Product Description
Product Description
Ship launching airbags, known as roller bags or ship launching balloons, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape. Ship launching airbags can be used for ship launching, ship landing work.
Ship launching or upgrading using marine airbags is an innovative ship launching technology. It overcomes the disadvantage of "end-on launching", "side ship launching", "float-out". This ship launching technology overcomes the restrictions of the fixed launching track of side-launch.
The application of marine launching airbags is less subject to site restrictions and does not require large-scale mechanical equipment, so it can shorten the project cycle and save a lot of money. This product has the characteristics of safety, efficiency, green environmental protection, mobility and flexibility. It has been widely used in lifting and moving heavy objects, launching and launching ships, lifting and moving caissons, handling of other heavy objects, and assisting in underwater installation projects. Floating areas.
This flexible ship launching technology is accepted by more shipyards worldwide because of its advantages of saving time, saving investment, flexibility, safety. We are constantly innovating in terms of design, material usage, & manufacturing technologies throughout the years to ensure flexibility, safety, and reliability.The production process of the new high-strength airbags of China National Aviation Corporation adopts the most advanced technical standards;The company has complete inspection equipment to ensure that raw materials,semi finished products,and finished products pass the customs.The airbag has a large bearing capacity,good air tightness,long service life,and is safe and reliable,and is highly welcomed by the majority of users.
Up to now, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks have all been launched using our rubber airbags. The biggest vessel launched by ship launching airbags up to 100,000DWT.
Our ship launching airbag is the No.1 choice by companies in Southeast Asia, Europe, Turkey, Middle-East, North America, Africa, South America.
Production structure
2.1Outside the rubber cover outside the spacecraft launching airbag external rubber layer can protect the rope from the effects of wear and other external forces. This compound has sufficient tensile and tear strength to withstand any weather conditions and hard use.
2.2 used for reinforcement of composite tyre cord layer reinforced by tyre cord layer of commonly used synthetic tyre cord and rubber modified, arrange cord Angle of ideal, to maintain the internal pressure and uneven distribution of stress and provide powerful effective reinforcement. The airbags launched by AVIC ships adopt two types of synthetic tire cord to achieve the best performance.
2.3 in direct contact with the innermost rubber inflatable rubber gas, its core function is to ensure that the air tightness, prevent gas leakage. At the same time, it needs to withstand the huge internal pressure, adapt to the deformation of the airbag caused by operations such as launching the ship, and evenly disperse the stress.
2.4 End Structure
End Reinforcement Ring: Steel or high-strength composite material rings are built into both ends of the airbag to secure the cables or connect multiple airbags and prevent end deformation.
Flange Interface: Equipped with standardized inflation valves (such as quick couplings) for easy connection to high-pressure air pumps.
2.5 Safety Devices
Overpressure Safety Valve: Automatically releases pressure when the internal pressure exceeds the design value to prevent rupture.
Pressure Monitoring Interface: Can be connected to external pressure gauges or sensors to monitor the inflation status in real time.
a.Standard specifications of Ship Launching Airbags
b.Diameter(D): From 0.8m to 2.0 m.
c.Effective Length (EL): From 6m to 22 m.
d.Total Length (TL): From 7m to 24 m
e.The above specification only is our standard specification arrange. Other specifications of ship launching airbags are also available upon clients' request.
We define the number of layer, which means the number of Syntheic-tyre-cord layers, in order to confirm the Safety Working Pressure. Normally, Zhonghaihang Airbags include 4, 5, 6, 7, 8 layers types. Other types is available upon clients request.

Production and installation
Applicability of airbag
The airbag launching feasibility of a specified vessel should be calculated first but there are some simple rules may help people to know launch feasibility quickly.
The majority of airbag ship launching is end launching but side launching is feasible only when some rigorous conditions are satisfied.
Vessels whose DWT below 70,000 tonnes may be launched with aibags. Regarding bigger vessels only by calculation people can know the launch feasibility.
Other applications of airbags
7.1 Hoist and handling airbags: They can be widely used for handling the various large prefabricated reinforced-concrete products( such as caisson, box culvert, bridge), oil drilling equipment and integrated building, etc.
7.2 Floating and filling airbags: The corresponding buoyancy can be offered on the client's request during wreck salvage and underwater installation operation. Filling and floating gasbags can be flexibly combined for wreck salvage, pontoon bridge installation, dock, above water transmission pipeline, etc. in many ways such as cabin occupation , etc.
7.3 Water supply and drain airbag for ship: It is widely used for water supply and drain engineering for large-size, medium-size and small -size ships, with labour-saving, time-saving and physical force -saving.
7.4 Mandrel airbag: It can substitute for the wooden or steel mandrel used for pouring hollow large reinforced concrete structure.
7.5 Container airbag: It can be used as the gas or liquid storage and transport container.
Airbags points for attention
8.1.When the air bag is not used for a long time, it should be washed and dried, filled inside and coated with talc outside, and placed indoors in a dry, cool and ventilated place.
8.2.The airbag should be stretched out and laid flat, and should not be stacked, nor should heavy weights be piled on the airbag.
8.3.The air bag should be stored away from heat sources.
8.4.The air bag should not be in contact with acids, alkalis, fats and organic solvents.
