ISO17357 Standard Pneumatic Rubber Fender For Marine And Boat
Product Introduction:
Pneumatic Rubber Fender is Designed for sealing and blocking sewers, drainage systems, pipelines, and gullies in which the backpressure exceeds the range of standard stoppers.
1. Outer rubber
Rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces
2. Inner rubber
Liner of a rubber membrane that seals the pressurized air inside the fender
3. Synthetic-tyre-cord layer for reinforcement
Layer made of synthetic-tyre-cord fabric, which maintains the internal air pressure of the fender
Note 1 to entry: As the main fibres of the synthetic-tyre-cord fabric are not braided like synthetic canvas fabric or synthetic belt fabric, there are advantages for its fatigue-resistance performance and pressure-holding performance. .
4. Flange opening
Steel flange which is mounted on the fender, to which an air valve or safety valve can be adapted
5. Guaranteed energy absorption
Energy that the fender can absorb without permanent deformation or failure
6. Reaction force
Force produced by a fender reacting to a compressive force
Note : It is equal to the force of the air pressure of the fender multiplied by the contact area of the fender to the ship or berthing structure.
Specificaton of Pneumatic Rubber Fender:
Initial internal pressure : 50kPa or 80kPa.
