International standard Marine Fender
1.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 withst and anticipated weather conditions and severe usage.
3.The inner rubber layer shall seal the air inside.
4.The inner reinforcement synthetic-tyre-cord layers shall be strong enough to hold the internal pressure.In both compressed and non compressed situations.
5.The flange opening shall be at either end, marine fender 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 plastic marine fender 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, marine rubber fender can be equipped with a safety valve if required.
8.The fender shall be equipped with marine fenders an air valve for inflation and checking air pressure.
- TypeⅠ(net type) shall be covered by a chain net, boat fenders wire net or fiber net. Each end of longitudinal chains,
wires or fibbers shall be linked together with one or two rings,which shall be connected with a guy-chain or guy-rope. Usually, marine fenders international these nets will be fitted with used tyres or rubber sleeves to provide additional protection to marine fenders international the fender body polyform fenders .
- Type Ⅱ(sling type) fenders shall have a lifting device on each end, which shall be connected with a guy-chain or guy-rope.Pressure requirements. It is the advanced anti-collision device for marine application in the world today. It uses compressed airbag as medium to absorb the impact energy when ship-to-ship contact. It uses compressed air as medium to absorb the impact energy when ship-to-berthing.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,Qingdao Haozhiyue Marine System’s fenders are fast and easy to deploy, maintaining large clearances between the hull and the jetty or other vessel.
