the downstream pipe or flange.
TIE RODS OR LIMIT RODS (PART NUMBER T)
This part number designation adds threaded rods that are designed to contain
pressure thrust. The rods will have nuts or stops on the ends of the assembly to limit
the overall length. When an expansion joint is designed for pure lateral offset the
rods are defined as Tie Rods. If the expansion joint is intended to absorb axial
motion as well as lateral offset, the rods will have outboard stops to limit the expansion joint to the installed
length plus any specified axial extension. This is defined as a Limit Rod. The designation “T” applies to
either purpose. The required movements determine if the rods are Tie Rods or Limit Rods. Limit rods are
generally used to limit expansion joint movement in the event of main anchor failure. During normal
operation Limit Rods do not contain pressure thrust.
COVERS (PART NUMBER C)
Covers should be specified when:
•
•
•
•
Protection from falling objects or protection from traffic is needed.
Protection of personnel is needed.
Insulation will be applied over the expansion joint.
When high flow velocities may exist around the outside of the
expansion joint, such as in the exhaust of a steam turbine.
Senior Flexonics Pathway always recommends a cover. The small cost for the cover is insurance against costly
downtime due to damage. The standard cover is a removable design.

PURGE CONNECTIONS (PART NUMBER P#)
Purge Connections are installed upstream of the bellows and
downstream of the liner attachment to:
• Prevent packing or caking of media borne solids in the
convolutions which would prevent the bellows from freely
flexing.
• Introduce a cooling media such as steam between the outside
of the liner and the inside of the bellows.
The number of purge connections around the circumference can be specified by adding the number after the
letter P in the Accessories portion of the part number, such as P2 or P3, etc.
PLY TESTABLE (PART NUMBER PT)
A ply testable bellows has an extra ply of material that is not required to satisfy basic design conditions. It is
a redundant ply that acts as a protective barrier between the media and the essential bellows material. By
tapping into the cavity between the redundant ply and the essential
bellows material, it is possible to detect a leak that occurs in the
redundant ply. If a leak occurs, the essential bellows material is still
present to hold pressure with full design compliance.
The ply testable bellows allows for a 100% safety factor on design. This is
a requirement for certain hazardous ASME code applications. It is highly
recommended for applications in which the cost of replacement or cost of
down time for a leaking bellows would be extreme. It is also recommended for applications in which a leak
would be very hazardous to personnel.
RED TOP® LEAK INDICATOR
(PART NUMBER RT)
The ply testable connection on the bellows can be fitted with a
pressure gage or another type of pressure sensing device. However,
bellows are very reliable and pressure gages that never change are
not noticed after a while. The Senior Flexonics Pathway patented
“Red Top” leak indicator is a device that extends a large red button
if a leak is detected. The red button is very noticeable from several
meters distance.

STANDARD FLANGE DATA
This abbreviated flange data summary is to aid system designers in selecting the optimum pipe and duct flanges. The
working pressure at temperature ratings were obtained from applicable flange specifications. Where elevated temperature
data was not available, the rated working pressure at ambient was down rated in accordance with ASME code versus
temperature correction factors.

MATERIALS – COMMON METALLURGICAL PROBLEMS
Failure Mode
Cause
Frequently Used Solution
Chloride Stress Corrosion
Cracking
Chlorides acting on highly stressed
austenitic stainless steel bellows
(T304, T321, etc.)
Use a high nickel alloy like alloy 600
or alloy 625.
Carbide Precipitation
Chromium carbides form in
unstabilized stainless steels (T304,
T316) at high temperature (over 700
F) causing loss of corrosion resistance
at the grain boundaries.
Use a stabilized stainless steel (T321
or T347) or a low carbon stainless
steel (T304L) or another high alloy
material that is less affected by
carbide precipitation.
Pitting Corrosion
Galvanic action causes holes to form
in a bellows, usually from acids.
Use a bellows material containing
molybdenum T316, Alloy 825, Alloy
625) or one of the specialty materials
such as zirconium tantalum or
titanium.
Dew Point Corrosion
Liquid acid precipitates out of a sulfur
rich flue gas stream in contact with
the bellows element that operates
just below the dew point for acid
formation.
Insulate the bellows to insure it
operates above dew point in service
or install a “Hot Blanket” to maintain
a constant bellows skin temperature
that is above dew point.

