1. Construction Features of Airbags

Marine Airbags have the best designed structure which consists of five different functional membranes in rubber layers.

1) Outer Rubber Layer

The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.
2) Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
3) Synthetic-Tire-Cord Layer as 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 distribute stress evenly. So they can provide strong efficient reinforcement.

2. General Dimensions of Airbags

Diameter: 0.8m to 30m

Length: 7m to 20m

In order to confirm airbag's safety working pressure, we define the number of layers, which means the number of synthetic-tire-cord layers. Normally we offer marine airbags with 3, 4, 5, 6, 7, 8, 9 layers. Other types are available upon request.

3. Performance Calculation Principle of Airbags

The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.

Because of the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.

The approximate bearing capacity can be calculated as follows:

F=PS
S=π x (D1-D2)/2

Mark:
F: Bearing capacity

P: Inner pressure

S: Contact area

D1: Diameter of airbags when free of loat

D2: Working height of airbags when loaded
