Air Bag
The underwater buoyancy bag, also known as a salvage airbag or underwater air lift bag, is a multi-functional and high-safety industrial-grade auxiliary device. Relying on its unique design and high-quality materials, it is widely used for providing buoyancy assistance in the salvage of underwater sunken objects such as sunken ships, anchor chains, and pipelines. It is applicable in both shallow and deep water environments. Compared with salvage ships, it saves more salvage costs, is flexible to use, has a light self-weight, and is convenient for rapid deployment, transportation, and storage.
Product Advantages
Superior Material: Made of thickened, wear-resistant, and high-strength PVC material, it has excellent tear resistance and anti-aging performance. It can be used stably for a long time under complex working conditions, effectively ensuring operational safety.
Structural Design: The cylindrical inflatable structure is equipped with multiple sets of fluorescent yellow reinforced straps. This not only enhances the overall load-bearing capacity, but also the professional buckles on the straps enable quick connection and fixation, making the operation convenient and efficient.
Diversified Functions: Suitable for scenarios such as equipment hoisting buffering, temporary heavy object transportation, and rescue material transfer. It is a practical tool in the fields of industrial operations and emergency rescue.

Application Scenarios
Underwater Salvage: Cooperates with diving operations to salvage heavy objects such as sunken ships, underwater equipment, and cultural relics. The ascent speed is controlled by adjusting the inflation volume to avoid damage to the salvaged items.
Water Rescue: In water accidents, it provides temporary buoyancy support for trapped people or drowning equipment, assisting rescuers in transferring the targets.
Engineering Assistance: In underwater construction (such as bridge and tunnel construction), it is used for floating large components like pipelines and steel structures, or temporarily fixing the position of underwater equipment.
Leisure Scenarios: Small buoyancy bags can be used as auxiliary equipment for water sports, such as spare buoyancy devices for kayaks and paddleboards, to improve safety.
Usage Precautions
Before use, check whether the material is damaged and whether the inflation valve is sealed to avoid insufficient buoyancy caused by air leakage.
Inflation underwater should be carried out slowly to prevent the salvaged objects or personnel from rising rapidly due to a sudden increase in buoyancy, which may cause safety risks.
The load weight must not exceed the rated floating capacity of the buoyancy bag. It is recommended to reserve a 20%-30% buoyancy margin to cope with additional resistance such as water flow.
For long-term storage, the internal air should be completely released. Fold the buoyancy bag and place it in a dry and ventilated place, avoiding direct sunlight or contact with sharp objects to prevent material aging.
Detailed Highlights
Clear marks are printed on the surface for easy identification and management.
Equipped with an inflation valve, the inflation level can be flexibly adjusted according to needs to adapt to different operational requirements.
Multiple reinforced lifting point designs ensure balanced force during the hoisting process and further improve the safety factor.
Whether it is material transfer in industrial production or material transportation in emergency rescue, this inflatable buoyancy bag can become a capable assistant in your operation process with its reliable performance and convenient operation.
This buoyancy bag is mainly used for the salvage of sunken ships and sunken objects, as well as buoyancy assistance in shallow seas. Meanwhile, it can also be used for the laying of marine cables and pipelines. It is convenient for transportation, simple to operate, and greatly saves manpower and material resources.
