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.
4). Construction
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.
