2 SIS 230/2 spool type wide arch rubber expansion joints POCO Series 230, Styles 231, 2, & 233 on-metallic xpansion 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 POCO Series 230 to: (1) Absorb Pipe Movement/Stress, (2) educe System oise, (3) Isolate Mechanical Vibration, () Compensate Alignment/Offset, (5) liminate lectrolysis, (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 POCO! Series 230 eplaces Series 2. he new and improved POCO Series 230 replaces the POCO Series 2 rubber expansion joints. (Series 2 products will be available only in short neutral lengths.) his new hand-built product has been completely re-engineered to provide improved strength, flexibility, movement and spring rate capabilities. Manufactured 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. he nomenclature for the new POCO Series 230 is as follows: Single Arch Series 230, Style 231 Double Arch Series 230, Style 2 riple Arch Series 230, Style 233 Greater Movements With A Lower/Wider Arch Profile. he movements for the POCO Series 230 exceed the specification of the Fluid Sealing Association's ubber xpansion Joint Division echnical Handbook (Sixth dition), able 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 reengineering and new product construction, specify the POCO Series 230. Less urbulence Or Material ntrapment. he POCO 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. he flange body of the rubber expansion joint is difficult to form and many manufacturers radius the edge angles. he 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 POCO Series 230 rubber expansion joints. Chemical Or Abrasive Service Capability. xpensive metallic designs for chemical service can be replaced with the more cost-effective POCO Series 230. Built with low-cost chemical resistant elastomers, such as Chlorobutyl, DuPont Dow lastomer Hypalon rubber, PDM, atural, eoprene and itrile, assures an expansion joint compatible with fluid being pumped or piped (See able 1). When handling abrasive products such as any solids or slurries, atural or eoprene filled arch products should be specified. Please refer to POCO "Chemical to lastomer Guide" for recommendations on elastomer chemical compatibility for piping processes. able 1: Available Styles Materials emperatures POCO Chemical o lastomer Guide For Specific lastomer ecommendations, See: POCO Style umbers Filled Arch (Single) 6 FA231/BB FA231/ FA231/H FA231/ 5 FA231/P FA231/ otes: Cover 2 Open Arch (Single) 6 lastomer 231/BB 231/ 231/H 231/ 5 231/P 231/ Butyl PDM eoprene eoprene eoprene eoprene ube lastomer Butyl PDM Hypalon 1 eoprene itrile atural Maximum Operating emp.

Available only from POCO, the Series 230 seals faster with less torque at installation. For these exclusive features, specify the POCO Series 230 rubber expansion joints. Specifications Met. POCO has assigned conservative pressure ratings to the Series 230 rubber expansion joints. he ratings, however, meet the requirements of the Fluid Sealing Association's ubber xpansion Joint Division echnical Handbook (Sixth dition), Series C. he 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 protection with confidence, specify the POCO Series 230. ested Force Pound And Spring ate ables. he 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 ubber xpansion Joint Division echnical Handbook (Sixth dition), able V. Due to a lower, wider arch profile, the POCO Series 230 will provide more flexibility than conventional spool-type rubber expansion joints. In addition, 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. POCO is currently testing each rubber expansion joint size and will list actual test data as opposed to listing hypothetical data normally associated with spring rate tables. Absorbs Vibration oise Shock. he POCO Series 230 quiet-operating rubber expansion joints are a replacement for "sound transmitting" metallic expansion joints. Sound loses energy traveling axially through an expansion joint. Water hammer, pumping impulses, 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 Series 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 POCO Series 230. Wide Service ange With Low Cost. ngineered to operate up to 0 PSIG or up to 250 F, the POCO Series 230 can be specified for a wide range of piping system requirements. Compared to competitive products, you will invest less money when specifying the engineered design and industrial quality of the POCO Series 230. Large Inventory Means Same-Day Shipment. We maintain the largest inventory of elastomeric expansion joints in the world. very size cataloged up to 72" is in stock in a variety of elastomers.

5 LIMI ODS & COOL ODS Figure 1: Limit od Figure 2: Control od Definition A control unit assembly is a system of two or more control rod units (limit rods, tie rods or compression sleeves) placed across an expansion joint from flange to flange to minimize possible damage caused by excessive motion of a pipeline. he failure of an anchor or some other piece of equipment in a pipeline can cause excessive motion. he control unit assemblies can be set at the maximum allowable expansion and/or contraction of the rubber expansion joint. When used in this manner, control units are an additional safety factor and can minimize possible damage to adjacent equipment. Use of Control Units with ubber xpansion Joints ubber expansion joints must be installed between two fixed anchor points in a piping system. he pipe system must be rigidly anchored on both sides of the expansion joint to control expansion or contraction of the line. Piping anchors must be capable of withstanding the line thrusts generated by internal pressure or wide temperature fluctuations. When proper anchoring cannot be provided, COOL UIS A QUID. Listed below are three (3) control unit configurations supplied by POCO and are commonly used with rubber expansion joints in piping systems. Figure 1 Known as a LIMI OD, this control unit configuration will allow an expansion joint to extend to a predetermined extension setting. uts shall be field set to no more than the maximum allowable extension movement of a rubber expansion joint. efer to ables 2, 3, or in this manual. Consult the systems engineer for proper nut settings prior to system operation. Figure 2 Known as a COOL OD, this control unit configuration is used to allow specified pipe expansion (expansion joint axial compression) and pipe contraction (expansion joint axial extension) movements. uts shall be field set to no more than the maximum allowable extension or compression of a rubber expansion joint. efer to ables 2, 3 or in this Manual. Internal and external nuts can also be field set to allow for no movement in the horizontal plane. his setting will allow the rubber to move laterally while keeping expansion joint thrust forces low on adjacent equipment. Spherical washers can also be furnished (upon request) to combat any potential nut to plate binding during offset. Consult the systems engineer for proper nut settings prior to system operation. Figure 3 Known as a COMPSSIO SLV, this configuration is used to allow for specified pipe expansion (expansion joint axial compression) and pipe contraction (expansion joint extension) movements. uts shall be field set to no more than the maximum allowable extension of a rubber expansion joint. efer to ables 2, 3, or in this manual. POCO will manufacture each compression sleeve to allow for no axial movement unless otherwise specified by the purchaser. sleeves shall be field trimmed to meet required allowable axial movement as set forth by system requirements. Spherical washers can also be furnished (upon request) to combat any potential nut to plate binding during offset. Consult the systems engineer for proper sleeve lengths prior to system operation. Important Control od Considerations he number of rods, control rod diameters and control rod plate thicknesses are important considerations when specifying control units for an application. As a minimum, specifying engineers or purchasers shall follow the guidelines as set forth in Appendix C of the Fluid Sealing Association s ubber xpansion Joint Division echnical Handbook (Sixth dition). POCO engineers its control unit assemblies to system requirements. Our designs incorporate an allowable stress of 65% of material yield for each rod and plate (rod and plate material to be specified by purchaser). herefore, it is important to provide pressure and temperature ratings to POCO when requesting control units for rubber expansion joints. It is also important to provide adjacent mating flange thickness or mating specifications to insure correct rod lengths are provided.