BELLOWS MATERIAL DATA
Senior Flexonics Pathway engineers can form bellows from most ductile
materials that can be welded by the automatic TIG butt welding process
that results in a homogenious ductile weld structure.
Companies specifying and purchasing bellows must give careful
consideration to the selection of bellows material. When in doubt,
consult with basic supplier mill Metallurgist. Senior Flexonics does not
take responsibility for alloy selection.
Use of these material codes as a suffix in the Catalog part number will
designate the bellows material that will be supplied by Senior flexonics
Pathway.
*ASME “ SA” or “ SB” materials are inventoried and are available upon request
All bellows material purchased by Senior Flexonics Pathway is “mill
annealed” in accordance with ASTM or ASME specifications. Senior
Flexonics Pathway does not perform any other heat treating operations
before welding, after welding before forming convolutions or after
forming convolutions unless specified by purchaser. Heat treatment of
bellows after forming convolutions can lower bellows spring rate
“squirm” pressure, and cycle life. Senior Flexonics Pathway does not
recommend heat treatment be performed unless the bellows is operating
at high temperatures where time dependent properties of creep and stress
rupture become significant.

STEP 5 EXAMPLE
A 12” - 150 PSIG expansion joint is
required to accept 1” of axial
compression and .5” of lateral offset.
The 12 convolution 150 PSIG catalog
part has an allowable lateral offset of
.51”. The example would use up .5/.51
or 98% of the available catalog lateral
movement, leaving almost nothing for
the required axial movement. The 16
convolution 150 PSIG catalog part lists
2.71” of available axial compression and
.91” of available lateral offset. The
example expansion joint would use up
1/2.71 or 36% of the catalog axial
movement + .5/.91 or 55% of the
catalog lateral movement or 36% + 55%
= 91% of the total available catalog
movement. The 16-convolution profile
works. Therefore, the number 16 goes
in the part number.

convolutions works for a required cycle life of 5000. (see pages 22-53)

If spring rate is the limiting design
factor, select the convolution count
that results in a total force that is less
than the required amount for lateral
and axial movements. Keep in mind
that pressure thrust must be added to
the axial spring force for a single
expansion joint that has axial
compression even if limit rods are
specified. To calculate the pressure
thrust force, multiply the area of the
bellows times the operating pressure.
The affective area for any design is
located under the pressure class on
each page of design data. For the
above example assuming 16
convolutions, the pressure thrust is
150*153 = 22,950 pounds. The axial
spring force is 1*1861 = 1861 pounds.
The lateral offset force is .5*2766 =
1383 pounds. (see pages 22-53)

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any nonconcurrent movement tabulated.
2. To combine axial, lateral movements, refer to page 20, step 5.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life refer to page 20, step 5 or
contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should always
be specified.
6. If unit is flanged, see page 16 for maximum flange pressure ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any nonconcurrent movement tabulated.
2. To combine axial, lateral movements, refer to page 20, step 5.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life refer to page 20, step 5 or
contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should always
be specified.
6. If unit is flanged, see page 16 for maximum flange pressure ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any nonconcurrent movement tabulated.
2. To combine axial, lateral movements, refer to page 20, step 5.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life refer to page 20, step 5 or
contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should always
be specified.
6. If unit is flanged, see page 16 for maximum flange pressure ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.
MATERIALS OF CONSTRUCTION
BELLOWS: ASTM A240 T304. To specify alternate bellows
material, add to part number. Refer to page 19.

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any nonconcurrent movement tabulated.
2. To combine axial, lateral movements, refer to page 20, step 5.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life refer to page 20, step 5 or
contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should always
be specified.
6. If unit is flanged, see page 16 for maximum flange pressure ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any nonconcurrent movement tabulated.
2. To combine axial, lateral movements, refer to page 20, step 5.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life refer to page 20, step 5 or
contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should always
be specified.
6. If unit is flanged, see page 16 for maximum flange pressure ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.

