1.5m Inflatable Marine Salvage Bag High Buoyancy Quick Seal Valves
ISO Certified
Description
Engineered for mission-critical reliability, Inflatable Salvage
Tubes meet the demanding requirements of military and heavy
industrial salvage. Built with military-grade materials for extreme
durability, pressure resistance (300m+), and resistance to
corrosion, fuel, and abrasion, they perform reliably in hostile
environments. Redundant air chambers and automatic pressure relief
ensure fail-safe buoyancy even if compromised. Their rapid
inflation capability is vital for strategic asset recovery or
urgent operations. Compatible with ROVs for covert deployment, they
facilitate the recovery of submarines, sensitive equipment, or
large infrastructure like pipelines and offshore platforms. This
robust, secure technology provides unmatched lifting power where
failure is not an option.

Features
Pressure Resistant Structure
Features reinforced seams and internal pressure-balancing valves to
prevent over-expansion or collapse under varying water pressures.
Integrated Smart Monitoring
Embedded pressure sensors and GPS transponders provide real-time
buoyancy and location tracking for precision control.
Corrosion Chemical Resistance
Specialized coatings protect against saltwater corrosion, oil, and
chemical exposure, ensuring long-term usability in marine
environments.
Customizable Sizes (0.5m – 5m Diameter)
Available in various diameters to match specific salvage needs,
from small aircraft parts to large submerged structures.
Applications
● Damaged submarine cable recovery
