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.
