Product Description

Ultra-Durable Marine Rubber Airbags: Flexible Solutions for Vessel Handling & Heavy Loads

Marine rubber airbags—an innovative breakthrough rooted in China's independent intellectual property—have redefined efficiency across maritime and heavy-industry operations. As a homegrown technological marvel, these airbags have revolutionized critical workflows through their unparalleled versatility and adaptability.

Their applications span a dynamic spectrum: From enabling seamless ship launching and hauling, where they gently cradle vessels of all sizes to ensure safe, precision-controlled movement, to facilitating accurate caisson lifting and relocation in port construction—eliminating the need for rigid, one-size-fits-all lifting frameworks. Beyond maritime realms, they excel in heavy-load hoisting, delivering stable, adjustable support for oversized or irregularly shaped cargo. They also serve as reliable buoyancy aids in underwater engineering, providing flexible buoyancy for subsea structures and pipeline installations.

A defining edge lies in their freedom from constraints: Unlike traditional methods tethered to fixed spatial limits or reliant on bulky machinery, marine rubber airbags operate seamlessly in confined or remote areas. This flexibility streamlines workflows by slashing setup and maneuvering time while driving substantial cost reductions—minimizing expenses tied to heavy equipment rentals, labor-intensive logistics, and project delays. In essence, they transform complex operations into agile, cost-effective processes, cementing their role as an indispensable tool in modern maritime and industrial projects.

Advantage

1.Special Synthetic Tire Cord Layer Material

Our "rescue tire" incorporates a specialized synthetic tire cord layer that outperforms PVC-coated fabrics by a significant margin. This high-grade material delivers superior toughness and extended durability, making it highly adaptable to complex working conditions.

2.High-Pressure Design

The fishing pipe boasts a maximum working pressure of 0.25Mpa, allowing it to operate at depths of up to 25 meters. This robust high-pressure capacity ensures stable performance in deep-water environments, effectively expanding its range of applications.

3.Integral Screw-Type Wrapped Rescue Airbag

Our "ship rescue airbag" is a fully enclosed tubular structure with tapered ends, crafted using advanced integral screw technology. This precision manufacturing process eliminates the need for welds, resulting in a structure that offers greater strength compared to RF-welded salvage airbags—significantly enhancing reliability during critical rescue operations.

4.Comprehensive Accessory Package

The rescue kit comes complete with nylon straps and shackles engineered with a 6:1 safety factor. These premium accessories provide robust support for rescue missions, ensuring maximum operational safety at all times.

Technical requirements for marine airbags:

According to CB/T 3795-1996, marine airbags should meet the technical requirements

1. Size deviation
The deviation of diameter and effective length is -2%---+2%,
The deviation of the total length is -4%---+4%
2. Elastic deformation
When using 1.2 times the working pressure as the experimental pressure, the diameter deformation is not more than 5%

3. Safety factor
Safety factor is not less than 4.5

4. Airtightness
Inflate for 1h, the pressure drop is not more than 5%
5. Appearance requirements
Linear smooth, no cracks and bubbles, heavy skin, mixed impurities and obvious dirt and other visual defects.

6. Safety inflation device
The safety valve should be installed on the capsule, and the trip pressure of the safety valve should be 1.25 times of the working pressure.
