Heavy Duty Inflatable Rubber Airbag

Heavy Duty Inflatable Rubber Airbag 

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.

While inflated, marine rubber airbags can lift ships and heavy objects like for movement. Their heavy duty strength guaranteed marine rubber airbags could not be the best solutions.

Features : 

1. Our rubber airbags make with 3-strand cords .

2. High quality natural rubber raw material  .

3. Superb quality and above average thickness for rubber layers .

4. Strictly comply to the standard of ISO 14409:2001 (E) Ships and marine technology – Ship launching air bags.

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.