STEP 5 EXAMPLE
A 12” - 150 PSIG expansion joint is
required to accept 1” of axial compression
and 2.5” of lateral offset. The 150 PSIG
catalog part with 36” of live length has a
catalog rated lateral offset of 3.87” and
catalog rated axial movement of 2.03”.
The example would use up 2.5/3.87 or
65% of the available catalog lateral
movement and 1/2.03 or 49% of the
available catalog axial movement or 65%
+ 49% = 114% of the rated movement.
That is unacceptable. Going to a 48” live
length the calculation becomes 2.5/5.58
or 45% of the catalog lateral movement
and 1/2.03 or 49% of the available catalog
axial movement or 45%+ 49% = 94% of
the rated movement. That works because
the total is less than 100%. Therefore, the
number 48 goes in the part number.

Select the Live Length based on movement capability and/or spring rate. The live
length is the distance from the outboard end of one bellows element to the outboard
end of the second bellows element. The length of end fittings are added to this
dimension to determine the assembly overall length. Selection of live length is an iterative
process. Working with the movement data for the size and pressure class required, compare the
movements required with the movements available for a given live length. An acceptable design
satisfies the following equation.

MODIFY CYCLE LIFE
The catalog movements are based on a cycle life of 2000 using the Expansion Joint Manufacturer
Association’s calculation method. If a higher cycle life is required, the available catalog movements
should be reduced by the following amount before the above calculation is performed.

APPLICATIO
A 84” live length would be required if the required cycle life were 5000. The catalog
movements for a 12” – 150 PSIG universal expansion joint with 84” live length are 2.03”
available axial compression, 10.78” available lateral offset. The calculation for 5000 cycles
using the above example would look like: 1/(.801*2.03) + 2.5/(.801*10.78) = .61 + .29 =
.90 or 90% of the available movement. The 84” live length works for a required cycle life
of 5000. The OAL is 84” + (2*3 3/4”)(end connectors) = 90.5” (see pages 56-57).
If spring rate is the limiting design factor,
select the live length that results in a total
force that is less than the required amount
for lateral and axial movements. Keep in
mind that pressure thrust must be added
to the axial spring force for a universal
expansion joint that has axial compression
even if limit rods are specified. To calculate
the pressure thrust force, multiply the area
of the bellows times the operating
pressure. The affective area for any design
is located under the pressure class on
each page of design data. For the above
example assuming 48” live length, the
pressure thrust is 150*154 = 23100
pounds. The axial spring force is 1*2481 =
2481 pounds. The lateral offset force is
2.5*131 = 328 pounds. It is acceptable to
interpolate the movements and the spring
rates to obtain a live length that falls
between the catalog values. It is not
necessary to specify the number of
convolutions because all catalog universal
expansion joints are based on the use of 6
convolutions in each bellows element.

Choose the type of each end fittings required (W for weld end, F for flange,
A for angle flange, V for van stoned flange, E for Elbow) using the
illustrations at the top of each odd number data pages 56-67. Review the
bill of material information at the top of each even number pages 56-57 to
understand the standard flange rating, weld end thickness, and materials of
construction that will be applied.

Choose the working pressure
required. If the required pressure
is between one of the listed
values, use the higher of the two values
listed in the catalog. If the required pressure
is above the highest value listed, indicate the
required pressure in the part number and
the factory will custom design an expansion
joint for the application.

1. Rated cycle life is 2000 cycles per EJMA 7th edition for any one
movement tabulated.
2. To combine axial, lateral movements, refer to page 54.
3. Maximum axial extension movement is 50% of tabulated axial
value.
4. To obtain greater movements or cycle life, contact the factory.
5. Catalog pressure ratings are based upon a maximum bellows
temperature of 800°F. Actual operating temperature should
always be specified.
6. If unit is flanged, see page 16 for maximum flange pressure
ratings.
7. Maximum test pressure: 1 1/2 x maximum working pressure.
8. Maximum torque values are on page 68.

-––[ MOMENT AND TORSION DATA ]–-–
The information on the following pages is offered for the benefit of those specifiers who are modeling
expansion joints in computer stress programs.
Forces and Moments
When an expansion joint is offset laterally, the offset force can be assumed to act at a node at the center of
the bellows element if the expansion joint is a single bellows type. If the expansion joint is a universal type,
the offset force can be assumed to act at a node at the center of the spool that separates the two bellows
elements. The expansion joint can be considered as a node with stiffness values acting at the node point.

