Marine rubber airbags is a marine airbag with inflated air manufactured by rubber used for new-constructed ships’ and marine launching, salvage, heavy lifting, rescue for sunken ships. Inflatable marine rubber airbags for launching is the marine use of pneumaticed rubber marine airbags. China is the Origin of marine rubber airbag with independent intellectual property right. Due to custom varieties from countries to countries, marine airbags are sometimes named marine airbags for ship launching, roller bags, ship launching balloon directly as well as inflatable marine airbags.

Marine rubber airbags for launching
Since rubber marine airbags are made of raw rubber and other materials, owning higher tensile strength and better tearing strength, are widely being used for shipbuildings repair companies and construction field. Marine airbags can lift vessels and boost ship launch together rolling while inflated. Marine rubber airbags can be applied to vessels up to 80,000 Tons. Referring to ship launching,marine rubber airbags are called rubber balloon, inflatable pneumatic rollers, roller bags, launch rollers. It is a most welcomed launching technology nowdays besides floating dock and dry shipway by ship owners due to their good safety, less labor and time cost. Marine rubber airbags break the restriction of lauch ships with slipways, attracting a bigger part of marine business for some shipyards.
Rubber marine airbags for salvage refloation
During launching of ships with marine rubber airbags, there are some stranded vessels needed to be rescued, ship launching marine airbags are employed to complete this job due to their superior flexibilities in water. Naturally, marine airbags are called salvage airbags while performing rescue works. This kind of buoyancy airbags are designed with lifting belts directly, equipped withstanding pressure gauages. Marine rubber airbags can be placed underwater for salvage and refloation. They are applied to caissions and concrete etc.
Rubber marine airbags for pipeline plugging
Small inflatable marine rubber airbags can be used for pipeline plugs sealing in construction field.
Marine rubber airbags specification
> Ship launching marine rubber airbags’ Diameter:
According to ISO 14409, there are typically 0.8 m, 1.0 m, 1.2 m, 1.5 m, 1.8 m, five standarded sizes, now, we extend another eight sizes which are 0.6 m, 0.7 m, 1.4 m, 2.0 m, 2.5 m, 3.0 m, 3.5 m, 4.0 m.
> Marine airbags EL: ranged from 6 m to 24 m
> Inflatable airbags Layers: from 5 layers to 10 layers or more.
> Rubber airbags two Ends: including air inlet swivel, air tightness swivel, all hot dipped galvanized, available steel stainless
Marine rubber airbags construction
As origin of inflatable ship launching marine rubber airbags, we have been taking traditional holistic enlacing technology to produce launching rubber air balloons. Our rubber marine airbags for ship launching is consisted of inner rubber layers, middle reinforced layers and outer rubber layers.
Inner rubber layers
Meeting standard of ISO 14409, our rubber layers have qualified tensile and tear strength in below sheet.
Rbber dipped synthetic tire cords layers
As middle layers of ship launching marine airbags, rubber dipped synthetic tire cord layers are twined at at certain angle to strength the capacities of an marine airbag.
outer rubber layers
Sames as inner rubber layers
Marine rubber airbags performance table
During works of marine rubber airbags such as launching, dry docking, working height of marine airbags are adjustable, however, different working heights of one marine airbags perform different capacities. find more details in below sheet.
