2. Product Introduction of Marine Rubber Airbag
Marine Rubber Airbag also known as rubber airbag, ship air bags, ship launching airbag,
ship salvage airbag, boat salvage airbags, inflatable airbag, ship
lifting bag, air balloon, made by rubber & multi layer of
rubber-dipped tyre fabric.
Marine Rubber Airbag are widely used in launching and landing ship/ boat/vessel,
lifting and moving heavy goods, salvaging stranded boats.
Marine Rubber Airbag are very popular with shipyard, ship owner, and marine supplies
company now.
Marine Rubber Airbag has longer service life.
3.Inflatable Rubber Airbag Application
a. Ship Launching & Upgrading
With more than 20 years development in China, marine rubber airbag
is proved to be the most reliable and stable technique for ship
launching & upgrading. It is applicable from tons of flat board to
ten thousand tons of huge ship. Meanwhile, marine rubber airbag is
also widely acknowledged by foreign dockyards, shipyards,
port/harbour construction companies. Ship launching & upgrading
technique with marine rubber airbag is also highly promoted in the
markets, such as America, Europe, Southeast Asia.
b. Weight lifting & moving
Marine rubber fend could be applied to caisson lifting, launching,
moving and transporting in port constructing projects.
c. Buoyancy Aid & Salvage
Because marine rubber airbag has buoyancy force and load-bearing
capacity, it is also widely used in sunken vessel salvage and
Buoyancy Aid.
4.Technical Requirement
According to CB/T 3795--1996, marine rubber fender should meet the
following requirements.
1. Dimensional Deviation
Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
2. Amount of Elastic Deformation: diameter deformation amount ≤ 5%
under 1.2 times working pressure.
3. Safety Factor: >4.5
4. Air Tightness: depressurization < 5% after 1hour inflation
5. Surface Quality: fairing line shape, no crack, no bubble, no
double skin, no impurities, no distinct dirt and other apparent
defect.
6. end part anti-explosion design
5.Product Advantage
a. High bearing capacity
Inflatable rubber airbag’s main technical requirement is regulated
in CB/T 3795--1996 published by China State Shipbuilding
Corporation.
Henger adopts new rubber formula and high-strength enhanced
synthetic-tyre-cord layer, which improves the airbag’s bearing
capacity two times more than CB/T 3795--1996 standard
b. High kneading-resistance capability
When the airbag is rolling under the ship bottom, it will suffer a
“kneading force” from ship bottom and ground because of not uniform
rolling speed, which could case problems like delamination, layer
buckling, etc.
Henger improved the manufacturing technique and raw material
formula to strengthen kneading-resistance capability of the airbag
and avoid worse accident .
c. New anti-explosion design of end part
The possibility of air leakage in the joint area of metal part and
rubber part is also increasing as working pressure of airbag is
added. After using for times under high working pressure, the
airbag would burst and metal part would hurt workers.
Henger invented new anti-explosion design of the airbag end part,
increasing the bonding strength and air tightness between rubber
body part and end metal part. Henger airbag is working very well
under higher working pressure without
potential
safety
hazard.
d. Optimizing structure configuration
Henger built a strength and Intensity Model to test compression
performance, stress intensity and direction. After testing for many
times, we got the stress
changeing regularity and optimized structure configuration design. The new optimized
airbag successfully passed blasting experiment and achieved good
performance in practical use.
e. Good Abrasion-resistance performance and high ageing resistance
The airbag is working under bad and poor condition, suffering from
long time sunlight exposure, seawater
corrosion, impurities pollution, etc. The surface of airbag must be equipped
with high capability of abrasion resistance, ageing resistance,
corrosion resistance.
Henger airbag is made of natural rubber with special ingredients
and unique manufacturing method. The finished airbag could working
very well under above mentioned bad and poor working condition.
f. Higher flexibility and shock absorption capability
Henger airbag is manufactured with unique integral twining
technique. The airbag wall thickness is uniform with secondary seam
in overlap joint. When rolling in slope and uneven ship path, the
flexible airbag is helpful to reduce structure stress and ship
launching risk.