If the expansion joint is being evaluated as an component with offset loads acting at the ends of the
assembly, there is a moment that must be considered to properly evaluate the effect of the expansion joint on
the adjacent piping. The moment is equal to (the offset force) X (the distance from the end of the assembly
to the center of the bellows element) if the expansion joint is a single bellows type. If the expansion joint is
a universal, the moment is equal to (the offset force) X (the distance from the center of the center spool to
the end of the assembly).

Torsion
Pipe stress programs require that expansion joints be modeled with 6 degrees of stiffness. One of these values
is torsional stiffness. The Caesar II pipe stress program by COADE contains a data base that includes all the
spring rate values for Senior Flexonics Pathway standard bellows elements from this catalog, including torsion
spring rate values. When other software programs are used, the torsional spring rates and torsional limits in
the following tables will be helpful.
Torsion can be very damaging to an expansion joint. Torque causes a bellows to want to take a cork screw
shape, significantly reducing its pressure carrying capacity. If torsion is present in any amount, it is very
important to specify the torsion loading in the inquiry so that the effects of torsion can be taken into
account in the product design. If a significant amount of torsion is present, it may be necessary to add
hardware to the expansion joint to isolate the bellows element from excessive torque. Expansion joint design
engineers assume there is no torsion load on an expansion joint unless a torsion value is specified. Contact
the factory for further information about torsion loading.
The torsion spring rates are based on torsional stiffness for single bellows elements with no lateral offset.
Testing indicates that lateral offset drastically reduces torsional stiffness and the pressure carrying capacity of
the bellows.
The torsion data following is applicable to single bellows elements without hinge or gimbal hardware. A
universal expansion joint without hardware to resist torque is made up of two single bellows elements. The
universal expansion joints specified in this catalog use two 6 convolution bellows elements. Therefore, the
torsion criteria for a standard universal expansion joints should be based on a 12-convolution single bellows
element if the assembly is being evaluated in total. If each bellows of the universal is being evaluated, use the
criteria for a 6 convolution bellows.

5 Year Warranty with alloy 625 bellows
The X-Press bellows absorbs a very long stroke that minimizes the number of expansion joints required for a
typical installation. Inherent in the design are internal guide rings, a full thickness cover, self draining
convolutions, and an integral liner that is insensitive to flow direction. The internal guide rings permit the
designer to reduce the number of guides compared with a conventional internally pressurized bellows system.
The full thickness cover is designed to contain the full pressure of the system. If a bellows leak were to occur,
flow is directed along the pipe rather than radially toward personnel. The heavy wall cover is also very easy
to insulate due to its nominal pipe size. The self draining convolutions eliminate the possibility of sediment
and residue collecting in the convolutions and causing corrosive attack.
The X-Press design is inherently safe. In the event of an anchor failure, the bellows compress and actually
increase its strength. The end rings limit the extension of the expansion joint so that an anchor failure is
controlled and contained. The X-Press does not require maintenance, therefore, it can be installed in areas
where accessibility is limited. Lubrication and repacking are eliminated.
Normally located near an anchor, the single X-Press should be placed with the fixed end adjacent to the
anchor. The double X-Press is typically mounted in the middle of a long pipe run to absorb similar
movements from either direction. A support foot is uncluded with the double X-Press and acts as an
intermediate anchor.
PURGE and VENT CONNECTION located in
the top of the casing, allows the venting of
air or gases to assure a fluid-filled line. In
conjunction with a drain connection, the
vent can be used to flush the X-Press casing.
ANCHOR FOOT for single X-Press can be supplied
to withstand full pressure thrust and can be bolted
or welded in place. The double X-Press includes an
intermediate anchor foot.
DRAIN CONNECTION located in the bottom of the
casing for the removal of dirt, scale, sludge,
condensate and residue. This is an ideal location
for a steam trap when used for steam service.

