Marine Ship Launching Lifting Rubber Airbag ISO Standard

Hot Sale Marine Ship Launching Lifting Rubber Airbag

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. If you don't know the exact size you need, it is best to tell us the specifications of the ship such as the length, width and weight, we will help to recommend and 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.

Florescence ship rubber airbag complies 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, there's no need to worry about the construction of launching facilities; besides, the marine airbags need little maintenance and can be used repeatedly.

Diameter(D): From 0.6m to 2.8 m
Effective Length(EL): From 5.0m to 25.0 m
Total Length(TL): From 7.0m to 28.0 m
Standard Number of Layers: Usually 3-10 layers

How has the technology advanced since then?
Over the past twenty years, the airbag ship launching system has made advancements in not only the airbag, but also the ship launching/landing technology. The first generation airbags used a rubber dipped canvas as a reinforcement layer to form the air chamber trunk. Two cone-shaped molds were then used to make the ends and everything was stuck together.
With today’s airbags, the whole-enlacing-technology used for manufacturing is done together. Rubber dipped synthetic-tyre-cords are used as the reinforcement layers with the trunk and two cone-shaped ends made at the same time.Everything is then-laced together, so the airbag doesn’t have any joints. Due to the development of rubber chemistry, the performance of the rubber employed in the latest airbags is highly enhanced and about 15 times that of the first generation bag with the same specifications.
The launching and landing technology has also developed. In the beginning, only small and flat bottom ships located on a fabricated slope could be launched with airbags. Now this technology is more flexible and less limited by the ship and landform. Now any type of ship with a DWT below 55,000 and in a place with enough launching space can be launched using airbags. The launching slope even can be sloped upward. It has really developed into a cutting edge technology for launching ships, and especially useful for some marine emergencies.

FAQ
Q: How should marine airbag be maintained when storing?
A: When the air bag is unused for a long time, it should be washed and dried, filled with talcum powder and placed in a dry, cool and ventilated place.

The air bag should be stretched out flat, not stacked, also not on the air bag pile pressure heavy. Keep airbags away from heat.

Airbags should not come into contact with acids, bases, oils and organic solvents.
