Marine Rubber Airbags

The wear-resistant marine rubber airbags manufactured by Aorunda are produced with a compound formula of high-quality natural rubber and styrene-butadiene rubber, with a rubber content of over 50%. Reinforced with high-grade nylon dipped cord fabric as the skeleton—boasting a single filament breaking strength of 313.6 N—they are formed via the integral winding process and high-temperature vulcanization, delivering a tensile strength of more than 20 MPa. Their wear resistance, aging resistance and tear resistance all far exceed the industry standards.

Product usage scenarios

Wear resistant rubber airbags for ships are practical "multi scenario experts": they are placed at the bottom of small and medium-sized fishing boats and yachts in shipyards, and can be inflated for 15 minutes to smoothly lift the ship and move it to the land rack, which is 30% more efficient than traditional slipways; During offshore stranded rescue operations, 2-3 airbags can lift hundreds of tons of the ship's hull, allowing the tugboat to easily carry away sediment; The salvaging of sunken ships can support the stable floating of the wreckage, and when transporting large ship equipment in short distances at the dock, it can also replace heavy lifting equipment for flexible transportation, almost covering the entire chain of shipping operations.

The shape of the airbag is tailor-made for the job: a long cylinder with a streamlined structure with two conical ends, perfectly fitting the curvature of the ship, and uniformly subjected to force without slipping; The surface layer is made of high wear-resistant rubber composite layer, reinforced with mixed woven curtain fabric for support. Even if it scratches the edges and reefs of the shipyard, its service life is twice as long as ordinary airbags. It also supports customization with a diameter of 1-3 meters and a length of 10-30 meters, suitable for ships of different tonnages. In terms of appearance and color, the classic black matte rubber is resistant to dirt and easy to maintain. The anti scratch texture on the surface not only enhances friction but also reduces wear. It can withstand sea wind erosion for more than 3 years even when stored outdoors for a long time without additional protective maintenance.

Production advantage

Marine rubber airbags undergo aging resistance and tensile strength testing upon entry of rubber raw materials. Temperature and pressure parameters are recorded for each vulcanization process during production, and a full inspection is conducted before leaving the factory to ensure "120% rated load inflation and pressure bearing"; We hold CCS certification from the classification society and ISO9001 quality system certification. Each batch of goods comes with an exclusive inspection report, and the quality can be traced throughout the entire process.

Core strengths

1. The durability is leading. The outer layer is made of neoprene+double polyester cord fabric composite structure, and its wear resistance and aging resistance are twice as strong as those of ordinary air bags. It can still be used stably for more than 3 years under the sea breeze and rocks, reducing the replacement frequency;

2. Its adaptability is more flexible and supports customization. For example, in tidal flat operations, additional mud-proof and abrasion-resistant layers can be added. Most similar products have fixed specifications;

3. It has lower implicit costs. The inner wall of the airbag is coated with an anti-seepage layer, and the air pressure loss rate after inflation is 50% lower than the industry average. It does not require frequent air supply, saving labor and time costs for operation. Its long-term cost-effectiveness far exceeds similar products.

Special attentions during the use of the airbag

1. Control the working pressure strictly and it's not allowed to exceed the working pressure

2. There shall be no sharp and protruding hard object on the contact surface with the airbag in case it punctures the skin of the airbag

3. Try to avoid distortion happened to the length direction of the airbag

4. Empty charge test shall be performed if the air bag is not used for a long time or reused after repair. Charge pressure if the airbag shall be the same as the test pressure valve when delivered. Inspectors shall be at least 3 meters away from the air bag. For air bag recovered from large airbag damage, its working pressure shall be reduced airbag to reasonably. Besides, annual check shall be conducted on air bag which are used often

5. Not long after the repair or airbag before revived, shall be carried out before reactivated no-load charging test.Test pressure should take the pressure of work.Lab, inspector shall at least 3 meters away from the airbag.If after the repair demaged area, should reduce pressure of work. Every year, all common the experiment, can ensure a safe use.
