Airbags
Specification of Marine Airbags
When classified by the diameter, the usual sizes of airbags are
0.8m, 1.2m,1.5m, 1.8m , 2.0m and 2.5m. The maximum length can be
24m. The diameter of the airbag depends on the height of the
docking blocks. The most important part of the airbag is to lifting
the ship from the blocks. The ship should be wholly lift up and
higher than the blocks. Therefore, the diameter of airbags should
be 0.5m-0.7m longer than the height of the blocks. Otherwise, the
capacity of the airbag cannot be reached. Usually, airbags with the
diameter less than 1.2m are used for small boats. If the height of
blocks is or less than 0.9m, airbags with 1.5m diameter is
suitable. If the height is or more than 1m, the diameter of airbags
should be or more than 1.8m.

Introduction of Marine Airbags
Marine airbag are widely used for ship docking and launching, large
heavy objects lifting and moving, sunken ship salvaging and
stranding rescue etc. Compared with the traditional sliding plate
and slipway, airbag has the feature of saving time and labor, less
investment, flexible, safe and reliable. etc.
Our factory has invested a large amount of labor, material and
energy, brought together much professional knowledge in rubber,
chemical etc. invested a high strength, overall winding high
pressure anti-explosion type airbag.
Advantages
it’s internal skeleton structure is more scientific, there’s no
joint in the whole airbag body, the skeleton materials’ resistant
to pull force can be fully used. Overcoming the weakness of the
uneven internal pressure that acts on the airbag body, also
avoiding the problem of peeling off of the layers, bubbling and the
danger of a sudden explosion. By many times strict test, the brute
force, tensile strength , anti-aging, abrasion resistance etc.
indicators of our airbag ranked the forefront of industry. All the
natural rubber we used are 1L,3L in best quality , to ensure the
sturdy and durable of the product and safety in use; the production
technology adopted the advanced technological standard in industry;
the complete testing equipment in our company ensure that the raw
material, semi-manufactures and finished products pass tests one by
one, and make airbags have good bearing capacity, good air
tightness, easy to repair and long lifespan, safe and reliable, the
product is widely used throughout the world and win the praise of
customers
Airbag Structure and Accessories
Marine airbag are widely used for ship docking and launching, large
heavy objects lifting and moving, sunken ship salvaging and
stranding rescue etc. Compared with the traditional sliding plate
and slipway,airbag has the feature of saving time and labor, less
investment, flexible, safe and reliable. etc.
1. Outer rubber layer
The outer rubber layer that covers the outside of marine airbag to
protect under layer from abrasion and other external forces. This
compound has sufficient tensile and tearing strength to withstand
any condition and hard usage.
2. Synthetic-tire-cord layer for reinforcement
The reinforcement cord layers, which are made of
synthetic-tire-cord commonly used in tires, are arranged at ideal
angles to hold the internal pressure and distribute stress evenly.
So they can provide strong efficient reinforcement.
3. End fittings
End fittings include Pipe fitting at the inflation end and Pull
ring at the sealing end.

Bearing Capacity
As a soft elastic body, an airbag shape can change with ship bottom
shape, ramp. Ship bottom width and airbag length and location, etc.
during ship launching. So airbag bearing area and capacity also
change. Users should calculate airbag bearing area and capacity
according their application.
Bearing capacity F=PS
Where:
P- Pressure in airbag(Mpa)
S-Contact area between ship bottom and airbag(m2)
Contact area S=π×(D1-D2)/2
D1: Height of inflated airbag
D2: Height of deflated airbag
S: Contact area between flattened airbag and floor, namely area
between airbag and ship bottom
Special attentions during the use of the airbag
1. Control the working pressure strictly and it’s not allowed to
exceed the working pressure.
2. There shall be no sharp and protruding hard object on the
contact surface with the airbag in case it punctures the skin of the airbag.
3. Try to avoid distortion happened to the length direction of the
airbag.
4. Empty charge test shall be performed if the airbag is not used
for a long time or reused after repair. Charge pressure if the airbag shall be the same as
the test pressure valve when delivered. Inspectors shall be at least 3 meters away from the
airbag. For airbag recovered from large damage, its working pressure shall be reduced
reasonably. Besides, annual check shall be conducted on airbags which are used often.
5. Do not drag the airbag on the ground.