The X-Press II is an inline externally pressurized, pressure balanced expansion joint. The built in pressure
eompensating bellows eliminates all pressure thrust traditionally created from using unrestrained bellows.
The X-Press II is capable of long axial movements while eliminating pressure thrust on the system. Main
anchors are no longer required!
The unique design also incorporates internal guide rings to minimize external guiding requirements, a full
thickness cover that is easy to insulate, self draining convolutions to minimize corrosion and an integral liner
that insensitive to flow direction. The X-Press can be supplied in single or double ended design. Either type
can be supplied with a support that acts as an intermediate anchor.
Pipe Guide Spacing
Senior Flexonics Pathway recommends the first guide for an X-Press or X-Press II should be located within 12
pipe diameters of the expansion joint. The remaining guides should be spaced in accordance with the
formula below.
L = 0.131*(Ep*Ip/(P*A+SR*AX)).5
L = Maximum intermediate guide spacing (Feet)
Ep = pipe modulus of elasticity (lb/In2)
Ip = Pipe moment of inertia (Inches4)
P = Design pressure (lb/In2)
A = Bellows effective area (Inches2)
SR = Bellows spring rate
AX = Axial movement
Ep - 27,400,000 lb/In2 for carbon steel pipe at 300F.

Many Senior Flexonics Pathway customers have direct burried X-Press Expansion Joints in steam and
condensate service. This eliminates the need for maintenance manways which are inconvenient to locate
and expensive to build. Years of dependable maintenance-free buried service have proven that manways are
not always required nor are they cost effective. Consider this money-saving approach when comparing the
total installed cost of slip joints versus X-Press.
Additional information on direct buried X-Press is available upon request.

If the required
design pressure is less
than 150 PSIG, specify
150 PSIG. If the required

than 150 PSIG but less
than 300 PSIG, specify
300 PSIG. If the required
design pressure is greater
than 300 PSIG, indicate
the required design
pressure in the part

ALLOY 625 WARRANTY
Senior Flexonics Pathway will replace in kind any X-Press style
expansion joint made with Alloy 625 bellows that fails due
to workmanship or corrosion within 6 years of the date of
shipment or 5 years from date of first use. Coverage does not
include field removal and replacement costs or charges
required for obtaining access to the part. Coverage does not
apply to failures caused by over pressurization due to water
hammer, excessive test pressure, or process upset conditions.
Return of the failed part is required for warranty replacement.
Specify an alternate
bellows material.
The standard
bellows material is Alloy 625.
If Alloy 625 is acceptable, it is
not necessary to specify a
material. If an alternate
bellows material is preferred,
indicate the bellows material
from the alloy choices listed
on page 19. Keep in mind
that the five-year warranty
only applies to Alloy 625
because Alloy 625 has
superior corrosion properties
when compared to other
bellows materials in steam
and condensate service.

