Marine airbag's specifications

Select the airbag's effective length not less than the maximum width of vessel or anything you want to move by airbags. But when you arrange two rows of airbags keep in mind to calculate the total length to avoid contact of airbags in two rows. The total length of airbags can be estimated to be effective length plus diameter. It says an airbag whose effective length is 16 meters and diameter is 1.5 m then its total length is 17.5 m.

Diameter of airbag is decided by the height of your vessel's support blocks. If the support block is 1 m high, then you should choose airbag's diameter not less than 1.5 m. If you get 1.5 m high blocks, the airbag with 2m diameters will suits you well.

Marine Airbag Application

Marine airbags are widely used for ship launching, heavy transportation and marine salvage nowadays. Marine airbags are often called ship launching airbags that indicate the most popular application of these heavy duty airbags is for ship launching. It is estimated that more than 80 percent new built ships who’s DWT below 60,000 are launched by marine airbags.

The structure of Marine Airbag

The structure Nanhai No. 1 Marine airbag for ship is shown in Fig. 4. It consists of a bag body and end-iron component. The bag body is made from vulcanization of base rubber and reinforced fiber material. The end-iron component is made of metal materials and connected to the bag body firmly.

Major Strengths of Marine Airbag:

1.High safety level: equipped with a reliable safety valve, our airbags can stand the maximum pressure up to 4 times that of the operating pressure.

2.Good air tightness: pressure decreases less than 10% for a period of 24 hours.

3.Long lifespan: it is guaranteed that our airbags can sustain their designed operating pressure for 3 years.

4.A complete set of solutions is available.

Marine Airbag description

Ship launching rubber marine airbags technique was found to be versatile and flexible in marine engineering fields. Rubber Airbags can lift up heavy like jacks and move it forward,act as pneumatic rollers. Airbags can roll over pits and knuckles, so they have less demands of the ground or ramp. Different from rigid trolleys, launching airbags can be compressed at different ratio, thus they can absorb the impact energy emerges in some structure launching projects.

Our Marine Airbag

Founded in 2003, Nanhai Airbag is a full-service provider of airbags and pneumatic fenders, covering R&D, manufacture and distribution. Our airbag products are used for ship launching, buoyancy, and heavy lifting and moving with remarkable advantages over traditional steel-based methods.
