Under Water Lifting / 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.

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.

Storage of The Airbags

1) If the airbags won’t be used for quite a long time, it shall be washed and dried, filled with talcum powder inside and coated with talcum powder outside, place it in dry, shady and ventilated place in the warehouse.
2) Place string the airbags should be far away from the heat source.
3) The temperature of the warehouse should be kept no more than 30℃.
4) Keep the airbags away from acid, alkali, grease and organic solvent.
5) The airbags should be stretched flat when not used. It is not allowed to pile up and stack heavy object on the airbag.
