Pneumatic Floating Natural Rubber Fender,
Yokohama Natural Rubber Fender,
SGS Yokohama Pneumatic Fenders
Pneumatic rubber fenders have a long and successful history of protecting vessels in mooring operations. They are ideal for permanent and semi-permanent port applications and for offshore ship-to-ship transfers. Tough and resilient, rubber dock fenders are fast and easy to deploy, maintaining large clearances between the hull and the jetty or other vessel.
This serves to minimise damage potential during mooring. Critical properties of rubber fenders are energy absorption, hull pressure and reaction force. In both cases, Xincheng Marine Systems products score very highly, with low reaction force and low hull pressure.This means the fender absorbs significant energy, reducing the forces on both the vessel hull and jetty structures.
Construction of pneumatic fender
Pneumatic Fenders are constructed of three vulcanized layers each providing an important function in the construction and lifespan of the fender. The three layers are
(1) the inner rubber layer
The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.
(2) the tyre-cord layers of reinforcement
Synthetic tyre-cord layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and wear during bending, compression and stretching. The same compound isolates each thread within the layer.This greatly improves the ability of the fender to hold pressure, fatigue resistance and endurance life. Other reinforcing layer materials such as canvas have wear points that significantly reduce the life off the fender.
(3) the outer rubber layer.
The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.

1), safe for excess load marine depend on the ball
The reaction force of a floating pneumatic fender does not increase sharply even under excess load. Therefore, these fenders perform extremely well under such condation and as a result, protect ships and mooring facilities.
2), No deterration or variation in performance
Because pneumatic fenders utilise the compressive elasticity of air, performance deteriation due to fatigue is completely absent. The performance of these fenders remain unchanged at extremely low temperatures, even below - 50'C.
3), safety realiability
Xincheng pneumatic rubber fender are constructed using several layers of strong tyre cord are therefore extremely resistant to pressure and cutting, and are therefore extremely resistant to pressure and cutting. The larger size ( 2.5m dia upward ) are fitted with safety valve to prevent accident in the event of over copressiom.
The fender body is constructed of an inner rubber layer, reinforcing cord layers and an outer rubber layer. All three layers are bonded together by a combination of heat and pressure over a period of time in a vulcanising oven. Once completed, the fenders are pressure tested before relase.
To provide maximum strength and safety, the out skin of submarine fender is thicker than a normal surface fender.
The outer skin rubber compound is desinged and manufactured to be able to withstand both strenuous use and adverse weather. Condations whilst protecting the cord layers and inner rubber the cord layers are corranged at optimum angles designed to be completely airtight.
5), Simple and low cost installation
The weight of the fenders is supported by the water on which it floats, therefore, the fender can be morred simply by means of a guy rope or chain at minimal cost it can be removed easily to another quay or jetty when not use or transfeered to alternative mooring points as required
6), chain and tyre net
Almost floating fenders are protected by a chain and tyre net. The purpose of the chain and tyre net is to protec the fender body from damage by sharp objets or protrusions such as rough faced quay walls, to distribute sheer forces along the length of the chain net and to prevent the fender body from having to absorb them.
