ISO14409 Standard Vulcanized Inflatable Marine Rubber Airbag
Product Introduction:
Marine rubber airbags are widely used in launching and landing ship/ boat/vessel, lifting and moving heavy goods, salvaging stranded boats. Marine airbags are very popular with shipyard, ship owner, and marine supplies company now.
The history of marine rubber airbag dates back to 1981. Xiao Qinghe ship repair and building shipyard, located in Jinan city of Shangdong Province, launched a 60 DWT tank barge with airbag suspension on January 20, 1981. Seven airbags were deployed in that project. One was 2 meters in diameter and 6 meters long and used for elevating. The remaining six airbags were 0.8 meters x 6 meters long and acted as the rollers. The first intention of that trial launch was to develop a prompt, less landform limited ship launching method for warfare purposes.
Technical requirements for marine airbags:
According to CB/T 3795-1996, marine airbags should meet the technical requirements
1. Size deviation
The deviation of diameter and effective length is -2%---+2%,
The deviation of the total length is -4%---+4%
2. Elastic deformation
When using 1.2 times the working pressure as the experimental pressure, the diameter deformation is not more than 5%
3. Safety factor
Safety factor is not less than 4.5

4. Airtightness
Inflate for 1h, the pressure drop is not more than 5%
5. Appearance requirements
Linear smooth, no cracks and bubbles, heavy skin, mixed impurities and obvious dirt and other visual defects.
6. Safety inflation device
The safety valve should be installed on the capsule, and the trip pressure of the safety valve should be 1.25 times of the working pressure.
