Pioneer and Lear of Marine Airbags in the world--Evergreen Maritime
1 Construction Features of ship launching landing marine airbag:
Ship Launching Landing Airbag, basic body consists of which consist 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 in to roll.
1-1. Outer Rubber
The outer rubber layer that covers the outside of ship launching and landing marine airbag 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.
1-2. Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers of ship launching landing marine airbag, 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.
(To know the detailed technology parameter, please refer Material Selection. )
1-3. End Fittings
End fittings of ship launching landing marine airbag include air tightness swivel and airbags safety air inlet.
2. Classification of ship launching landing marine airbag:
2-1. The standard specification of ship launching landing marine airbag.
You can choose the required diameter and effective length to meet your projects.
L Diameter (D): Its from 0.8m to 2.0m.
L Effective Length (EL): Its from 6m to 18m.
L Total Length (TL): Its from 7m to 19.5m
The above specification only is our standard specification arrange. Other specification ship launching landing marine airbag also can be supplied upon clients request.
2-2. The standard number of layers
We define the number of layer, which means the number of Synthetic-tyre-cord layer, in order to confirm the Safety Working Pressure. Normally, ship launching landing marine airbag
Include 4, 5, 6, 7, 8 layers types. Other type is available upon clients request.
3. The material of ship launching landing marine airbag
There're two kinds of synthetic-tire-cord because of the different performance.
