Pneumatic Fender Factory Price , Marine Airbag Fender For Ship Protection
There are two types of floating fenders. Calls pneumatic fenders (FLN), ie air fenders whose interior is pressurized air and the foam floating fenders (FLE), whose interior consists mainly of a closed pore polyethylene being crosslinked its exterior comprises a polyurea elastomer. Both types can carry external protection based on chain & tyre netting.
Fender structure
Floating pneumatic rubber fenders can be easily handled and installed with guy-rope or guy-chain because of their lightweight. It can resist the shearing force and maintain energy absorption level under inclined compression up to 15 degrees. Meanwhile, provide the low and comparatively even hull pressure.
Consisted of several synthetic-cord layers and tough abrasion-resistant rubber, they have consistent performance even under rough conditions and cyclic load. The maintenance cost and damage risk are minimized too. The best material also ensures self-buoyancy and an extremely long service life.
Outer Rubber
The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.
The diagram below shows the actual properties as specified in ISO 17357. Generally, the outer rubber is black, but other colours such as grey and off-white can be supplied upon request.
Tyre-cord Layer
Synthetic tyre-cord layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and
wear during bending, compression and stretching. The same compound isolates each thread within the layer.
This greatly improves the ability of the fender to hold pressure, fatigue resistance and endurance life. Other reinforcing layer materials such as canvas have wear points that significantly reduce the life off the fender.
Inner Rubber
The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.
