Advantage airbag for boat launching
1. Advanced manufacturing technology
2. Best imported natural rubber from Thailand and Malaysia
3. Safety and reliability
4. Good air tightness
5. Saving labor and cost
6. Long using time
Application Marine Air Bag
1. Ship launching and landing
2. Heavy lifting and moving
3. Ship salvage rescue project
Heavy goods handling:
Marine airbags are widely used in caisson lifting, transportation,
launching and other fields in port construction, as well as
component displacement and launching.
Floating and salvage:
Marine airbags can generate greater buoyancy and strong
load-bearing capacity, and are now widely used in rescue of
stranded ships and other buoyancy and salvage fields.
Airbag packaging and transportation:
According to the provisions of the CB/T 3795-1996 of the People's
Republic of China Ship Industry Standard, the packaging,
transportation and storage of marine airbags should comply with the
following standards:
1. Packaging
Folded and packed with plastic woven bags.
2. Transportation
Airbags should be lifted, lifted, and rolled in an inflated state
when transported on short distances. It is strictly forbidden to
drag on the ground.
The airbag should be folded and fixed to the tray during
long-distance transportation, with a cushion underneath, and
wrapped with a wrapping film on the outside.

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.
The development history of marine airbag:
According to related records, humans have been using the rolling
wood principle to carry heavy objects more than 6,000 years ago.
People still use the rolling wood principle to carry heavy objects
in daily production and life. Marine airbag is a flexible heavy
vehicle designed according to the principle of rolling wood.
In the 1980s, due to the manufacturing process and materials of
airbags, the weight of airbag launching ships was between 100 tons
and 500 tons.
In the early 1990s, people made innovations in the process and
materials of airbag manufacturing: nylon cords replaced canvas as a
new skeleton material, and a new type of integral winding
manufacturing process was developed.
Some marine airbag manufacturers still use the old production
technology of lap type. It is generally believed that the
integrally produced marine airbag is more reasonable in structure
and has a greater safety factor and bearing capacity.
Water-filled blasting test is an important method to check the
performance of marine airbags.
