Through listening to our customers, DOOWIN has develop the heavy duty marine rubber airbags (MRA), which are the toughest inflatable buoyancy airbags.
DOOWIN marine rubber buoyancy airbags are the system of choice where reliable, controllable buoyancy is required. They are particularly suited for installation buoyancy on pipeline float-out, beach pulls and river crossings. Our marine rubber airbags have also been used in applications such as vessel and platform draught reduction in limited water depths, and as salvage pontoons for temporary bridges and docks. MRA also can be used to salvage the shipwreck, rescue the floating bridge and dock construction.
It really comes into own when marine salvage airbags employed in heavy-duty salvage work under severe environment.
DOOWIN marine rubber airbag is enclosed cylindrical shape buoyancy units. Constructed from high tensile out rubber layer, multilayer heavy-duty synthetic-tire-cord layers, and an inner rubber layer vulcanized firmly.
Marine rubber airbags 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 is round the whole marine rubber airbag body. The total lifting of these straps maintain a minimum 6:1 safety factor of its buoyancy. Can equip the auto pressure relieve valves, which can open when inner pressure reach rated pressure.
Features and Advantages of Marine Rubber Airbags
Super-high Tensile Strength — Heavy-duty synthetic-tire-cord layers is framework material of our marine rubber airbags. 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 airbags is up to 12mm or more. So it can resistant the scratch and abrasion under severe environment. Even the out rubber layer was damaged. The inner synthetic-tire-cord layer also can work well.
Multiple Applications — Marine rubber airbags can be used for the surface buoyancy support same with enclosed air lifting bags. Also can be used for the salvage work from deep water to the water surface.
Marine Rubber Airbags Buoyancy
Different combination of diameter and length, make marine rubber airbags achieve different buoyancy capacity.
Note: Other size can be provided upon request.
All DOOWIN marine rubber 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.
