Marine Salvage Rubber Airbags

Marine salvage rubber airbags are evolved from ship launching rubber airbags. All manufacturer produce the rubber marine salvage airbags using heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape. In the beginning, people used these rubber airbags to launch a ship or lifting heavy objects. And, then people started to equip the lifting belts with rubber airbags as marine salvage airbags.

The rubber marine salvage airbags are cylindrical balloon body with two conical head. There are air tightness swivels and air inlets at end mouth. Polyester webbing lifting straps are around the whole marine rubber airbags.

Relative merits of marine salvage airbags

Its material is synthetic-tire-cord layers that covered with high tensile rubber layers. Its thickness is up to 12mm or more. So it can resistant the scratch and abrasion under severe environment. It is the most outstanding advantages than the PVC made marine salvage airbags.

But these marine salvage airbags are too heavy. Per square material is about 1.8kg. For example, one 1.5m diameter x 10m length 6 layers rubber airbags. Its buoyancy capacity is about 17ton. But its weight reaches 400kg. Per 17ton enclosed lifting bags is only about 120kg. So, its outstanding disadvantage is too heavy. Not suitable for the small vessel salvage.

Application of rubber marine salvage airbags

Marine rubber salvage 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. We can use the marine rubber airbags in applications such as vessel and platform draught reduction in limited water depths. And, some users also use it as salvage pontoons for temporary bridges and docks. In addition, also can it for salvage the shipwreck, rescue the floating bridge and dock construction using these airbags.

When rubber marine salvage airbags employed in heavy-duty salvage work under severe environment. It comes into its own.
