Marine Rubber Ship Airbag for ship launching:
High strength ,high quality
natural rubber,anti-aging
good air tightness

The above specification only is our standard specification arrange. Other specification of ship launching airbags also available upon clients’ request.

Standard number of plies (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, Evergreen Airbags include 4, 5, 6, 7, 8 layers types. Other types is available upon clients request.

Synthetic-tire-cord of Evergreen Marine Airbags

There’re two kinds of synthetic-tire-cord because of the different performance

Principle for marine airbag selection
In fact it is easy to choose suitable airbags by yourself



Standard specifications of Evergreen Ship Launching Airbags  
Diameter (D)          : From 0.8m to 2.0m.
Effective Length (EL) : From 6m to 18m.
Total Length (TL)     : From 7m to 19.5m

Marine ship rubber airbags are for ship

1 High strength ,high quality
2 natural rubber,anti-aging
3 Good air tightness

ship airbag for launching

marine airbags used for launching
Select the airbag’s effective length not less than the maximum width of vessel or anything you want to move by airbags. But when you arrange two rows of airbags keep in mind to calculate the total length to avoid contact of airbags in two rows. The total length of airbags can be estimated to be effective length plus diamter. It says an airbag whose effective length is 16 meters and diameter is 1.5 m then its total length is 17.5 m.

heavy lifting rubber airbag
Diameter of airbag is decided by the height of your vessel’s support blocks. If the support block is 1 m high, then you should choose airbag’s diamter not less than 1.5 m. If you get 1.5 m high blocks, the airbag with 2m diameters will suits you well.
For air lift use, airbag’s diameter or length is mainly decided by the buoyancy you need from airbag. And also consider the pressure of airbag stands if you apply airbags in deep water.
Foe caisson transport by marine airbags, the most suitable diameter is 0.8-1 m.

Marine airbag’s performance is decided by its component plies. For air lift use or light vessel (launch weight below 2000 tons) launch,mid-pressure airbags are enough. For heavy duty work, the high pressure airbag should be selected. Generally speaking, airbags with 6 plies are enough for most engineering works. Only in some rigorous situation, airbags will need 7-8 plies to enhance its performance. For example, if peole use airbags to lift heavy caisson but their contact area is limited, then airbags will need higher pressure and more plies to ensure the safety.
