Product Description

Hot Sale Genuine Submarine Rubber Anti Collision High Pressure Hydro Pneumatic Fender
 

Submarines and other vessels that make contact below the waterline need a special fendering solution. HydroPneumatic fenders are filled with air and water, then fitted with a counterweight to stand vertically and protect submerged hulls.


Zhonghaike can also provide the special calculations for polytropic conditions(saturated airl,other air:water ratios, hull curvatures and other variables to predict exact performance of HydroPneumatic fenders.

   Safety and Reliability
 

Zhonghaike 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 Berthing
 

Ships 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 Tide
 

Zhonghaike 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.
