Pneumatic rubber fender without protection net




Pneumatic Fender without protection net is designed without protection net. Compare with net type pneumatic 

fenders, this pneumatic fender has lower weight. This type pneumatic fenders are well suitable for the  ship-to-

ship or ship-to-quay operation. And better for the ship hull allowed lower hull pressure.


Everblue Maritime Pneumatic Fender without protection net is fully comply with the durability test required by 

ISO17357. 

The test shall comprise at least 3000 repetitive cycles of parallel compression from the original diameter to the 

maximum deflection. After 3000 repetitive cycles, there shall be no cracks and other harmful defect on any part 

of the fender. No reduction of the guaranteed energy absorption(GEA) shall be accepted.


Advantages of Pneumatic rubber fender without protection net


Stronger Fender Wall

Everblue Maritime Pneumatic rubber fender without protection net are manufactured comply with the material 

requirements of ISO 17357 completely.    

And manufactured by model technology, which is different with general Chinese pneumatic fenders.

Easy to Transport and storage

Everblue Maritime Pneumatic rubber fenderwithout protection net is easy to handle because of their lightweight. 

They also can be deflated completely, easy to storage. 

The big size pneumatic fenders over 2500mm diameters can be loaded into the normal container easily to save 

shipment.


Construction of Pneumatic rubber fender without protection


Pneumatic rubber fender without protection net shall consist of an out rubber, synthetic-tyre-cord layer, and inner 

rubber vulcanized firmly.

● The out rubber are used to protect the cord layers and inner rubber from abrasion and other external forces.

This rubber compound have sufficient tensile and tear resistance strength to withstand anticipated weather conditions 

and severe usage.

●  The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fender

●  The inner rubber layer seals the pressurized air inside the fender

●  Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when 

the fenders are over-compressed accidentally.


Floating fender test 




Acceptance testing and inspection for purchased floating pneumatic rubber fenders shall be based on the test

inspection indicated below:

Material test of rubber — Conducted in accordance with the Physical properties of inner and outer rubber 

required  by ISO 17357:2002

● Dimensional inspection — shall be inspected at the initial internal pressure. Tolerance: +10%, -5%.

●  Air-leakage test — shall be conducted at initial pressure for more than 30 min

●   Hydrostatic-pressure test — shall be performed for 10 min at the hydrostatic pressure shown in “test pressure 

at 0% deflection”. Maximum temporary elongation: 10%
