easy installation inflatable fender rubber dock fender for ship
docking
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.
