Wrech Salvage Refloating Natural Rubber Marine Salvage Airbags

Product Introduction:

The marine salvage airbag is a buoyancy assist airbag made by Qingdao Shunhang Marine Supplies Co., Ltd. according to the demand characteristics of the salvage project. Underwater salvage projects generally have the characteristics of complicated operations, high costs, and strict requirements on equipment and personnel. How can salvage projects save time and effort? Shunhang marine supplies technicians designed this inflatable float-assisting and salvaging airbag after dedicated research.

Inflatable buoyancy and salvage airbags have the advantages of light weight, strong air retention performance, deep water pressure resistance and convenient carrying. Therefore, it is widely used in salvage projects such as sunken ship salvage, stranded ship, pontoon bridge, caisson, etc.

The conventional diameter of the airbag can be 0.5m-2.5m, the length can be 5-28m, and the number of layers can be 4-12. Other models can also be produced according to customer needs. The structure of the airbag is composed of the airbag body and the end iron parts. The bladder wall is made of natural rubber and nylon cord fabric through vulcanization; the end iron piece is made of metal material, and the surrounding is tightly combined with the bladder. Each air bag is equipped with a set of inflation valve, pressure gauge, wire connection, tendon pad, wire loop, and wire mouth.

The airbags are applied in ship launching project, also in ship landing, moving, salvage for stranding, etc.

Basing on the traditional products , combine years of technology and experience, we developed the anti-explosion ,integrate wrapped airbags.
Our airbags is different from the airbags from other competitors, One of the most features that make us different is the air tightness.

In addition, we have strict quality control system, every layer is sticked, pressed and stamped again and again, make sure there is no space and air between every two layers. That is why there is no swell on the surface of our airbags.
We have established long-term cooperation with some of the leading shipyards in China, and Malaysia, Indonesia, Singapore,Philippines, further more, we are working to expand our business in Europe, America, Russia, Australia.
We will follow the policy” Innovation in technology, quality strictly controlled, delivery in time”, cordially expect long-term cooperation with every client.

Features of Marine Salvage Airbags

Feature of Shunhang Products:

1. Big carrying capacity

The carrying capacity of the inflating marine rubber airbag is an important indicator of its quality. The CB/T 37951996, The Airbag For The Ships Up To Slipway And Launching, specifies its working pressure and the load-bearing capacities per meter under various compression ratio. Our new generation of airbags are made of novel rubber compounding and high-tension fortifying fiber. Their carrying capacities have been over one times stronger than the standard requirements. That means that less airbags are needed for the ships up to the slipway and launching if with Shun hang marine rubber airbags meanwhile the safe reliability is also guaranteed.

2. High capacity against compression and twisting

When the airbag moves under the ship bottom, it will be compressed between the ship bottom and the ground. As the rolling velocities are not the same among them, they would be torsional deformed. This composite deformation created by both the compression and twisting is described as compressed and twisted movement. When such compression and twisting happens on the air bag, its partial wall would buckle. Then the wall in structure of the multi-layer fortifying fibers would very easily laminate and tear out, resulting the breaking of the fortifying fiber and consequentially the bursting of the entire airbag.

3. New design of anti-bursting construction at the end

For our new generation of airbags, both the rubber compounding and making process are improved so that their structural tearing strengths are improved and so for their capacity for twisting and compression resistance. The deflating possibility would increase at the joint of the end ironwork and the rubber as the working pressure rises.Once it leaks at the end after repeated operation, the end would be more likely to burst out under the high pressure and injure the people.Such accidents due to poor air bag quality have happened many times in the ship launching. We should keep alert on it. To meet the requirement on the air tightness under high internal pressure, the new anti-blasting construction is designed with the end to enhance the binding strength and air tightness at the joint of the bag body and end ironwork. This design could meet the increased working pressure and has been free of the leakage so far in use and proved safe.
