Durable Marine Lifting Balloons Synthetic Cord Rubber High Load Capacity
Durable Marine Lifting Balloons Synthetic Cord Rubber High Load Capacity
Description
Manufactured by Hongruntong Marine, our Marine Salvage Airbags feature a seamless, cylindrical design optimized for controlled underwater lifting and refloating. Each airbag undergoes strict quality inspections and pressure tests to ensure safe use in demanding marine conditions.
Constructed with high-tensile strength cord and wear-resistant rubber layers, these airbags maintain stability under high loads and repeated usage. Ideal for ship launching, wreck recovery, or underwater buoyancy support, they deliver consistent performance and minimal maintenance downtime.

FAQ
1. How are the airbags used in salvage operations?
They are positioned beneath or around sunken objects, inflated to generate buoyant force, and gradually lift the load to the surface.
2. Can the airbags be reused?
Yes, they are designed for multiple uses under proper operation and maintenance.
3. Are the airbags suitable for deep water use?
Yes, depending on the pressure rating and design, they can be used at depths up to 50 meters or more.
4. What safety features do they have?
Each airbag includes overpressure relief valves and is hydrostatically tested to prevent bursting and ensure safe lifting.
