Style 1101ER is aneconomic and space-saving way to combine aneccentric pipe fitting withan expansion joint.

Style 3303 - MoldedTeflon® design offerssuperior chemicalresistance with lowdeflection forces.

Features and Benefits:ABSORBS ALL DIRECTIONAL MOVEMENTGeneral Rubber’s Maxi-Joint® wide arch expansion joints providesuperior movement capability in axial compression, axial extension,and lateral deflection, as well as in the angular and torsional direction.This performance cannot be obtained with metallic joints, groovedcouplings, or large pipe loops. The low stiffness and deflection forcesmake designing with General Rubber expansion joints a breeze.

REDUCES NOISE AND VIBRATIONGeneral Rubber’s expansion joints and flexible connectors effectivelydampen and insulate against the transmission of noise and vibrationgenerated by mechanical equipment. This is particularly importantin HVAC applications where the disturbing frequency of pipe andfluid-conducting noise can resonate and amplify throughout thebuilding. Metallic joints and grooved couplings do little to reducenoise and vibration.

HIGH RESISTANCE TO SHOCKThe highly compliant and resilient characteristics of General Rubberexpansion joints make them ideally suited for earthquake and bombblast isolation, as well as pressure-surge and water hammerdampening.

RELIEVES PIPE AND ANCHOR STRESSThermal movements along with other external forces and displace-ments, including ground settlement can quickly exceed allowablepipe and anchor stresses. General Rubber expansion joints absorbthese stresses and replace them with their own low stiffness(spring rate).

COMPENSATES FOR MISALIGNMENTIt is common in both new construction and replacement applicationsto encounter pipe misalignment. Minor misalignment can be takenup with standard General Rubber expansion joints, and customunits can be quickly fabricated with large permanent offsets.

PROVIDES ACCESS TO PIPING AND EQUIPMENTAccess to piping and equipment can be easily achieved bytreating the expansion joint as a removable spool piece. If aself retracting design is needed, General Rubber’s Style 1101DJdismantling joint can be utilized.

COST-EFFECTIVE SOLUTIONAn optimal design does not necessarily mean higher pressure ortemperature ratings, because these features typically increase theproduct’s stiffness and cost. With a proven track record that datesback to 1950, General Rubber has the experience and is confidentthat we can develop an optimal and cost effective solution to meetyour requirements. Our abrasion and corrosion-resistant materialscan be superior to even the most exotic metals. Our large inventoriesand modern U.S. ISO 9001 certified manufacturing facility alsomean quick deliveries, as well as top quality products and services.

Materials of Construction:EPDM—Outstanding water, vapor, and weather resistance. Goodresistance to heat, ozone, alkalis, sunlight, and oxygenated solvents.Ideal for outdoor service. Do not use with petroleum oil service. Goodgeneral purpose elastomer with an effective operating range from-30ºF to 350ºF.

NEOPRENE—Resists alkalis, inorganic acids, and salt solutions.Flame-retardant, as well as abrasion and weather resistant. Goodresistance to animal and vegetable oils; moderate resistance topetroleum oils. Effective operating range from -20ºF to 225ºF

CHLOROBUTYL—Lowest permeability, very good resistance to water,heat, fats, ozone, alkalis, sunlight, abrasion, and oxygenated solvents.Effective operating range from -30ºF to 300ºF with brief allowableexcursions to 350ºF.

HYPALON®—Offers superior weather resistance, flame retardant,good abrasion resistance, and excellent resistance to acids, alkalis,and oxidation. Effective operating range from -10ºF to 250ºF.

BUNA-N (NITRILE)—Good resistance to mineral and vegetable oils,greases, hydrocarbon solvents, dilute acids, and alkalis. Effectiveoperating range from -10ºF to 210ºF.

HNBR (HYDROGENATED NITRILE)—Has a wide service temperaturerange from -40°F to 302°F and resistance to fluids of various chemicalcompositions, as well as excellent resistance to alkaline and aggressivefluids. HNBR also has improved wear and abrasion resistance andimproved ozone resistance of up to 5 times that of standard NBR/Buna-N. It uniquely bridges the gap in oil applications where thetemperature was too high for NBR/Buna-N and otherwise forced theuse of the much more expensive FKM compound.

PURE GUM RUBBER—Excellent resilience and rebound elasticitywith high tensile strength. Excellent resistance to tear and abrasion.Effective operating range from -40ºF to 180ºF.

