Inflatable Marine Black Rubber Ship Launching And Lifting Airbag

1.marine airbag introduction

Marine Rubber Airbag is China independent intellectual property rights of innovative products, the products are mainly applied to ship launching and landing, weight lifting, handling, installation of underwater buoyancy aid etc. Nowadays, Marine rubber airbags are widely used in the world. The Products are less limited by space, no large mechanical equipment, can shorten the working period and save the unnecessary cost. Through years of development practice, marine rubber airbag is become more safety, effective and green environmental protection.

Framework:

“HENGER” airbag structure are consist of the outer rubber + synthetic cord reinforced rubber layers.Its shape characteristics: central body cylindrical + tapered on both ends. Cord layers: 4,5,6,7,8,9,10,11,12 layers.

2. Technical Requirement

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

• Dimensional Deviation:

Diameter & Effective Length Deviation: ±2%

Total Length Deviation: ±4%

• Amount of Elastic Deformation: diameter deformation amount ≤ 5% under 1.2 times working pressure.
• Safety Factor: >4.5
• Air Tightness: depressurization < 5% after 1hour inflation
• Surface Quality: fairing line shape, no crack, no bubble, no double skin, no impurities, no distinct dirt and other apparent defect.
• 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.

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.

The synthetic-tyre-cord layer of Henger 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.

Henger 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.

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.

• 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

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.

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

The testing result of Henger 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.

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.

• 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.

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 Henger Marine Airbags

6. Marine Rubber Airbag Application

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.

• Weight Lifting & Moving
• 

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

• 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.
