      Underwater Cylindrical Air Lifting Bags

       

      Manufactured Underwater Cylindrical Air Lifting Bags in India

       

      Underwater Cylindrical Lift Bag is a type of underwater air lifting unit in the shape of a cylinder with a single lifting point also known as Surface–Buoyancy-Lift Air Bag. The purpose of any underwater lift bag is to salvage drowned objects from rivers/oceans.

      These air lift bags are enclosed, pontoon style ideal for shallow water operations. Usually, due to the enormous costs involved with salvaging, drowned objects like vessels, marine structures, dam gates, etc. are left underwater and now with the help of these bags, it’s easy to take them to the surface.

      These bags are associated with a spring-loaded dump valve mounted in the center of the top lift plate for excess pressure relief. Welded seams make them strong and durable. They are common use for commercial and military salvage operations to lift objects from shallow water depths. Therefore, air lift bags serve all-purpose, especially cable and pipeline operations, marine salvaging, lift bag salvaging, etc. We manufactured & supply of premium quality underwater air lifting bags in India.
