molded expansion joints

PROCOTM Series 240 and Series 242 Non-Metallic Expansion Joints are designed for tough demanding
industrial applications, as found in: Air Conditioning-Heating and Ventilating Systems, Chemical-Petrochemical
and Industrial Process Piping Systems, Power Generating Systems, Marine Services, Pulp & Paper Sys­tems, Water-Wastewater-Sewage and Pollution Control Systems. Installed next to mechanical equipment
or between the anchor points of a piping system, specify the PROCOTM 240 or 242 to: (1) Absorb Pipe/
Movement/Stress, (2) Reduce System Noise, (3) Isolate Vibration, (4) Compensate Alignment/Offset, (5)
Eliminate Electrolysis, (6) Protect Against Start-UP/Surge Forces. Our history in the manufacture of expan­sion joint products dates back to 1930. When you need an engineered rubber solution to a piping system
problem, call PROCO.

Spherical Shapes-Stronger-More Efficient. Featuring an engineered molded style single

or twin sphere designed bellows, the PROCOTM Series 240 and Series 242 are inher­ently stronger than the conventional hand-built “spool Arch” types. Internal pressure
within a sphere is exerted in all directions, distributing forces evenly over a larger area
The spherical design “flowing-arch” reduces turbulence, sediment build-up, thrust area
and the effects of thrust on the piping system equipment when compared to the “high­arch” design of Hand Fabricated-Old Standard products.

Greater Movements Are Available with the PROCOTM Series 240 and Series 242 when
compared to the movements of conventional hand-built products. Axial compression,
elongation, deflection and angular movements in the system are more readily absorbed
by spherical types. These products are more forgiving and thus easier to install in
non-standard openings, caused by equipment shifting or settling. By precompressing
or pre-extending the bellows to the required length, there will still be enough movement
capabilities for operation. (See Tables 2 and 6.)

Easy Installation With Alignable Metallic Flanges. The floating metallic flanges freely
rotate on the bellows, compensating for mating flange misalignment, thus speeding
up installation time (see figures 1, 2, 3 & 4). Gaskets are also not required with the
Series 240 or Series 242. Tapped Holes on flanges are standard for the series 240
and Series 242 designs (up to 12” I.D.) which eliminate the added cost of nuts for
bolting requirements.

Less System Strain With Thin Wall Design. Manufactured by high pressure molding of
elastomer and high-tensile fabric reinforcement, the Series 240 and Series 242 have a
thinner wall section and lighter weight when compared to conventional hand-built prod­ucts. Lower spring forces are therefore required, reducing piping/flange/equipment
stress-strain-damage. PROCOTM Styles 240 A and C or Styles 242 A and C are accept­able for use with plastic piping systems where even lower deflection forces are required.

Specifications Met. The PROCOTM Series 240 and Series 242 are designed to meet or
exceed the pressure, movement and dimensional rating of the “Spool” Arch Types as
shown in the Rubber Expansion Joint Division, Fluid Sealing Association “Technical
Handbook - Sixth Edition” Table V.

NOTES:

2. Expansion joint “cover” (outside) can be Hypalon painted on special order.

3. Products with Teflon “tube” (inside) are not recommended for vacuum service.

4. All elastomers include nylon reinforcing, except EE-9 which is steel cord.

5. All materials meet or exceed the Rubber Expansion Joint Division, Fluid Sealing Association requirements for Standard

Class I and II. EE-9 also meets Special Class II. For more information see The FSA Technical Handbook, Table 1.

6. Materials NN, NP and NH meet all requirements of U.S.C.G.

7. Materials good for up to 300°F for pressures is PSI or less.

Absorbs Vibration-Noise-Shock. The PROCOTM quiet operating Series 240 and Series

242 are a replacement for “sound transmitting” metallic expansion joints. Sound loses
energy traveling axially through the elastomer bellows. Water hammer pumping
impulses and water-born noises are cushioned and absorbed by the molded lightweight
thin-wall structure. Install the Series 240 or Series 242 in a system to enable isolated
equipment to move freely on its vibration mountings; or to reduce vibration transmis­sion when the piping section beyond the expansion joint is anchored or sufficiently
rigid.

