Marine Rubber Airbags
Through listening to our customers, DOOWIN develop the heavy-duty marine rubber airbags, which are the toughest marine salvage airbags.
DOOWIN marine airbags are the system of choice for reliable, controllable buoyancy . They are well-work for installation buoyancy on pipeline float-out, beach pulls and river crossings. In addition, our rubber ship launching airbags have applications such as vessel and platform draught reduction in limited water depths.It could also use as salvage pontoons for temporary bridges and docks. The people can use rubber airbags to salvage the shipwreck, rescue the floating bridge and dock construction.
It really comes into own when rubber marine salvage airbags employed in heavy-duty salvage work under severe environment.
DOOWIN marine rubber air bag is enclosed cylindrical shape buoyancy units. We construct the rubber airbags with high tensile out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly.
Marine airbags for ship launching are cylindrical balloon body, with two conical head and end mouth, fitted with air tightness swivel and air inlet kits at end mouth. Polyester webbing lifting straps are around the whole rubber airbag body. The total lifting of these straps maintains a minimum 6:1 safety factor of its buoyancy. Can equip the auto pressure to relieve valves, which can open when inner pressure reaches rated pressure.
Marine Rubber Airbags Specifications
Different combination of diameter and length, make rubber marine airbags achieve different buoyancy capacity.
Features and Advantages
All DOOWIN marine airbags are manufactured and tested comply with ISO 14409 “Ships and marine technology – ship launching air bags” and IMCA D016 Underwater Air Lifting Bags, certificated by third party classification society.
- Super-high Tensile Strength — Heavy-duty synthetic-tire-cord layers is framework material of our marine rubber air salvage bags. It can bear super high working pressure, even for the deep water from the surface operation.
- Resistant to Abrasion — The thickness of DOOWIN marine rubber air lift bags is up to 12mm or more. So it can resistant the scratch and abrasion under severe environment. Even damage the out rubber layer. The inner synthetic-tire-cord layer also can work well.
- Multiple Applications — Can use marine rubber lift bags for the surface buoyancy support same with enclosed air lifting bags. Also can use it for the salvage work from deep water to the water surface.
