Product Description Products Description Jerryborg JRB pneumatic fenders are manufactured according to ISO17357-1:2014.Fenders are available in diameters ranging from 300 mm to 4,500 mm and lengths ranging from 500 mm to 12,000 mm, as well as special sizes. A versatile and well proven design. JRB pneumatic fenders are available as sling type or with chain &tyre nets to suit a variety of inshore and offshore applications. ? ISO 17357 certified? Guaranteed energy absorption? Low hull pressures? Chain tyre net and Sling type? Thick skin construction? Good angular performanceSafety and ReliabilityJerryborg Pneumatic Rubber Fenders are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders.Advantages at Inclined BerthingShips usually make initial contact with the dock or another ship on STS operations at an oblique angle. In the case of solid rubber fenders or foam fenders, rated reaction force and energy absorption decreases considerably at inclined compressions compared with parallel compression. In order to compensate for the decrease of energy absorption at inclined compression, it is necessary to use larger sizes in the case of solid rubber fenders or foam fenders. Distribution of load is also comparatively even because of the molecular freedom of air and high flexibility of the multi-layered cord-reinforced rubber membrane. This makes the body of a pneumatic rubber fender more shape conformant compared to solid or foam fenders, and thus able to better distribute the load along the hull of a ship or jetty structure during inclined compression.Adaptable to the TideJerryborg Pneumatic Rubber Fenders basically float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement. This means that energy absorption always takes place at the most suitable position, and that only one fender is required per dolphin.Installation DimensionsSizeABCDEFφ1000 * 1500L97595013502003752000φ1200 * 2000L1200114016202204302600φ1500 * 2500L1525142020502505253250φ2000 * 3500L2050190027003006504500φ2500 * 4000L2490238033804508905200φ3300 * 6500L33803140446050010808500φ4500 * 9000L471042706180800147012000Performance TableDia. xLength(mm)Initial internal pressure 50KpaInitial internal pressure 80KpaReactionForce(KN)EnergyAbsorption(KN.M)HullAbsorption(Kpa)ReactionForce(KN)EnergyAbsorption(KN.M)Hull Absorption(Kpa)500 *1000646132858174600 * 10007481269811166700 * 150013717135180241771000 * 150018232122239451601000 * 200025745132338631741200 * 200029763126390881661350 * 25004271021305611421701500 * 30005791531327612141741700 * 30006391911288402671682000 * 350087530812811504301682500 * 4000138166313718159251802500 * 55002019943148265313171953300 * 450018841175130247616401713300 * 650030151814146396125321913300 * 1060052573067158690742812084500 * 900057474752146755166331924500 * 1200079846473154104909037202 Company ProfileLies in Qingdao, a beautiful coastal city with red tiling and green trees, blue sea and clear sky, Qingdao Jerryborg Marine Machinery Co., Ltd is a high-tech enterprise integrated with manufacturing, research and innovation, technical services,specialized in manufacturing marine products, such as marine rubber fender, marine airbag, navigation mark and marine buoy.
