ELAFLEX – EXPERIENCE YOU CAN RELY ONElaflex is a specialist company in safe connections forrefuelling and pipe equipment.Since 1923 we stand for values which are typical of afamily owned company: The spirit of innovation, reliability,continuity and flexi bility in thought and action.ERV expansion joints, co-developed with ContiTech, are animportant part of our product portfolio.The rubber bellows, co-developed with ContiTech, aremanufactured in Germany and assembled and distributedby Elaflex.We are a committed partner to our customers who count onquality engineered and durable products. Choosing ERVexpansion joints is a sound investment both in terms ofperformance and total cost of ownership.Service and Added ValueElaflex customers appreciate service factors such asprofessional technical advice, reliability, up-to-dateonline product information and global support by localElaflex distribution partners.Service also means the ability to supply a major partof our product range ex works with short lead times.A large 4500 sqm warehouse and a 1350 sqm workshopresult in an efficient delivery capability. More than25.000 bellows and a large number of flanges andaccessories are permanently available ex stock.According to customer specification, we supply theassembled product. Our modular system, developedover the years, is important both for efficiency and for06 Elaflex Rubber Expansion Jointssafe assembling. Bellows, flanges and accessoriesalways come from one source only and to the latestindustry standards. The combination of both modularsystem and control over the whole production chainsafeguard that everything fits perfectly.Our operational procedures also translate into betterservice. An up-to-date warehouse management systemhelps for good inventory accuracy and confirmation ofreadiness for delivery to the customer. Further, a 'pickby voice' and barcode-assisted stock managementminimise the possibility of incorrect deliveries andspeeds up the delivery process.Elaflex Rubber Expansion Joints 07

WHAT ARE RUBBER EXPANSION JOINTS?Rubber expansion joints are flexible connectors for the construction of pipe systems.They relieve system strain by reducing vibration and noise and compensate static or dynamic movementscaused by thermal change, load stress, pumping surges or construction settlement.They also compensate assembling inaccuracies (misalignment during installation) and can be used aspipe insert pieces to facilitate inspections.Standard lengthAxial compressionAxial elongationLateral offsetAngular offsetVibrationComparing Metal Expansion Jointswith Rubber Expansion JointsRubber expansion joints show no fatigue failure due to high frequenciesof vibration are not endangered by stress corrosion crackingdue to their higher flexibilty are suitable for a larger range of media due to theiravailable type variety08 Elaflex Rubber Expansion Joints will absorb outer physical influences, e. g. accidentalimpacts without any damage can be used to protect the pipework against high shockstress offer max. movement ranges, at the same time they arevery compact (short installation length) are suitable to substantially reduce vibration and noiseElaflex Rubber Expansion Joints 09

WHY YOU SHOULD CHOOSE ERV.Optimal Shape and Construction of the BellowsSuperior Life Time Large axial, lateral and angular range of allowable HiTech rubber compounds from ContiTechmovement, no double sphere necessaryERV expansion joints from Elaflex are moulded single sphere type rubber bellows with swiveling metalflanges. Their construction and lengths (installation sizes) have since become internationally recognisedstandard. Low reaction forces and low inherent resistance Noise dampening: the major part of thepiping's structure-borne noise and the low-frequencynoise generated by fluids is eliminated Vibration dampening: ERV efficiently absorb vibrationscaused by engines, turbines or compressors Physical properties of compounds and reinforcementsare optimised for each bellows type :elongation at break, ozone and UV resistance,cold flexibility, tensile strength, volumetric extension etc. Permanent testing of raw material properties –before and during production Rubberized reinforcements for superior adhesionof all layersSwiveling flangeswith smooth holesfor boltsExperience and Know HowLiner (tube) Applications since 1956 Useful division of labour and competence betweenContiTech, one of the leading international rubber productmanufacturers (bellows production) and Elaflex Integrated sealing surface with type matched steel wire core Made in Germany, Elaflex / ContiTech quality pilosophy High operational safety, 1 : 4 safety factor regardingburst pressure(know-how regarding flanges, accessories, assembling,Integrated sealingsurface withsteel wire corecertification, testing and distribution)Cover Consistent suppliers and manufacturing methods ensure aconstant qualityLarge Product Range Variety of 13 different types, sizes 1" – 40"( DN 25 – 1000 mm ), various lengths and a vast choiceof flange type  / material and accessoriesReinforcementCustomer Focus Large warehouse of bellows ( 25.000 bellows permanentstock ) and flanges / accessories ensure short lead timesStabilisingrimfor standard types Technical service : professional advice, documentation,testing certification (audited to European PressureEquipment Directive) Online ERV configurator: http://ervconfigurator.elaflex.dehelps to find and visualize the required product in a fewsecondsThe Bellows International quality reference for some applications,e. g.