Flange Materials/Drilling. All PROCOTM Spherical 240 and 242 connectors are furnished
complete with plated carbon steel flanges for corrosion protection and are tapped (up
to 12” I.D.) to ANSI 150# standards (see Table 7 and Figures 3 & 4). Stainless steel
flanges are also available on special order. Other drilling standards such as: ANSI 250/
300#, British Standard 10, DIN and JIS are also available from stock and are listed in
Table 7.

Chemical Service Capability At Minimal Cost. Expensive, exotic metal expansion joints
for chemical service can be replaced with the PROCOTM Series 240 or Series 242.
Molded with low cost chemical resistant elastomers such as Neoprene, Nitrile, Hypalon,
EPDM and Chlorobutyl; insures an expansion joint is compatible with the fluid being
pumped or piped. (See Table 1). Use the PROCOTM “Chemical/Rubber Guide” to specify
an elastomer recommendation compatible for your requirement.

Wide Service Range With Low Cost. Engineered to operate up to 300 PSIG and 265°F,
the PROCOTM Series 240 and Series 242 can be specified for a wide range of piping
requirements. Compared to conventional hand-built “Spool Arch” types, you will invest
less money when specifying the mass–produced, consistent high quality, molded single
or twin sphere expansion joints.

Large Inventories Mean Same-Day Shipment. PROCO maintains the largest inventory
of spherical expansion joints in the Americas. Every size listed is in stock on several
elastomers and comes with a choice of drilling patterns. Shipment is based on cus­tomer need. PROCO can ship same day as order placement. In fact, when it comes to
rubber expansion joints, if PROCO doesn’t have your requirement...nobody does!

Notes:

1. To determine End-Thrust: Multiply Thrust Factor by Operating Pressure of System. This is End Thrust in P.S.I.G.

2. Pressure rating is based on 170°F operating temperature. The pressure rating is reduced slightly at higher
temperatures.

3. Pressure shown are recommended “operating pressure”. Test pressure is 1.5 times “operating pressure”.
Burst pressure is approximately 4 times “operating pressure”.

4. Vacuum rating is based on neutral installed length, without external load. Products should not be installed
“extended” on vacuum applications.

5. All expansion joints are furnished complete with flanges. Control units are recommended on applications
where movements could exceed rated capabilities.

6. All dimensions are in inches. All weights are in pounds.

Control Rod/Unit Applications. Control unit assemblies are designed to absorb static
pressure thrust developed at the expansion joint. When used in this manner, control
unit assemblies are an additional safety factor, minimizing possible failure of the ex­pansion joint or damage to equipment. (See Table 4).

1. Anchored Systems: Control unit assemblies are not required in piping
systems that are anchored on both sides of the expansion joint, provided
piping movements are within the rated movements as shown in
Tables 2 & 6.

2. Unanchored Systems: Control unit assemblies are always recommended
in unanchored systems. Additionally, control unit assemblies must be
used when maximum pressure exceeds the limit shown in Table 3, or the
movement exceeds the rated movements as shown in Tables 2 & 6.

3. Spring-Mounted Equipment: Control unit assemblies are always recom­mended for spring-mounted equipment. Control units must be used when
the maximum pressure is higher than the ratings shown in Table 3, or the
movement as shown in Tables 2 & 6. Additionally, when control units are
not used, the expansion joint must be installed “extended” in accordance
with PROCOTM installation instructions.

Special Applications. Certain Style 240 (Single Sphere) and 242 (Twin Sphere) expansion
joints are available in High-Pressure Designs. For specific pressures, see Table 5. Style
designations are listed as 240-HW (sizes stocked in Table 2) and 242-HA, 242-HB &
242-HC (sizes stocked in Table 6.) The High-Pressure Design is recommended when
the connector is to be installed into ANSI 250/300# piping systems.
