High Pressure Underwater Air Lift Bags , Heavy Duty Air Bags For Caisson
Ship Launching / Landing Airbags, basic body are consisted of our 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
The outer rubber layer protects the cord layers from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black.
2. Synthetic-net-cord layer for reinforcement
The reinforcement cord layers, which are 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.
3. End Fittings
End fittings include air tightness swivel and airbags safety air inlet.
airbag features
1. Big carrying capacity
2. High capacity against compression and twisting
3. New design of anti-bursting contruction at the end
4. Optimized structural layout
5. Durable aging resistance and anti-wear characteristic
6. Higher flesibility and damping capacity.

Specifications:
1. The standard specification of airbags.
You can choose the required diameter and effective length to meet your projects.
*Diameter (D): from 0.8m to 2.0m.
*Effective Length (EL): from 6m to 18m.
*Total Length (TL): from 7m to 19.5m
The above specifications only are our standard specifications arrange. Can be supplied customized size upon customers’ request.
2. The standard number of layers
The number of layers, which mean the number of Synthetic-tyre-cord layer, usually, our airbags contain 4, 5, 6, 7, 8, 9 layers types. Other type is still available upon your request to confirm the Safety Working Pressure.
