Marine Rubber Airbags
Marine Our marine rubber airbag represents a groundbreaking innovation, exclusively developed with Chinese proprietary intellectual property rights, showcasing the pinnacle of engineering excellence. It boasts a versatile range of applications, including ship launching & upgrading, caisson lifting & moving, heavy weight lifting, and serving as a buoyancy aid for underwater engineering endeavors. The marine rubber airbag transcends the limitations of space and the need for heavy machinery, offering a significant reduction in construction time while delivering substantial cost savings.
Marine Rubber Airbag Applications
Ship Launching & Upgrading
With over 20 years of development in China, the marine rubber airbag has proven to be the most reliable and stable technique for ship launching & upgrading. It caters to a vast range from modest tons of flat boards to colossal ten-thousand-ton ships. Marine rubber airbags have gained widespread recognition and endorsement by international dockyards, shipyards, and port/harbour construction companies. Ship launching & upgrading using marine rubber airbags is highly endorsed in key markets, including America, Europe, and Southeast Asia.
Weight Lifting & Moving
Marine rubber airbags are adeptly applied to caisson lifting, launching, moving, and transporting within port construction projects, offering unparalleled efficiency.
Buoyancy Aid & Salvage
Given the buoyancy and load-bearing capacity of marine rubber airbags, they are extensively employed in sunken vessel salvage operations and act as indispensable Buoyancy Aids.
Technical Requirements
As per CB/T 3795--1996 guidelines, marine rubber fenders must adhere to the following criteria.
Dimensional Deviation:
Diameter & Effective Length Deviation: ±2%
Total Length Deviation: ±4%
Amount of Elastic Deformation: diameter deformation must not exceed 5% under 1.2 times the working pressure.
Safety Factor: >4.5
Air Tightness: depressurization must remain <5% after 1-hour inflation
Surface Quality: Ensuring an impeccable fairing line shape without cracks, bubbles, double skin, impurities, or any distinct dirt or other apparent defects.
Anti-explosion design is meticulously incorporated into 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.
Optimization Excellence Robust Structural Configuration
Advanced Hydraulic Mechanism Blong-lasting durability Test serves as the ultimate comprehensive evaluation of our marine airbags' performance, material quality, structural design, and superior manufacturing techniques.
Results from the testing indicate that Our Innovative Marine Airbags surpass industry standards with remarkable performance.
Excellent Abrasion-resistance Performance and Superior High Ageing Resistance
These airbags excel under harsh conditions, enduring prolonged sunlight exposure extreme seawater corrosion, and contamination by impurities. The surface must demonstrate exceptionalabrasion resistance, ageing resilience, and corrosion resistance.abrasion resistance, enhancing their endurance.
Constructed from natural rubber enriched with special formulations and crafted using unique manufacturing methods, the finished airbags perform exceptionally well in adverse conditions.
Enhanced Flexibility and Shock Absorption Capabilities
The airbag is expertly crafted using a unique integral twining technique. Uniform wall thickness with a secondary overlap seam ensures that when rolling on uneven ship paths, the flexible airbag aids in stress reduction and minimizes launch risks.
