The submarine fender is filled with water and air, and there is a counterweight under the fender, which can be erected in the water.
Introduction:
The Submarine Foam Fender is a special version of the aerodynamic fender developed for submarines.
The submarine fender is filled with water and air, and there is a counterweight under the fender, which can be erected in the water. The Hydro Pneumatic Fender is designed to be installed vertically, so it is very suitable for submarines or submarines whose impact point may be below the waterline. Vessels, such as catamarans, semi-submersible platforms and drilling rigs, protect submarines and other ships that come into contact below the waterline.
The submarine fender can adjust the performance of Henger Hydro aero fenders by changing the initial pressure, the ratio of water to air and the ballast weight to adapt to the hull curvature and sensitivity of the latest submarine.
Hydro-pneumatic fenders can be installed on most wharf structures and have various sizes to suit various submarines and various wharfs.
Submarine Foam Fender Composition:
1. Outer rubber of submarine
The outer rubber layer covering the outside of the fender protects the cord layer and the inner rubber from wear and other external forces. The compound has sufficient tensile strength and tear strength to withstand any weather conditions and arduous use. The standard color is black, but other colors are available upon request.
2. The inner rubber of the submarine fender
The rubber membrane lining seals the compressed air inside the fender so that its performance will not be weakened. .
3. Submarine fenders are used to reinforce synthetic tire cord layers
The reinforcement layer is made of synthetic tire cord commonly used in tires, arranged at an ideal angle to maintain internal pressure and evenly distribute stress, thereby providing a powerful and effective reinforcement.
4. Swivel shackle for submarine fender
A steel ring is placed on one end (or both ends) of the fender, one end is fixed to the underwater counterweight, and the other end is fixed to the dock.
5. The flange of the submarine fender
A steel flange is installed on the mudguard, and an air valve or safety valve can be installed.
6. Safety valve for submarine fender
Submarine fenders with a diameter of 2500mm and larger should be equipped with safety valves to release excessive internal pressure when the fender is accidentally over-compressed. This invention reduces fender wear and is the safest way to prevent The method of explosion.
7. Metal fittings of submarine fender
All relevant metal fittings of the pneumatic fender, including shackles, towing rings, swivels, chain nets, are made of stainless steel, which can resist seawater corrosion.

Deep Draft Submarine Camel Fender storage:
1. When the inflatable rubber fender is not used for a long time, it should be cleaned and placed dry, filled with appropriate compressed air, and placed in a dry, cool, and ventilated place. Keep the stock temperature at -15℃-40℃.
2. The storage location of submarine fenders should be far away from heat sources.
3. Submarine mudguards must not be in contact with acids, alkalis, greases and organic solvents.
4. When the fenders are not used, they must not be stacked, nor must they be stacked on the dock. In order to better extend the service life of pneumatic rubber fenders, it is recommended to store them strictly in accordance with the above recommendations.
