Standed Vessels Rescue Floating Marine Salvage Airbag
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.
Features of Marine Salvage Airbags
Not easy to be affected to wind and wave.
Less demand of binding.
Easy to meet the needs of buoyancy ranging from 100 tons to 2000
tons.
Easy to transport and store while the airbags are deflated.
Super-high tensile strength owing to its framework material -
heavy-duty synthetic-tire-cord layers with breaking strength about
more than 15,000 N/ 5cm.
Excellent resistance against abrasion and scratch.
Low maintenance.
High flexibility and cost effectiveness.

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.
Attention During Application
1. Working pressure must be controlled strictly, it is not allowed
to exceed the working pressure.
2. No sharp and protruding hard object on the contacting surface of
the airbags, to avoid the puncture on the skin of airbags.
3. Avoid the distortion along the length of airbag.
4. Empty inflating test must be performed if the airbags were not
used for a long time or after reparation. The pressure should be as
same as the testing pressure of our company. Inspectors must be at
least 3 meters away from the airbags. For repaired airbag which was
damaged in large scale, its working pressure should be lowered
reasonably. Besides, annual check should be conducted on airbags
which are used frequently.
5. Don’t drag the airbags on the ground.