PTFE FLUOROPLASTIC:—Superior chemical resistance, completelyinert to nearly all industrial chemicals and solvents. Effective operatingrange from -60ºF to 450ºF. Teflon® is used when indicated or specified.FDA Food-Grade Service:Several white and black elastomers meetFDA requirements and can be used in direct contact with food,beverage, and pharmaceutical products.

VITON®—Excellent resistance to aggressive chemicals, solvents,and halogenated hydrocarbons. Viton® TBR-S provides excellentresistance to steam, aqueous acids, amines and concentratedcaustics/bases/alkalies. Viton® ETP-S offers the most universalchemical resistance and has excellent flexibility at low temperatures.Effective operating range from -10ºF to 400ºF.

REINFORCEMENTS—Polyester, Nylon, Kevlar®, fiberglass, andsteel. Temperature rating is dependent on both elastomerand reinforcements.

1.) Maximum Control Unit lengths and diameters, as well as gusset thickness, are meant to assist in determining adequateclearance and mating hardware selection. The values are maximum values and are based on mild steel design.Dimensions will change when using high tensile steel and with different arrangements. Contact General Rubber andrequest a specific submittal drawing for your job.

2.) Expansion joints should be installed between anchors. Anchors should be located at changes in pipe direction and guidesshould be spaced according to industry standards. Piping must be supported so the expansion joints do not carry anypipe weight. Contact General Rubber for more details.

Notes:1.) Extension movement capabilities can be increased with additional pre-compression during installation.2.) Anchors should be used to resist the pressure thrust force and isolate the thermal movements between expansion joints.3.) For vacuum or large pre-compressed applications, a set-back may be required to keep the expansion joint from protruding into

the gas stream or touching the flow liner/baffle.

4.) Retaining Rings/ Backing Bars of 1/4" thickness standard. – Suggested bolt spacing at 4" centers max.5.) For full product specifications and installation instructions, see SPEC 1092-1 and 1097-1 and ININ 1092-1 and 1097-1.

The General Rubber AdvantageHigh-quality General Rubber products solve problems in a remarkable number ofapplications, from electric boats to paper mills to major resort hotels. We havebeen audited and approved for use by the Nuclear Procurement Issues Committee(NUPIC). Nuclear and other power generating facilities select General Rubberbecause performance and reliability are critical.

As the pollution abatement and waste water treatment industries came of age,General Rubber responded by developing corrosion and abrasion-resistant prod-ucts to meet their specific requirements. Similarly, chemical processing plants,paper mills, and mining operations have learned that they can depend on GeneralRubber products.

Milwaukee Park Stadium and many other commercial and industrial venues useGeneral Rubber vibration control products for their heating, ventilation, and airconditioning (HVAC) systems to relieve stress and absorb objectionable noise andvibration. Ships, including the USS Cole, use General Rubber expansion joints tosave space, reduce noise, and isolate vibration.

The General Rubber customer commitment is evident in every aspect of our busi-ness. Our sales team includes engineers who are prepared to discuss the intrica-cies of the application. They know what questions to ask to identify the best solu-tion at the best price. If an effective solution cannot be obtained from our exten-sive product line, our professional engineers will custom design a solution optimalfor your application. This willingness to search for answers is deeply ingrained inour customer commitment and lies behind our tradition of releasing new andinnovative products each year.

Handling your toughestapplications since 1950.

POWER GENERATIONGeneral Rubber products are used on condenser water boxes,cooling towers, steam turbine exhaust lines, cooling water lines,scrubber units, and FGD systems.

WATER AND WASTE TREATMENTFlexible connections and pinch valves are required on sludgeand grit pumps, digesters, aeration systems, blowers, odorcontrol, and methane gas ducting.

CHEMICAL PROCESSINGExpansion joints and pinch valves of chemical-resistant materialsare required on caustic chemical pumps, digesters and scrubbers,and are found throughout the piping and ducting system.

PAPER AND PULPBleaching systems and lines containing white, black, and greenliquors require chemical-resistant General Rubber productsalong with the pulp slurry pumps and scrubber units.

HVACPump connectors and other noise vibration control products willreduce noise and vibration generated from mechanical equip-ment, including pumps, chillers, compressors, fans, heatexchangers, and cooling towers. They are also used to absorbthermal movements and vibration in risers and other pipelines.

MININGThe extremely abrasive slurry in tailing lines requires Pure GumRubber expansion joints and pinch valves. The ducting also oftenrequires chemical-resistant flexible connections.

