inflatable marine airbags

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.

• 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. Anti-explosion design of end part.

• Product Advantage
• High Bearing Capacity

Inflatable rubber airbag’s main technical requirement is regulated in CB/T 3795--1996 published by China State Shipbuilding Corporation.

Our 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.

The synthetic-tyre-cord layer of OUR marine airbag adopts dipped Nylon-6 1400dtex/3-V2 tyre cord.

The strength & durability of airbag improves 20%, compared to polyester tire cord which is widely used by friendly competitors

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 .

Each layers of airbag are painting with specially formulated mucilage to dissolve dust & impurities.

The specially formulated mucilage

also higher the adhesiveness among each layers to guarantee the air tightness.

While most of friendly competitors cut this process in production to save manufacturing cost.

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.

High strength galvanized anti-release structure

casting metal part with chemlok coating.

chemlok coating strengthens the bonding between metal part and rubber body after vulcanization.

anti-release structure of the metal part makes the connection more tight.

Optimizing Structure Configuration

Hydraulic Blasting Test is an all-around ultimate test for the performance, material, structure design, manufacturing technique of marine airbags.

The testing result of Our Marine Airbag is beyond industrial standard

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.

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.

Heavy distortion phenomenon would cause delamination among airbag layers, then to cause more serious accidents.

Such dangerous distortion phenomenon in ship launching process never happened to Marine Airbags

Warranty
