Top Sale China Marine Yokohama Type Pneumatic Rubber Fender
1.Pneumatic Rubber Fender
Marine Pneumatic rubber fender is the advanced anti-collision
device for marine application in the world. Pneumatic Rubber Fender
also known as floating fender or Yokohama type marine rubber
fender, it is often installed on the terminal or ship, which aims
to absorb or reduce the collision energy between ship to ship and
ship to dock. This kind of product can protect the ship or dock
from the damage of collision.
Advantages pneumatic rubber fender:
1. Large compression deformation, low reaction force, high energy
absorption
2. Good floating performance, meet the needs of water level change
3. With compressed air as medium, the collision energy consumption
bu compressed air power
4. Easy installation and long service life
Structure marine yokohama rubber fender
1. Outer Rubber
Cover outside on the ball of rubber layer, which is used to protect
skeleton material and inner rubber ball from damage of external
force, the main features: high strength, wear resistance, ageing
resistance and tear resistance.
2. Synthetic cord reinforced rubber layer
Reinforced cord rubber layer is composed of winding Synthetic cord
layer, It is mainly used for maintain the internal air pressure,
which has good elasticity, no deformation and high power etc.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air
leakage and control the ball pressure.
4. Flange opening
The metal parts at both ends of fender, which can be fitted with
charging valve and safety valve.

3.Production Process
4.Quality
Marine 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.
The flange, the chain and the shackle are all made of hot-dip
galvanized, will not rust, the thickness is sufficient, and can be
used for a long time.
We have to be professional and mature in gluing technology, and the
surface of the fender is flat and smooth, and there is no air
leakage.
