Underwater Air Lift bags are manufactured comply with IMCA D016 Guidelines.
Heavy Duty Air Inflated underwater air lift bags products are used world-wide for raising sunken objects, vessel salvage, marine structure stabilization, underwater equipment transport, pipeline and equipment towing, and standby emergency buoyancy.
Open Bottom Parachute Type Air Lift Bags is designed with water drop shaped units, which is widely used for buoyancy support or lifting sunken objects operation of underwater diving work. The open bottom design make the operation more safety. It's one kind of very useful floataion device for the diving salvage, underwater salvage, and underwater buoyancy support and refloatation.
Open Bottom Parachute type lifting bags are fabricated from heavy duty polyester cloth coated with PVC made in German. It has safe working load of 6:1. Each Open Bottom Air Lift Bag is equipped with manual air dump relief/dump valve, which can be controlled easily to change the buoyancy by the bottom rope. And certificated heavy duty polyester webbing with end shackles, and air inlet stainless/ brass ball valves are equipped for the lifting operation. Each parachute lifting bag is complete and ready for use when leaving our manufacturing facility.
Totally Enclosed Air Lift Bags can be used for buoyancy support and re-flotation operation in shallow water and on the surface, support/salvage pontoons for bridges, floating platforms, dock gates, sunk end objects or military equipment. Totally enclosed lifting bags offer an effectual method of reducing the drought of vessel and floating underwater structures. Then also provide an ideal system of buoyancy or cable and static buoyancy support.
Headway Totally Enclosed Type lifting bags are cylindrical shaped units, fabricated from heavy duty polyester cloth coated with P.V.C (Made in Germany), completely equipped including the appropriate quantity of automatic air relief valves, certified heavy duty polyester webbing with shackles (with safe working factor 6:1), and air inlet stainless/brass ball valves.
Enclosed Pillow Air Lift Bags are one kind versatile lift bags with totally enclosed pillow type. It can be used in shallow water with the maximum lift capacity for the refloatation work and towing jobs.
Enclosed pillow type air lift bags are manufactured from high-strength PVC coating fabric, which is highly abrasion, and UV resistant. Each enclosed pillow air lift bags are equipped with heavy duty webbing harness with single pick points and screw pin shackle, over-pressure valves, stainless steel ball valves and quick disconnects. Custom sizes, and rigging options are available upon request.
Elongated Inflatable Buoyancy Bags / Pontoon (Salvage Tube) are versatile in multiple application.
The main application is to raise the sunken boat from deep water, shipwreck salvage, re-flotation as re-flotation/ salvage air bags. Meanwhile, they can be used as salvage tube/ salvage pontoons for the supporting docks and other floating structures, and they also excellent for the pipe-laying and other underwater construction projects.
Elongated Inflatable Buoyancy Bags/Pontoon air lift bags (Salvage Tubes) are manufacturer using highly quality PVC coating fabric made in German. It also is equipped with heavy duty webbing harness with single pick points and screw pin shackle, over-pressure valves, stainless steel ball valves and quick disconnects. Custom sizes, and rigging options are available upon request.
Individual pipeline buoyancy bags are designed to provide buoyancy continually, to support the submarine cable or steel pipe during installation and transportation in shallow water
Individual Pipelaying Buoyancy Bags
Individual Buoyancy Bags for PipelineThe individual pipelaying buoyancy bags are manufactured using the high quality material PVC coated fabric which has highly abrasion resistance, and UV resistant. The arrange of size is various. It can made into any diameter and length upon the special requirements for the projects.
The using method is very flexible and various. One way, the pipeline float are supplied in flat form. When deploy the pipeline, the pipeline float can be attached to the pipeline at 1m spacing continuous. When deploy the correct length of cable to the suitable position, then open the end valves and deflate the air, let the pipeline sink into the water. It’ll get the better buoyancy performance when the total enclosed type air bags are used at the same time.
