1,Marine Rubber Airbag Introduction

6000 years ago, our ancestor begin to use log-rolling method to lift and move weights,which is still widely used in daily production and actual life nowadays. Marine rubber airbag is designed with soft rubber to lift and carry weights, based on log-rolling method.Marine rubber airbag is an innovative product of Chinese own proprietary intellectual property rights. It has wide application like ship launching & upgrading, caisson lifting &

moving, heavy weights lifting, underwater-engineering buoyancy aid. The marine rubber airbag is not limited to space and heavy machinery, which could efficiently shorten the construction period and save lots of funds.

2,Marine airbag function

2.1. Shipping launching and upgrading

2.2. Weight Lifting & Moving

Marine rubber fend could be applied to caisson lifting, launching, moving and transporting in port constructing projects

2.3. 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.

3,Technical Requirement

According to CB/T 3795--1996, marine rubber fender should meet the following

requirements.

3.1. Dimensional Deviation:

Diameter & Effective Length Deviation: ±2%

Total Length Deviation: ±4%

3.2. Amount of Elastic Deformation: diameter deformation amount ≤ 5% under 1.2

times working pressure.

3.3. Safety Factor: >4.5

3.4. Air Tightness: depressurization < 5% after 1hour inflation

3.5. Surface Quality: fairing line shape, no crack, no bubble, no double skin, no impurities,

no distinct dirt and other apparent defect.

3.6. Anti-explosion design of end part

4,Marine airbag production standard

The international airbag production standard is ISO14409, which strictly regulates the structure design, material, testing, packaging and storage of the airbag. The airbags in our factory are strictly produced in accordance with the ISO14409 standard and are strictly Control production quality.

5,quality inspection

Before leaving the factory, each airbag must undergo a strict appearance inspection and airtightness test to test whether there is any air leakage in the airbag within a specified period of time and to issue a factory inspection report.
If there are any unqualified airbags during the inspection process, they will be returned to the factory for redoing.

6,Marine airbag packing

the airbags are delivered with stretch film and packing cloth wrapped around the outside to ensure the safety of the airbags in the transportation process.

6,Warranty

12month

7,Product Advantage

7.1. High Bearing Capacity

7.2. 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.Our improved the manufacturing technique and raw material formula to strengthen kneading-resistance capability of the airbag and avoid worse accident .

7.3. 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.

Our 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.

7.4. 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.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.

7.5. Higher Flexibility and Shock Absorption Capability

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.
