China Marine Salvage Underwater Air Lift Bag

Marine Salvage Underwater Air Lift Bags     Marine salvage underwater air lift bag  description:   Marine salvage underwater air lift bags include the open bottom parachute type air lift bags, totally enclosed type air lift bags, pillow type air lift bags, inflatable buoyancy bags, pipeline buoyancy system.   Marine salvage underwater air lift bag are used world-wide for raising sunken objects, vessel salvage, marine structure stabilization, underwater equipment transport, pipeline and equipment towing, and standby emergency buoyancy.   All marine salvage underwater air lift bag  are manufactured comply with IMCA D016 Guidlines.       Marine salvage underwater air lift bag type:   --Open bottom  marine salvage underwater air lift bag: DooFlex open bottom Marine salvage underwater air lift bag is designed with water drop shaped units, which is widely used for buoyancy support, marine salvage airbags, or lifting sunken objects operation of underwater diving work. open bottom  design make the operation more safety.  open bottom  Marine salvage underwater air lift bag is one kind of very useful floataion device for the diving salvage, underwater salvage, and underwater buoyancy support and refloatation.               --Totally enclosed   marine salvage underwater air lift bag:   DooFlex totally enclosed type marine salvage underwater air lift bag (salvage tube, inflatable buoyancy bags) is one kind effective alternative  for the surface buoyancy support operation. 
Totally enclosed  Marine salvage underwater air lift bag can be used for buoyancy support and refloatation operation in shallow water and on the surface, support/salvage pontoons for bridges, floating platforms, dock gates,  sunkend objects or military equipment. Totally enclosed Marine salvage underwater air lift bag
 offer an effectual method of reducing the draught of vessel and floating underwater structures. Then also provide an ideal system of buoyancy for cable and static buoyancy support.              Marine salvage underwater air lift bag features and advantage:   -    Made of heavy duty PVC coated polyester fabric
