When ordering an accumulator, the following information is required (not required for JG).For new ships:·Name of Shipyard·Hull NumberFor ships in service:·Name of Ship·IMO Ship Identification NumberFor offshore application: When applying the shipping classification survey for offshore application, please contact us in advance.Allowable Service Temperature (℃ ) ※1−10 - +70−10 - +110−35 - +70−10 - +70−20 - +80Symbol AreaCountryU.S.A.TAIWANFranceJapanMarineJapanU.K.South KoreaNorwayChinaX Special SpecialOther Special InspectionSelect the item number code corresponding to the material suitable for "service fluid" and "service temperature". ※1SymbolBladder CompoundStandard Nitrile RubberStandard Nitrile Rubber bladder with oil port valve molded inNitrile Rubber for high temperature useNitrile Rubber for low temperature useButyl RubberEthylene Propylene RubberChloroprene RubberEpichlorohydrin RubberFluorine RubberInspection·RegulationABSAmerican Bureau of ShippingCRChina Corporation Register of ShippingBVBureau VeritasMinistry of Land, Infrastructure, Transport and Tourism, JapanJGNKNippon Kaiji KyokaiLRLloyd's Register of ShippingKRKorean Register of ShippingDNVDNV ASCCSChina Classification SocietyNBRNBRH.NBRL.NBRIIREPDM Phosphate Ester Based FluidCRCHCFKMSuitable Service FluidTurbine Oil (jis K2213)Fatty Acid Ester FluidWater Glycol FluidW/o Emulsion FluidO/w Emulsion FluidBiodegradable FluidTap WaterSea WaterPhosphate Ester FluidBasic, Water※ 1 “Service Temperature” means the temperature of the fluid which contacts the bladder when it works. It is the accumulator's internal temperature.※ 2 O-ring material for gas charging valve, for connection port of SG vavle and Top Cap, and for built in SG valve is NBR.※ 3 When bladder compound is L.NBR, O-ring material for gas charging valve, for connection port of SG vavle and Top Cap, and for built in SG valve is also L.NBR.※ 4 Regardless of the bladder compound, material of seal washer for SG valve is NBR.※ 5 Please refer to page 104 ⑪ accessories supplied with bladder for further information.＊ Use over a long period of time at the maximum allowable service temperature should be avoided since it accelerates bladder deterioration. Use at 80% of the maximum allowable service temperature (70% in the case of horizontal installation) or less is recommended.＊ Fluorine rubber has excellent chemical resistance. However, be aware that the rubber swells with ether, ester, ketones, or methyl alcohol, hardens with anhydrous ammonia or activated amines, and is eroded by strong alkalis.＊ Note that use with petroleum based fluids may cause the extraction of unspecified substances from synthetic rubber (bladder and O-ring), resulting in fluid discoloration.＊ A button is located at the bladder bottom for J series accumulators. The standard bladder designation for the J series is "B".
