Product Introduction:
History of marine rubber airbags.
The airbags is invented in China in about 1986 by some experienced engineers, to help launching small boats in rivers. After years of development of technology, the airbags are adopted to launch huge ship weigh up to 9000 tons or more.
Material: an airbag contains several layers of rubber-dipped Nylon fabric+1 layer of rubber. For example,
7 layers of airbag, means 7 layers of rubber-dipped Nylon fabric + 1 layer of outer rubber.
Every two layers are stick with glue solution and pressed together. The body of airbag is integrate wrapped.
Different layers
The layers varies with the weight and size of ship, as well as the condition of ship launching.
But generally speaking, we will give our suggestion first, and we will produce as the requirement of clients.

As a soft flexible body, airbag’s shape depends on various factors, such as the shape of ship bottom, ramp shape, width of ship bottom, length of airbag, position of airbag under the ship, etc.
Users should calculate the bearing capacity of airbags basing on above factors, correct bearing capacity accordingly.
Caculation of performance of airbags
Formula: Bearing capacity F=PS
P=pressure in the airbag(MPa)
S=contacting area between ship bottom and airbag(M²)
S= π*(D1-D2)/2
Application:
For ship upgrading, conversion or new/repair launching
For hoisting and transporting heavy structures up to 10,000 metric tons
For floating use purpose as improve the draft.
For salvaging sunken ship or heavy immersed steel structure
Culvert making for architecture engineering
