Introduction and Achievement
Evergreen is the inventor of first marine balloon for boat ,ship,vessel,yacht, and sets the standard in the industry for high performance and usage technology. Now, Evergreen marine balloon for boat ,ship,vessel,yacht, are widely used in ship launching and landing, sunken ships salvage and refloatation, heavy lifting and conveying.
Construction Features of marine balloon for boat ,ship,vessel,yacht:
marine balloon for boat ,ship,vessel,yacht, 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. Outer Rubber
The outer rubber layer that covers the outside of marine ballon for boat ,ship,vessel,yacht, protect 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.
2. Synthetic-tyre-cord layer for reinforcement
The reinforcement cord layers of marine balloon for boat ,ship,vessel,yacht, 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. )
3. End Fittings
End fittings of marine balloon for boat ,ship,vessel,yacht, include air tightness swivel and airbags safety air inlet.
Classification of marine balloon for boat ,ship,vessel,yacht:
1. The standard specification of marine balloon for boat ,ship,vessel,yacht.
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 rubber balloon, also can be supplied upon clients request.
2. The standard number of layers of marine balloon for boat ,ship,vessel,yacht
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 Airbag Include 4, 5, 6, 7, 8 layers types. Other type is available upon clients request.
3. The material of marine balloon for boat ,ship,vessel,yacht,
There're two kinds of synthetic-tire-cord because of the different performance.
Rubber balloon Unit 1400 dtex/21870 dtex/2
Break Strength N/ strand ≥ 215.6 ≥ 284.2
Diameter mm 0.65 ± 0.05 0.74 ± 0, 05
Adhesion Strength N/cm ≤ 137.2 ≤ 156.8
4. Our marine balloon for boat ,ship,vessel,yacht, is also known as:
marine balloon for boat ,ship,vessel,yacht for upgrading and conveying
marine balloon for boat ,ship,vessel,yacht for hoisting and transporting heavy structure
marine balloon for boat ,ship,vessel,yacht for refloatation, salvaging sunken ship or heavy immersed steelstructure
marine balloon for boat ,ship,vessel,yacht for erecting floating bridge or pipeline
