Marine Rubber Airbags
Marine Our rubber airbag stands as a beacon of innovation, an exclusively designed product that embodies the proprietary intellectual property rights of China. It boasts a vast array of applications, including ship launching and upgrading, caisson lifting and moving, heavy weight lifting, and providing buoyancy aid for underwater engineering. This exceptional marine rubber airbag transcends the limits of space and heavy machinery, allowing for a significant reduction in construction time while delivering substantial cost savings.
Marine Rubber Airbag Applications
Ship Launching & Upgrading
Having thrived for over 20 years in China, marine rubber airbags have proven to be the quintessential technique for the launching and upgrading of ships. They are suitable for a diverse range of vessels, from small flatboards to colossal ships weighing tens of thousands of tons. Moreover, marine rubber airbags are increasingly favored by international dockyards, shipyards, and companies involved in port or harbor construction. Ship launching and upgrading techniques utilizing marine rubber airbags are highly esteemed in markets across America, Europe, and Southeast Asia.
Weight Lifting & Moving
Marine rubber airbags are ideal for the lifting, launching, moving, and transporting of caissons in port construction projects.
Buoyancy Aid & Salvage
Thanks to their buoyancy force and impressive load-bearing capacity, marine rubber airbags are indispensably used in the salvage of sunken vessels and as Buoyancy Aids.
Technical Requirements
In alignment with CB/T 3795--1996, marine rubber fenders must satisfy the following precise requirements.
Dimensional Deviations:
Permissible Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
Amount of Elastic Deformation: diameter deformation amount ≤ 5% at 1.2 times working pressure.
Safety Factor: >4.5
Air Tightness: pressure reduction < 5% within 1 hour of inflation
Surface Quality: must display a streamlined shape, free from cracks, bubbles, double skins, impurities, or noticeable contaminants and any apparent defects.
Advanced anti-explosive design for end parts.
Product Advantages
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.
Optimization to Perfection Innovative Structure Configuration
Hydraulic Efficiency and Versatility BLong-lasting Durability Test is a comprehensive and ultimate examination of the performance, material quality, structural design, and manufacturing techniques of marine airbags, ensuring they are fit for rigorous applications.
The assessment results of Our Marine Airbag exceed the standards set by the industry, showcasing its superiority.
Superior Abrasion-resistance Performance and Exemplary High Ageing Resistance
The airbag operates under harsh and challenging conditions, enduring prolonged sunlight exposure, seawater corrosion, and pollution from impurities. Its surface must boast exceptionalabrasion resistance, resistance to ageing, and excellent corrosion resistance.
Crafted from natural rubber with specially formulated ingredients and a distinctive manufacturing approach, the airbag performs admirably in the aforementioned adverse conditions.
Enhanced Flexibility and Superior Shock Absorption Capability
The airbag is crafted using a unique integral twining technique. With a uniform wall thickness and a secondary seam at the overlap joint, the airbag flexibly mitigates structural stress and reduces ship launching risks when rolling on slopes and uneven paths.
