Dry Dock Launching Lifting Ship And Floating Salvage Marine Airbag
Marine Rubber Airbags
Ship Launching Rubber Airbag have been widely used worldwide. There
are many technologies for producing marine airbags. Launching
airbags are innovative products with independent intellectual
property rights in China. They are mainly used for ship landing and
underwater buoyancy. The product uses small space, simple
technology, and saves unnecessary costs. Through years of
development and practice, marine rubber airbags have been very
advanced in the field of ship launching.

Product Advantage
1. New end explosion-proof design
Air leakage at the junction area of metal parts and rubber parts
increases as the pressure of the airbag increases. After several
times of use under high working pressure, the Ship Launching Rubber
Airbags will rupture and the metal parts will injure workers.
Henger has improved the bonding strength and air tightness between
the main part of the rubber and the metal part at the end, and
invented a new explosion-proof design for the end of the airbag.
The Henger airbag works well under higher working pressure. There
are no potential safety hazards.
2. High-strength galvanized anti-drop structure
Cast metal parts with galvanized coating. Enhance the bonding force
between the metal parts and the rubber body after vulcanization.
The anti-release structure of the metal parts makes the connection
closer.

Marine Launching Airbag test
1. Blasting test
Through the burst test, the minimum burst pressure value of the
airbag can be tested. For the sake of safety, because the Ship
Launching Rubber Airbag is a pressure vessel, it must be inflated
while the airbag is inflated until the airbag bursts. The water
pressure during the airbag sandblasting process should be greater
than or equal to the value listed in the standard performance
table.
1. Compression recovery test
If the recoverability of marine rubber airbags is to be verified,
the airbags should be compressed and released quickly and
repeatedly in a short period of time. Due to the limitation of the
length of the airbag and the limitation of the compression recovery
equipment, the compression recovery test can be achieved by
reducing the same number of layers. Inflate the airbag so that the
internal pressure reaches the pressure of the airbag performance
data. The airbag is compressed vertically until the compression
deformation reaches 75%. Keep this state for 1 minute. Then the
pressure is released and the balloon diameter should return to more
than 97% of its original diameter within 5 minutes.
