Payment & Shipping Terms:
|Application:||Protect The Dock And Body Of Vessel||Type:||Round Pneumatic Rubber Fender|
Pneumatic rubber fenders shall consist of a cylindrical air bag with hemispherical heads
at both ends,which shall be filled with compressed air.The basic rubber fender body construction
of this fender shall consist of an outer rubber,synthetic-type cord layers for reinforcement
and an inner rubber.All of these should be vulcanized.
NOTE:Alternative reinforcement methods for synthetic-type-cord layers may be considered
if their strength and durability are designed and proven to be equal to,or superior to,the synthetic-type-cord layers after exhaustive trails.
2.The outer rubber shall protect the cord layers and inner rubber from abrasion and other external
forces.This rubber compound shall have sufficient tensile and tear resistance strength to withstand
anticipated weather conditions and severe usage.This rubber shall satisfy the values specified in Table3.
3.The inner rubber layer shall seal the air inside.It shall satisfy the requirements specified in Table 3.
4.The inner reinforcement synthetic-tyre-cord layers shall be strong enough to hold the internal pressure.
In both compressed and non compressed situations,the fender’s endurable pressure shall be as in Table 4 or Table 5.
5.The flange opening shall be at either end,or both ends,for convenience of air charge and water filling,if required.
6.The end of the reinforcement-cord layers shall enter the bead ring and be turned up outside
the bead ring,which is built-in at the flange opening.
7.Fenders of diameter 2500mm and larger shall be equipped with a safety valve for releasing excess
internal pressure when the fenders are overcompressed accidentally.Fenders which are smaller
than 2500mm in diameter,can be equipped with a safety valve if required.
8.The fender shall be equipped with an air valve for inflation and checking air pressure.
