ISO Certificate Marine Salvage Airbag Salvage High Quality Ship Launching Marine Salvage Airbag For Sale
Overview of ship salvage airbag
Vessel salvage airbags are also called rubber rollers, marine lifting rubber tubes. They are widely used for salvage engineering and floating operation. They are the best choice for 100-2000 tons buoyancy needs. Florescence airbags have the advantages as below:
1. Special synthetic tyre cord layer material
Our salvage airbags are made of special synthetic tire-cord layers, which have much better performance than PVC coated fabrics.
2. High pressure design
The maximum working pressure for lifting the airbag is 0.25 Mpa. This means that they can be used at a depth of 25m.
3. Holistic screw type salvage airbags
Our rubber rollers are a totally enclosed tube with cone ends. It is manufactured using holistic screw technology. This design ensures that there aren't any welded seams. This makes them stronger than RF welded salvage airbags.
4. Equipped with accessories
Salvage lifting rubber bags are equipped with rubber handles, nylon rope net and pulling rings.
Working principle of rubber airbag
Through inflating the compressed air to produce buoyancy, then using buoyancy to salvage. It is easy to operate and safe and reliable.
In addition to hang a ship in a fixed position or connected with lifting jack of the bottom of ship, ship airbag also can be placed inside the ship cabin, through filling out the cabin water to provide buoyancy.
How to salvage a ship?
What equipment need to install / fix / inflate the airbag for salvage?
You will need the diver to dive underwater and strap our deflated airbag to the bottom or side of the rescue boat with a rope or net. Then the airbag is inflated with an air compressor connected through a rubber hose on the ground.
In addition to airbags, we can also provide any equipment required during the lifting or salvage of the ship, including ropes or nets, winches, rubber tubes and air compressor machines.

Production line of ship airbag
Technology of our floating rubber airbag is overall winding.
The overall structure is more reasonable, the texture is clear, there are no juncture, high load. It is safer than the overlap technology (roller), and the bearing capacity is stronger.
