Products Description
What Are Marine Launching Pneumatic Airbags?
Marine Launching Pneumatic Airbags go by various names, including roller bags, launching air balloons, inflatable marine airbags, air lift bags, and salvage bags. These are specialized marine rubber air bags primarily used for crucial marine operations such as launching marine vessels, facilitating ship landings, or enabling haul - outs. Additionally, marine rubber airbags have a wide range of applications. They are extensively used in loading, floating, lifting, and moving sunken ships, as well as salvaging stranded boats.
These airbags are constructed in a long cylindrical balloon shape. They consist of heavy - duty synthetic - tire - cord layers, which are sandwiched between inner and outer rubber layers. This robust construction provides the necessary strength and durability to withstand the significant forces involved in marine operations.
An Innovative Ship - Launching Technology
Marine launching or upgrading using marine airbags represents an innovative approach to ship launching. Traditional ship - launching methods like "end - on launching", "side ship launching", and "float - out" have their limitations. For instance, side - launch often comes with the constraint of a fixed launching track. However, the use of marine airbags overcomes these disadvantages.
This flexible marine - launching technology has gained acceptance in numerous shipyards around the world. It offers several notable advantages. Firstly, it saves time as the setup and operation can be more streamlined compared to some traditional methods. Secondly, it reduces investment as it may not require the construction of elaborate and expensive launching infrastructure. Thirdly, its flexibility allows for more diverse launching scenarios, adapting to different ship sizes and shapes. Finally, safety is enhanced as the airbags can cushion the forces during the launching process.
Material
Rubber formula suitable for air bag products
Our company has 30 years rubber formulator, according to the season, humidity adjustment formula. Summer will increase the specific gravity of materials such as carbon black and maintain the hardness and wear resistance of the air bag. The rubber properties are tested once each time the formula is adjusted, and the rubber properties are tested once every 7 days when the formula is unchanged.
The rubber performance exceeds the international standard 20%
The air bag is made of high quality rubber, which can increase the wear resistance and improve the service life. Our company produces air bags, the basic service life of 15 years.
The balloon wall is pressurized to become a whole
The air bag is pressurized after forming, so that the sheet becomes whole. Vulcanization process using high pressure vulcanization temperature difference < 2℃. Our company promises never to use low temperature and low pressure vulcanization process.
Require full inspection of the factory
The inspection area of our company can test 20 airbags of 20 meters in length at the same time, and require full inspection of the factory, once the problem is detected, it will be repaired or re-produced. Export air bag quality problems, long transportation cycle, high cost, the impression of the project, our company strictly implement the "quality problems in the factory to solve the concept."
Structure And End Fittings
Rubber airbags are cylindrical balloon body, with two conical head and end mouth. Swivels and air inlet kits are screwed with end mouth.

Type and Model
Marine Launching Pneumatic Airbags: Types and Models
Ship Launching airbags are classified into three types based on their bearing capacity per meter in length. To determine the Safety Working Pressure, we specify the number of layers, referring to the number of Synthetic - tyre - cord layers. Additionally, we can provide other types upon clients' requests.
QP - Ordinary Airbag
The QP series represents the ordinary airbags. These airbags are constructed with 3, 4, or 5 cord fabric layers. They are suitable for applications where the required bearing capacity is relatively moderate. These airbags can handle a certain level of load during ship launching operations and are a cost - effective option for projects with less demanding requirements.
QG - High - Bearing Capacity Airbag
The QG series consists of high - bearing capacity airbags. These are made with 6, 7, or 8 layers of cord fabric. The increased number of layers enhances the strength and durability of the airbags, enabling them to withstand higher pressures and heavier loads. They are ideal for larger vessels or more complex ship launching scenarios where a greater bearing capacity is needed to ensure a smooth and safe launch.
QS - Superhigh - Bearing Capacity Airbag
The QS series is designed for superhigh - bearing capacity requirements. These airbags feature 9, 10, or more layers of cord fabrics. With this substantial number of layers, they can handle extremely heavy loads and are typically used for launching very large ships or in situations where the forces involved during the launch are substantial. This series offers the highest level of performance and reliability for the most challenging marine launching projects.

Marine Launching Pneumatic Airbags Performance: Air Bags Lifting Capacity Principle
The bearing capacity of ship - launching airbags is calculated based on the working pressure and contact area. The working pressure is determined from the burst pressure and the safety working factor.
Due to the flexibility of the rubber airbag, the contact area can be influenced by several factors. These include the condition of the ship being carried and the different positions relative to the center of gravity during the ship launching and landing processes. As a result, the bearing capacity of the rubber airbags will also vary in accordance with the changes in the contact area.