MARINEShipboard piping and ducting utilize Neoprene connectors builtto Coast Guard, ABS, and ASTM F-1123-87 standards. Executive Vice President Amy Hammarstrom

General Rubber's President,Lloyd B. Aanonsen, is a licensedengineer with an MBA. He hasbeen designing and developingnon-metallic expansion joints andother mechanical rubber productssince 1987, and has published anumber of articles on the subject.He has also completed multipleterms as chairperson of theFluid Sealing Association'sExpansion Joint Division.

Maxi-Joint is a brand under General Rubber Corp. representingour comprehensive line of expansion joints, flexible connectors,rubber flanged hoses and related accessories, as well as sprayshields and penetration seals. These products provide criticalfunctions in piping and ducting systems.Since our inception in 1950, General Rubber Corp. has designedand developed a wide range of mechanical rubber productsused in the most demanding applications. Rubber is one of themost compliant and resilient materials available. This not onlymakes it an ideal material for car tires, but also for expansionjoints and flexible connectors. With a flexing cycle life in thetens of millions, fatigue is simply not a design concern.Improved performance and engineered solutions are oftenaccomplished by incorporating advanced materials and tech-nologies to what otherwise would be considered a conventionalproduct line. This benefits both the specifying engineer design-ing an optimal system, as well as the customer performingmaintenance on, or upgrading an aging system.Piping and ducting systems require support and flexibility ascritical design elements. The obvious consequence of inade-quate support is catastrophic system failure that can also be lifethreatening. It is less obvious however, that inadequate flexibilitycan produce the same devastating consequences. System flexi-bility is required to absorb thermal movements, ground settle-ment, misalignment, vibration and shock. The features and ben-efits of our expansion joints include absorbing these forces anddisplacements, and replacing them with the expansion joint’slow stiffness (spring rate). In addition, our products absorb noiseand vibration, as well as provide easy access to piping andequipment. Applying expansion joints to your system is the sub-ject and title of the linked article published in Pumps andSystems magazine. It remains a good reference for understand-ing piping system requirements and basic expansion joint func-tions, including the role of control units in anchored and un-anchored systems.Improved performance is directly related to our materials ofconstruction and design. We utilize industry leading constructionmaterials including premium elastomeric compounds, tire cordand high tensile steel reinforcement. Utilizing tire cord is a goodexample of optimizing a design with advanced materials. Thetire cord is engineered with a Resorcinol-Formaldehyde Latex(RFL) coating for superior bonding to the rubber. The cordsthemselves can be aligned on an optimal bias ply angle, offeringtailored strength in the directions needed. This virtually elimi-nates delamination and reduces the total number of pliesrequired. The result is improved performance in the form ofincreased movement capability and decreased spring rates, aswell as improved reliability.

Style 1101CR is aneconomic and space-savingway to combine a concentricpipe fitting with anexpansion joint.

Style 1082 Slip-On typewith double arches allowsfor maximum movement

with minimum cost.

New design features in piping expansion joints is the subject and titleof the linked paper presented at The American Power Conference. Italso remains a good reference for understanding the incredible per-formance improvements that can be achieved when advanced mate-rials and technologies are utilized.

Engineered solutions are also directly related to our many years ofexperience and understanding of demanding applications. For exam-ple, supplying high pressure and self retracting expansion joints onoffshore mooring platforms provided us with the understanding to dothe same on a massive scale for the CCWP project in Qatar. This proj-ect required hundreds of much larger diameter high pressure dis-mantling expansion joints. We are proud of an environmental awardwe earned from the Fluid Sealing Association and ChemicalEngineering magazine for submitting the linked case study on thisproject. Similarly, supplying original equipment into many nuclearpower plants has also provided us with the opportunity and ability toupgrade both metal and rubber expansion joints for higher perform-ance and greater reliability. In general, replacement and retrofit workoften requires building the product to existing field dimensions,including permanent offsets caused by ground settlement, unre-strained thrust forces or equipment substitution. The custom fit unitis easier to install and will have a longer maintenance free life.Utilizing improved materials and designs will also improve the prod-uct's service life and reliability as well. We are experienced at obtain-ing the relevant field information and producing an optimal productfor that application.

Maxi-Joint expansion joints and flexible connectors provide criticaldesign elements in piping and ducting systems. The experience andcapability of General Rubber can effectively utilize these products ineven the most demanding applications. In consideration of our prod-ucts, you are assured that every aspect of your project will be ourpriority.

Thank you for your consideration.
