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.
 
Specifications(ISO14409 Standard)
Usually the diameter and number of skeleton layers of the airbag are provided by the customer.
Besides, we can also recommend appropriate size according to the information provided by customers, such as ship tonnage and ship working height, etc..
