Large Ship Launching Balloon Air Lift Marine Rubber Airbag Inflatable

Laxury Large Ship Ballon Launching Inflatable Air Lift Marine Rubber Airbag

Florescence ship rubber airbag comply with ISO 14409. ship airbag can be used to launch and upgrade a ship up to 100,000DWT. Comparing to the traditional slipway launching method, the ship launching airbags are much environmental, because ship airbag can launch a ship at any seaside, so there's no need to worry about the construction of launching facilities; besides, the marine airbag need little maintenance and can be used repeatedly.

Marine salvage airbag is another application of ship launching airbags . Marine Salvage Airbags is the toughest air lifting bags. It can be used as salvage pontoon for the supporting docks, and other floating structures. Also can be used to salvage the shipwreck, rescue the floating bridge and dock construction. It really come into own when marine salvage airbags employed in heavy duty salvage work under severe environment.

How to select marine airbags?

Marine airbags can be divided into winding type and lap type airbags, and winding type airbags are divided into high pressure explosion-proof type and ordinary type. What is the type of selection of Marine airbag we usually talk about? Which type of airbag is most suitable for the shipyard according to its own conditions?

Actually lap type air bag is an old process, and compared with the winding type of air bag is a new type of air bag production process, relatively safe and reliable, but also the current mainstream, so the choice should be inclined to the winding type more.

Secondly, the choice of air bag depends on the material, here is also the key, to choose nylon cord line, the use of low grade cord to do the air bag, which is easy to lead to leakage and even the danger of explosion; And the rubber must be pure natural rubber, so as to achieve the high pressure resistance of the air bag.

Thirdly, appropriate ship specifications should be selected. For example, if the width of the ship is 10m, airbags of 10m length should be selected, not 9m (too small), let alone more than 10m (wasteful of resources and money). If there is really no specific grasp, it is best to tell us the specifications of the ship, we will help to design a most appropriate ship airbag; In addition, the number of air bag layers must reach the standard, because if the ship is too big and the number of air bag layers is too low, it can not withstand high pressure, and there will be the risk of explosion.

The requirements of launching ship and relevant equipments.

1.Ship
The engineering work under water line shall wholly be finished, especially those equipments, valves and others that are to be installed at the openings under ship waterline,the installations should be approved by inspection. All the burrs, welding beading and the like on the ship bottom or appendages should be ground away. All the welds on the shell plate must pas inspection and tightness test. The main dimensions of the ship should be measured up and the mark of loadline must pass inspection. All the paint work of the shell plate has been finished.
2 Ramp way
The ramp way on which the airbags will rolling should be cleaned and be clear of sharp fends such as iron nail. The ramp way should be leveled and the level error from left to right should less than 80mm. The ground caved in should be filled up and the ground bearing capacity should be relatively equalized. The ramp made of mud land, sanded land, sands or concrete, however, its bearing capacity should be twice as big as the working pressure of airbags. The slope of ramp is to be determined according to the size of the launching ship and is generally no bigger that 1/7. In the range of the whole length of the ramp way, the shape may be of multiple combination with slope line, are line and others. However, the ship bottom should not contact the ground even when the airbags are at their lowest working height. The ramp way should extend into water for certain length.
3.Winch
In general, a slow winch is to be selected, its veering speed is about 9-13/m/min. The moving speed of a ship must not be more than 6m/min with the control of hauling force of winch wire. If the ship weight is less than 200t, the moving speed can be increased properly. The wire must be inspected and replaced regularity.

4.Air compressor
The type and capacity of the air compressor is to be selected according to the total volume of all the airbags provided for the launching and time required for air filling and the air pressure. The gas tank of air compressor should be installed with adjustable pressure limiting valve.

Our advantage

1. Special synthetic tire-cord layer material

Marine airbags are made with reinforced synthetic tire-cord layers, which have much better performance than those made with PVC coated fabrics.

2. High-Pressure Design

Marine airbags have a maximum working pressure of 0.25 Mpa. That means they can be used under 25m water-depth.

3. Strict quality management system

All the material used in production should be tested accoring to the requirement. Material failed the test is forbidden to be used. This ensures the high quality of our marine rubber airbags.

4. Warranty Period

Without misuse, the airbags from our company have a warranty period of 2 years
