Integral Wound လေအိတ်

As a trusted China supplier of Integral Wound Airbags within the industry, the Sunkai factory serves global B2B buyers with consistent product quality and efficient production capabilities. We are the preferred partner for ship launching operations and heavy-load lifting projects. Sunkai utilizes high-strength rubber and reinforced layering materials to ensure superior load-bearing performance, excellent resistance to aging, and exceptional airtightness, resulting in highly durable, safe, and reliable products.

Product Manufacturing Process

Sunkai Integral Wound Airbags are manufactured using an integral winding process, resulting in a compact structure with uniform stress distribution. Free from the traditional seams found in spliced designs, they offer superior pressure stability. These integrally wound airbags feature a robust structure and stable load-bearing capacity, while also being highly wear-resistant and durable. Primarily utilized for ship launching, heavy object lifting, and heavy-load bearing applications, they are safe, reliable, and convenient to use.

Product Specifications

Application Scenarios

Leveraging an integrated spiral-winding and braiding process, our product features airbags that are highly resistant to abrasion and tearing. Sunkai offers customizable specifications tailored to client requirements, catering to the project procurement and long-term supply needs of various domestic and international shipyards and shipping enterprises. The following are the relevant application scenarios:

1. Used for ship launching and docking operations, lifting and shifting within shipyard dry docks, and the salvage and refloating of stranded vessels;

2. Suitable for the transfer of cargo and the provision of safety protection for personnel transit in shallow-water areas lacking docking piers;

3. Applicable for ship emergency evacuation protection and marine buoyancy support/cushioning projects, while simultaneously meeting operational demands such as port collision prevention assistance and the suspension and load-bearing support of heavy objects.

Usage Precautions

As a primary source manufacturer and specialized supplier in China, Qingdao Sunkai Marine Supplies Co., Ltd. reminds purchasing clients that when utilizing custom-made "Integral Wound Airbags," it is imperative to strictly adhere to the following operational guidelines:

1. Pre-Inflation Inspection: Carefully inspect the surface of the airbag prior to inflation. Ensure there is absolutely no direct contact with sharp gravel, steel plate burrs, or welding slag, to prevent scratching of the integral wound structure which could lead to air leakage or structural damage. The placement site must be level and clean; a protective cushioning layer should be laid down before commencing operations.

2. Inflation Control: strictly inflate the airbags in accordance with the standard pressure specifications established at the factory. Over-pressurization and indiscriminate pressure increases are strictly prohibited. For vessels of varying tonnage or specific lifting/buoyancy requirements, please contact Sunkai to arrange for customized parameters, thereby preventing deformation or bursting caused by improper pressure levels.

3. Load Distribution: During ship launching/docking, lifting/shifting operations, or stranding rescue missions, the load applied to the airbags must be distributed evenly and symmetrically. Concentrated single-point overloading is strictly forbidden. Furthermore, dragging or pulling the airbags at an angle is prohibited to prevent fracture of the internal woven layers, which would compromise the overall load-bearing capacity.

4. Environmental Protection: When deployed outdoors for extended periods, avoid exposure to environments containing strong acids, strong alkalis, or corrosive oils. After use in seawater, promptly rinse the airbags with fresh water and allow them to dry. When storing in a warehouse, keep them away from direct light, moisture, high temperatures, and open flames to maximize the service life of the airbags.

5. Handling and Storage: Handle and stow the airbags with care, folding them neatly and systematically. Rough handling—such as violent crushing or stacking heavy objects on top—is strictly prohibited. Shipyards and shipping companies engaged in long-term supply partnerships with Sunkai may contact our factory to obtain exclusive maintenance manuals and technical guidance.

6. Inspection and Maintenance: Periodically conduct airtightness tests on older airbags. If any bulging, cracking, or slow air leakage is detected, immediately cease use and perform necessary repairs. Should replacement or upgrading be required, Sunkai offers on-demand customization of new integral wound airbags with identical specifications to ensure continued operational safety and regulatory compliance.
