Introducing the Unmatched Marine Rubber Airbags
Marine Our rubber airbags are a groundbreaking innovation, boasting proprietary Chinese intellectual property rights, setting a new standard in maritime solutions. It offers versatile applications, including ship launching & upgrading, caisson lifting & moving, heavy weight lifting, and providing buoyancy aid for underwater engineering projects. These exceptional marine rubber airbags are free from the constraints of space and heavy machinery, dramatically reducing the construction period and saving substantial funds.
Marine Rubber Airbag Applications
Ship Launching & Upgrading
With over two decades of development in China, marine rubber airbags have proven to be the pinnacle of reliability and stability for ship launching and upgrading, suitable for vessels ranging from small flat boats to massive ten-thousand-ton ships. Moreover, marine rubber airbags have gained international acclaim and are widely recognized by foreign dockyards, shipyards, and port/harbour construction companies worldwide. Ship launching & upgrading with marine rubber airbags is enthusiastically endorsed in markets such as America, Europe, and Southeast Asia.
Weight Lifting & Moving
Marine rubber airbags are also ideal for caisson lifting, launching, moving, and transporting within port construction projects, offering unmatched versatility.
Buoyancy Aid & Salvage
Thanks to their substantial buoyancy force and load-bearing capacity, marine rubber airbags are extensively utilized in sunken vessel salvage operations and as reliable Buoyancy Aids.
Technical Requirements
In accordance with CB/T 3795--1996, marine rubber fenders must adhere to the following stringent 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, ensuring robust performance under demanding conditions.
Air Tightness: depressurization < 5% after 1-hour inflation, exemplifying superior seal integrity.
Surface Quality: flawless fairing line shape, devoid of cracks, bubbles, double skin, impurities, and dirt or any other visible defects.
Anti-explosion design ensures safety at the end part.
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.
