Buoyancy Bags Custom Inflatable PVC Marine Salvage Cylinder Buoyancy Airbags
Description
The principle of buoyancy plays a central role in the design of Buoyancy Bags. These bags utilize Archimedes' Principle, which states that an object submerged in fluid experiences an upward force equal to the weight of the displaced fluid. By inflating the buoyancy bag with air, the bag displaces water, creating an upward lifting force. Buoyancy Bags are carefully engineered to ensure they provide the right balance of buoyancy relative to the weight of the object being lifted, making them a reliable tool for underwater lifting operations.
