Single Shpere Flexible Rubber Joint

Flexible Rubber JointSpecification:1.24 years manufacturing experience2. ISO9001, ISO140013. Import rubber4. China National Standards Drafting Unit of Rubber Joint5. Qualified Joint Supplier in Nuclear Power Plant1) Product PerformanceLIWEI Flexible Rubber Joint are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, and compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.Flexible Rubber Joint is a single sphere design with less length, the supply range is from 32mm to 3600mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.2) Application RangeEquipped with the excellent comprehensive performances of flexible rubber joint, LIWEI Flexible Rubber Joint can be used for lift and transportation of raw water and sewage, transportation of water supply, cooling cycle water of thermal power plant, condensate water of metallurgy industry and chemical materials of chemical industries, cooling and dilution of oil and chemical industries and flexible connection of other industries.LIWEI Flexible Rubber Joint is also suitable to transport all grain and powder material and gas for its high abrasive resistance.In addition, special notifications are hereby conducted for design units and clients so as to ensure the project quality. Please note to install anti-break stop device, if Flexible Rubber Joint are designed to install close to pump exit nozzle and pipes' corner. If your pipes need to be buried, please use our patent-buried protective devices. In a word, remark requirement for use, and we will provide satisfactory service to you.3) Features and Benefits1, Versatile hand-built construction. Made in China2, Absorbs directional movement3, Absorbs vibration, noise and shock4, Compensates for misalignment5, Wide flowing arch design6, Virtually eliminates sediment buildup7, Economical fully molded construction8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes9, Special grooved flange ring design, prevent rubber end pull out10, Solid galvanized steel floating flanges speed the installation time11, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings12, No gaskets required; Integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JISNote:1. The Liwei Flexible Rubber Joint with Flanges supply range is from DN32 to DN3600.2. Control units must be used when piping is not properly anchored.3. The rated pressure 2.5MPa products will only be sold with control units.4. The Liwei Flexible Rubber Joint with Flanges Pressure rating is based on 30° C operating temperature. The pressure rating is reduced at higher temperatures.5. Movements shown in the above table are non-concurrent.6. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.7. Please remark the application standard of structural strength and connection size when placing an order.8. If the relevant parameters of flexible rubber joints needed are not within the scope of the foregoing list, please remarks. We can design and manufacture on behalf of youDelivery time:Within 30 days after receipt of the deposit, or as your requestPackaging details:Unfumigation wooden case (out package) and plastic film and textile membrane(inside package). We can make change as your request.Materials listNONameMaterial1Inner rubberIIR\CR\EPDM\NR\NBR2Outer rubberIIR\CR\EPDM\NR\NBR3Framework layerPolyester cord fabric4FlangeQ2355Reinforcing ringSteel wire rope Physical and Mechanical Properties FormNoItemIndexTest valueInner rubberOuter rubber1≥Tensile strength(MPa)121313.62≥Break strength (%)4505005643≤Break permanent deformation (%)2530224≤Brittleness temperature-30-30-405≥Viscosity(KN/m)2.02.05.66Aging hot air   (100degree×48h)Tensile strength change (%)+25~-25+25~-2520Tensile rate change (%)+10~-30+10~-3057≥Acid resistant10%H2SO4×168h0.70.70.858≥Alkali proof10%NaOH1×68h0.70.70.85 Technical ParametersDNDiameterFF Length(mm)Axis displacementRadialdisplacementDeflexiondisplacementType-IType-IIType-IType-IIType-IType-IImminchExtensionCompressionExtensionCompression321¼″906109±7.5°401½″957109±7.5°502″10571010±7.5°652½″11571311±7.5°803″13581512±7.5°1004″150101913±7.5°1255″165121913±7.5°1506″180122014±7.5°2008″210162530352225±7.5°±10°25010″230162530402225±7.5°±12°30012″245162530402225±7.5°±12°35014″255162535452230±7.5°±12°40016″255162535452230±7.5°±12°45018″255162536472230±7.5°±12°50020″255162536482230±7.5°±12°60024″260162540502233±7.5°±12°70028″260162540552233±7.5°±12°75030″260405533±12°80032″2601625455522±7.5°±12°90036″260162545552235±7.5°±12°100040″260162545602235±7.5°±12°110044″300456035±7.5°±12°120048″300162550602438±7.5°±10°130052″300506038±10°140056″350507040±10°150060″350607040±10°160064″350182560702446±7.5°±10°180072″400182560752448±7.5°±10°200080″450707550±10°220080″400707550±10°220088″500708060±10°240096″500808060±10°2600104″500858060±10°2800112″550858060±10°3000120″550858060±10°
