Composition of marine airbag
consist of rubber layers, synthetic-cord-reinforced rubber layers, are kind of a cylindrical airbags with hemispherical heads at the both ends. All of these are vulcanized together, and then compress air inside to enable it to roll.
1. Outer Rubber layer
protects the cord layers from abrasion and other external forces.
2. Inner rubber layer
Seals pressurized air inside airbag
3. Synthetic-net-cord layer for reinforcement
made of Synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
4. End Fittings
End fittings include air tightness swivel and airbags safety air inlet.
Application of marine airbag
1.ship launching, lifting and refloating
2.floating bridge and dock construction
3.rescue and remove of wrecked ship
4.setting up temporary pontoon bridge pier and water transport channel
5.blocking debacle of anti-flood and anti typhoon dam
6.applying to short distance transport of the bridge, concrete piers, drilling equipment.
The airbags should be maintained in a dry ventilated room and be protected from light. acids, alkalis, oils or organic solvents, heat source. should be in a relaxed condition free from tension, compression or other deformation.
