PROCO Series 230, Styles 231, 232, & 233 Non-Metallic Expansion Joints are designed
for tough, demanding industrial applications, as found in: Chemical/Petrochemical Plants,
Industrial Process Piping Systems, Marine Services, Power Generation Plants, Pulp/
Paper Plants, Steel Mills, Water/Wastewater and Pollution Control Systems. Installed
next to mechanical equipment or between the anchor points of a piping system, specify
the PROCO Series 230 to: (1) Absorb Pipe Movement/Stress, (2) Reduce System Noise,
(3) Isolate Mechanical Vibration, (4) Compensate Alignment/Offset, (5) Eliminate Elec-
trolysis, (6) Protect Against Start-Up Surge Forces. Our history in the manufacture of
expansion joints dates back to l930. When you need an engineered rubber expansion
joint solution to a piping problem, call PROCO!
Series 230 Replaces Series 220. The new and improved PROCO Series 230 replaces the
PROCO Series 220 rubber expansion joints. (Series 220 products will be available only in
short neutral lengths.) This new hand-built product has been completely re-engineered to
provide improved strength, flexibility, movement and spring rate capabilities. Manufac-
tured utilizing tire industry technology, the Series 230 combines woven nylon fabric and
nylon tire cord into a fabric matrix bonded with elastomer and reinforced with wire to
create a product with greater operating performance. The nomenclature for the new PROCO
Series 230 is as follows:
Single Arch Series 230, Style 231
Double Arch Series 230, Style 232
Triple Arch Series 230, Style 233
Greater Movements With A Lower/Wider Arch Profile. The movements for the PROCO
Series 230 exceed the specification of the Fluid Sealing Association's Rubber Expansion
Joint Division Technical Handbook (Sixth Edition), Table V. Due to a new and improved
lower, wider profile arch, more axial compression and axial extension coupled with lateral
misalignment, angular and torsional movements can be obtained without increasing the
face-to-face requirements. Installation of the Series 230 in a piping system will negate the
need for long and expensive multi-arch products. For greater movements based on re-
engineering and new product construction, specify the PROCO Series 230.
Less Turbulence Or Material Entrapment. The PROCO 230 Series molded integral flange
joins the body at a true 90 ° angle. Our product will install snug against the mating pipe
flange without voids. The flange body of the rubber expansion joint is difficult to form and
many manufacturers radius the edge angles. The resulting void between the mating flange
and the edge angle can create flow turbulence and allow for material entrapment or
bacterial growth. You can avoid these problems by specifying PROCO Series 230 rubber
expansion joints.
Chemical Or Abrasive Service Capability. Expensive metallic designs for chemical ser-
vice can be replaced with the more cost-effective PROCO Series 230. Built with low-cost
chemical resistant elastomers, such as Chlorobutyl, DuPont Dow Elastomer Hypalon ®
rubber, EPDM, Natural, Neoprene and Nitrile, assures an expansion joint compatible with
fluid being pumped or piped (See Table 1). When handling abrasive products such as any
solids or slurries, Natural or Neoprene filled arch products should be specified. Please
refer to PROCO "Chemical to Elastomer Guide" for recommendations on elastomer chemical
compatibility for piping processes.
Exclusive Sealing Bead Means A Quick Seal. PROCO has built an "O-Ring" on each
flange face of the Series 230. Available only from PROCO, the Series 230 seals faster with
less torque at installation. For these exclusive features, specify the PROCO Series 230
rubber expansion joints.
Specifications Met. PROCO has assigned conservative pressure ratings to the Series
230 rubber expansion joints. The ratings, however, meet the requirements of the Fluid
Sealing Association's Rubber Expansion Joint Division Technical Handbook (Sixth Edi-
tion), Series C. The pressure ratings for the Series 230 rubber expansion joints have been
fully tested and are based on a minimum four-to-one safety factor. For pressure protec-
tion with confidence, specify the PROCO Series 230.
Tested Force Pound And Spring Rate Tables. The Series 230 rubber expansion joints
are in accordance with and/or lower than the guidelines for spring rate data as listed in
the Fluid Sealing Association's Rubber Expansion Joint Division Technical Handbook
(Sixth Edition), Table V. Due to a lower, wider arch profile, the PROCO Series 230 will
provide more flexibility than conventional spool-type rubber expansion joints. In addi-
tion, the lower/wider arch profile coupled with a modified radial tire cord construction
will result in lower flange forces. Lower resultant forces mean reduced stress of related
piping system components. PROCO is currently testing each rubber expansion joint
size and will list actual test data as opposed to listing hypothetical data normally asso-
ciated with spring rate tables.
Absorbs Vibration • Noise • Shock. The PROCO Series 230 quiet-operating rubber ex-
pansion joints are a replacement for "sound transmitting" metallic expansion joints. Sound
loses energy traveling axially through an expansion joint. Water hammer, pumping im-
pulses, water-borne noises and other forms of strain-stress-shock are cushioned and
absorbed by the molded elastomer expansion joint, not related to piping. Install the Se-
ries 230 in a system to reduce vibration transmission when the piping section beyond the
expansion joint is anchored or sufficiently rigid. For quiet, stress-free systems, specify
the PROCO Series 230.
Wide Service Range With Low Cost. Engineered to operate up to 200 PSIG or up to
250°F, the PROCO Series 230 can be specified for a wide range of piping system require-
ments. Compared to competitive products, you will invest less money when specifying
the engineered design and industrial quality of the PROCO Series 230.
Large Inventory Means Same-Day Shipment. We maintain the largest inventory of
elastomeric expansion joints in the world. Ever y size cataloged up to 72" is in stock
in a variety of elastomers. We can ship the products you need when you need them!
In fact, when it comes to rubber expansion joints, if PROCO doesn't have them in
stock … nobody does!
