Reinforced Salvage Air Bags For Ship Recoery 6 Layer Construction
Wear Resistant
Description
Hongruntong Marine’s cylindrical salvage airbags are designed for
versatile marine applications, offering unmatched flexibility and
lifting strength. With diameters ranging from 0.8m to 2.5m, these
airbags can lift heavy underwater objects up to hundreds of tons
with precision and safety.
Our airbags are fabricated using vulcanized rubber and synthetic
layers for enhanced pressure retention, corrosion resistance, and
thermal stability. Widely trusted by shipyards and offshore
contractors, they are lightweight, portable, and easy to deploy in
tight underwater spaces.

FAQ
1. How are the airbags inflated and deflated?
Using standard air compressors or scuba tanks via quick-connect
inflation valves and deflation outlets.
2. Do you offer custom designs?
Yes, we can customize size, lifting capacity, fittings, and
accessories to meet your project requirements.
3. How should the airbags be stored?
Store in a dry, shaded area away from direct sunlight and
chemicals. They should be fully deflated, cleaned, and rolled.
4. Can the airbags be used in rough seas?
Yes, but care must be taken during inflation and lifting to ensure
control and stability, especially in dynamic conditions.
