The elongated float bags are enclosed, elongated cylinders with a main capacity of 500kg to 5,000kg. It is the salvage tube of choice when shallow water is a critical factor and towing is a concern.
Lifting points are equally spaced along the length of the salvage tube. Float bags salvage is the main application. The float bags also can be used as salvage tube, salvage pontoon for the supporting docks and other floating structures. And, they are also excellent for the pipe laying and other underwater construction projects. DOOWIN elongated float bags salvage tube are manufactured using high-quality PVC coating fabric. We equip each float bags with heavy duty webbing harness, and screw pin shackles, over-pressure valves, stainless steel valves, and quick disconnects. Customized size and rigging options are available upon request.
Made of heavy-duty PVC-coated polyester fabric certificated by SGS.
Relief valves can open automatically to release inside pressure to prevent burst.
Design safety working factor 5:1 at least complying with IMCA D016.
Small diameter with elongated body design used for shallow water is a critical factor.
DOOWIN elongated pontoon lift bags are from 500kg to 5,000kg. The below specification is the common size. We also make other size and capacity float bags salvage tube upon request. Custom sizes and rigging options are available upon request.

Air lift bags exhibit remarkable adaptability, making them perfect for secure buoyancy support and lifting heavy objects regardless of water depth.
Inflatable buoyancy units can be used for surface marine salvage, pipelaying buoyancy floats, and vessel draught reduction.
Pillow-shaped enclosed flotation bags can float objects in extremely shallow water, utilizing upright or flat, outside or inside of structures.
Mono buoyancy units enable efficient pipeline/surface operations with time-saving single-point connections and wide-angle adaptability.
DOOWIN specializes in manufacturing high-performance underwater air buoyancy bags designed for marine salvage, buoyancy assistance, and emergency rescue operations. Crafted from durable, high-strength materials, our bags are engineered to withstand extreme underwater pressures and harsh environments. Available in multiple sizes and load capacities, they offer versatile solutions for lifting sunken objects, stabilizing submerged structures, or providing critical flotation support during rescue missions.
Thank you for the opportunity to serve you.
