NANHAI - SHIP LAUCHING AIRBAG
NanHai-Ship Launching Airbag, among the earliest manufacturers of ship airbags, has led and innovated ship launching
airbag technology with its ultra-bigh pressure airbags with working pressure as high as 800KPa and anti-puncture airbags.
NanHai-Ship Launching 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.

The arrangement of Synthetic-Tyre-Cord reinforcement layers is showed below. All materials shall be vulcanized firmly.
1. Airbag Cylindrical Body
2. Airbag Conical Head
3. Airbag Air Inflate End
4. Airbag Drag End
D. Dimeter of Airbag
LoA. Overall Length of Airbag
L. Effective length of Airbag
D1. Free State Height
H. Operating State Height
W. Operating State Breadth
Normally when we say the length of the airbag, we mean the Effective Length
MAJOR STRENGTHS OF NANHAI-MARINE AIRBAG
NanHai - Pneumatic Fender can totally meet the ISO 14409 standard
1. More safety: Nylon-6 Dipped Cord fabric, 3chords, single strength>313N, 1.5times than commons

3. More longer lifetime: 100% natural rubber, the lifetimes is at least 2 or 3 times than commons
4. Better air tightness: Guarantee 72 hours(3days) no air leakage
5. Different airbag size stock available, quick delivery
6. No harm to the environment, Time & money saving
7. Wear resistance and anti aging, Long time service life can be reused many times
APPLICATION OF NANHAI-MARINE AIRBAG
1. For ship upgrading, conversion or new/repair launching
2. Marine airbag for salvaging sunken ship or heavy immersed steel structure
3. For hoisting and transporting heavy goods up to 10,000 tonnes structure on land
4. For heavy lifting
5. For tunnel culverts to stop leaks
