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

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

EPDM Materials good for up to 300

°

F for pressures 15 PSI or less.

PROCO 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 Indus-

trial Process Piping Systems, Power Generating Systems, Marine Services, Pulp & Paper Systems, Water-Waste-

water-Sewage and Pollution Control Systems. Installed next to mechanical equipment or between the anchor

points of a piping system, specify the PROCO Series 240 or 242 to: (1) Absorb Pipe/Movement/Stress, (2) Re-

duce System Noise, (3) Isolate Vibration, (4) Compensate Alignment/Offset, (5) Eliminate Electrolysis, (6) Pro-

tect Against Start-Up/Surge Forces. Our history in the manufacturing 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 PROCO Series 240 and Series 242 are inherently

stronger than the conventional hand-built Spool Type arch. Internal pressure within a

sphere is exerted in all directions, distributing forces evenly over a larger area The spheri-

cal design “flowing-arch” reduces turbulence, sediment buildup, thrust area and the ef-

fects of thrust on the piping system equipment when compared to the “high-arch” design

of hand-built standard products.

Greater Movements Are Available

with the PROCO Series 240 and Series 242 when

compared to the movements of conventional hand-built products. Axial compression, elon-

gation, deflection and angular movements in the system are more readily absorbed by

spherical types. These products are more forgiving and can be compressed or extended

to install in non-standard openings, caused by equipment shifting or settling (Pre-com-

pressing/extending the expansion joints for installation, may result in reduced pressure,

vacuum and movement capabilities of the expansion joints. See Tables 2 and 3.)

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, provided the expansion joints are mated against a flat face flange as

required in the installation instructions.

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 prod-

ucts. Lower spring forces are therefore required, reducing piping/flange/equipment stress-

strain-damage. PROCO Styles 240-C and 240-A are acceptable for use with plastic piping

systems where even lower deflection forces are required.

Specifications Met.

The PROCO Series 240 and Series 242 are designed to meet or ex-

ceed the pressure, movement and dimensional rating of the Spool Type arch as shown in

the Rubber Expansion Joint Division, Fluid Sealing Association “Technical Handbook -

Sixth Edition” Tables IV & V.

Absorbs Vibration-Noise-Shock.

The PROCO 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-borne noises are cushioned and absorbed by the molded lightweight thin-wall struc-

ture. 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 PROCO Spherical 240 and 242 connectors are furnished

complete with plated carbon steel flanges for corrosion protection. Series 240 and 242

Neoprene connectors — 12" and below — are tapped to ANSI 125/150# drilling. All other

connectors come with standard drilled holes to the ANSI 125/150# standards (see Table 7

and Figures 3 & 4). Stainless steel flanges and other drilling standards such as: ANSI 250/

300#, BS-10, DIN NP-10 and DIN NP-16 are also available from stock and are listed on

Table 7. JIS-5K and JIS-10K are also available upon request.

Chemical Service Capability At Minimal Cost.

Expensive, exotic metal expansion joints

for chemical service can be replaced with the PROCO 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 below). Use the PROCO “Chemical/Rubber Guide” to specify an elas-

tomer recommendation compatible for your requirement.

Wide Service Range With Low Cost.

Engineered to operate up to 300 PSIG and 265

°

F,

the PROCO Series 240 and Series 242 can be specified for a wide range of piping require-

ments. Compared to conventional hand-built Spool Type arch, 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 in several elas-

tomers 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!