-––[ INSTALLATION INSTRUCTIONS ]–-–
Senior Flexonics Pathway Expansion Joints are fully
inspected at the factory and are packaged to arrive at
the job site in good condition. Please, immediately
upon receipt at the job site, verify that there is no
freight damage; i.e., dents, broken hardware, loose
shipping bars, etc.
Because the bellows expansion joint is required to absorb
thermal and/or mechanical movements, the bellows
element must be constructed of a relatively thin gage
material. This requires special installation precautions.
The following steps should be taken prior to installation
of the expansion joint into the pipeline or duct.
1. The opening into which the expansion joint will
be installed should be examined to verify that the
opening for which the expansion joint wa
designed does not exceed the installation
tolerances designated by the designer and/or
purchaser. If the opening exceeds the tolerance,
notify Senior flexonics pathway at once for a
disposition.
2. The attachment edges of the pipe or duct should
be smooth, clean, and parallel to each other.
3. The area around the expansion joint should be
cleared of any sharp objects or protrusions. If not
removable, they should be noted so they can be
avoided.
4. Expansion joints provided with lifting lugs
should be lifted only by the designated lifting
lugs. SHIPPING BARS (PAINTED YELLOW) ARE
NOT DESIGNED TO BE LIFTING DEVICES.
NEVER USE A CHAIN OR ANY OTHER
HANDLING DEVICES DIRECTLY ON THE
BELLOWS ELEMENT OR BELLOWS COVER. For
expansion joints not provided with lifting lugs
(i.e., less than 500 lbs.), the best lifting method
should be evaluated at the time of installation.
5. The shipping bars are installed on an expansion
joint to maintain shipping length and give the
expansion joint stability during transit and
installation. DO NOT REMOVE THE SHIPPING
BARS UNTIL THE INSTALLATION IS COMPLETE.
Installation:
The following precautions must be taken when
installing an expansion joint:
1. Remove any protective covering from the ends of
expansion joint. Plywood covers may have been
used to protect flanges or weld ends. Check
inside expansion joint for dessicant bags or any
other material.
82
2. When a flow liner is installed in the expansion
joint, orient the expansion joint with FLOW
ARROW POINTING IN DIRECTION OF FLOW.
3. Using lifting lugs, lift joint to desired location
and position into pipeline or ducting.
4. Weld end expansion joints.
(a) PRIOR TO WELDING, COVER THE BELLOWS
ELEMENT WITH A CHLORIDE FREE FIRE
RETARDANT CLOTH. This is to prevent arc
strikes, weld splatter, etc. from damaging the
bellows element.
(b) Using the proper electrode, weld the
expansion joint to adjacent piping.
DO NOT USE BELLOWS TO CORRECT FOR
MISALIGNMENT OF PIPING UNLESS THIS
HAS BEEN CONSIDERED IN THE DESIGN OF
THE EXPANSION JOINT.
5. Flanged end expansion joints.
(a) Orient expansion joint flanges so that the
bolt holes are aligned with the mating flanges.
DO NOT FORCE THE EXPANSION JOINT TO
MATCH THE BOLT HOLES OF THE MATING
FLANGE. This causes torsion on the bellows
and will severely reduce the bellows capability
during operation and may cause premature
failure of the expansion joint. It is good
practice to leave one pipe flange loose until
the expansion joint is installed or to purchase
an expansion joint with a flange that will
rotate.
(b) Install gaskets and bolt to the required torque
recommended by the flange manufacturer.

INSTALLATION INSTRUCTIONS (CONTINUED)
After installation BUT PRIOR TO
HYDRO TEST
1. Inspect entire system to insure that anchors,
guides and pipe supports are installed in strict
accordance with piping system drawings. A pipe
guide spacing chart is provided below to aid in
this check.
2. ANCHORS MUST BE DESIGNED FOR THE TEST
PRESSURE THRUST LOADS.
Expansion joints exert a force equal to the test
pressure times the effective area of the bellows
during hydro test. Pressure thrust at design
pressure may be found on the individual
drawings. Refer to EJMA Safety
Recommendations.
3. If the system media is gaseous, check to
determine if the piping and/or the expansion
joint may require additional temporary supports
due to the weight for water during testing.
4. REMOVE SHIPPING BARS (PAINTED YELLOW)
PRIOR TO HYDROTESTING. Shipping bars are
not designed for hydrostatic pressure thrust loads.
5. Hydrostatically test pipeline and expansion joint.
ONLY CHLORIDE FREE WATER SHOULD BE
USED FOR HYDROTEST. (published reports
indicate chloride attach of stainless steel bellows
as low as 3 PPM). Water should not be left
standing in the bellows.
Pipe Guide Spacing Table
1. Senior flexonics pathway recommends that for
Flexway™ Single Expansion Joints the first guide be
located within four (4) pipe diameters from the
expansion joint and the second guide be located
within a distance of fourteen (14) pipe diameters
from the first guide. The remaining guides are to
be in accordance with the table below.
2. Senior flexonics pathway recommends that for
X-Press Expansion Joints the first guide be located
within twelve (12) pipe diameters from the
expansion joint. The remaining guides are to be
in accordance with the formula below.
Maximum intermediate guide spacing for any pipe
material or thickness may be calculated using the
following formula:
L
=
0.131
E1
PA Ra
Where L = Maximum intermediate guide
NOTES:

General Precautions
1. Cleaning agents, soaps and solvents may contain
chlorides, caustics, or sulfides and can cause stress
corrosion which appears only after a bellows is
put into service.
2. Wire brushes, steel wool and other abrasives
should not be used on the bellows element.
3. Hydrostatic test pressure should not exceed 1 1/2
times the rated working pressure unless the
expansion joint was specifically designed for this
test pressure.
4. Some types of insulation leach chlorides when
wet. Only chloride free insulation materials
should be used for insulating an expansion joint.
