Flexible Marine Refloat and Salvage Rubber Balloons for Sinked Ships


The other application of rubber marine balloons is marine salvage of sinked vesses underwater by refloating them up. Firstly calculate the necessary buoyance to float a vessel up. Use a number of airbags in suitable sizes, binding them alongside the vessel sides or setting them into the cabinets. Inflate the airbags to displace the water and float the vessel up slowly.

Qingdao Luhang is a leading and professional manufacturer of marine salvage balloonss. They are widely used in salvaging sinked vessels or ships or refloating large and heavy objects from underwater. They are also called salvage air bags, salvage balloons, refloating airbags, refloating air bags or refloating balloons. They will be equipped with bondage belts or cord net around them and fixed around the shipes or heavy objects. After inflation, the salvage airbag has certain buoyance to displace the water and float the sinked vessels up to the water. The selecion of airbags is based on the salvage requirement: the vessel weight, size and how to fix. The airbags can be made maximum to Dia 3m and 24m long.

2. Saving Cost: airbags can be used repeated

3. Heavy Duty: salvage airbags are capable to bear high pressure because they are made of multi-layers reinforced with nylon cords. They can be used more than 10m under water.

4. Equipped with necessories such as inflation pressure gauge, bondage belts, shackles for fixing.



The Construction and Material of Marine Salvage Air Bags                                                               


The airbag wall is constructed with layers of rubbers plates. The inner layers are reinforced with nylon cord net. These layers support the airbag with bearing strength when the airbag is inflated. More layers the airbag wall has, greater strength the airbag has. And the nylon cord net plays a critical role in strength. Besides the cord reinforced layers, there is one extra layer without cord net outside the wall. This rubber layer has a function of anti-wear and anti-aging. To maximize the function of the inner layers and the exterior layer, the rubber material is specially optimized with suitable mixing formulas.
