High Performance Wear - Resistant Recycled Marine Salvage Air Lift Bags

D1.8 m x L15m x 7layers Hauling out of large marine structures Air Bag

LUHANG marine rubber airbags are commonly used for projects in the heavy industry and marine shipbuilding sector.

Some of their most common uses are as follows:

• Launching of 250-ton to 10,000-ton ships or boats. Sometimes even more
• Launching of heavy large structures up to 10,000-tons
• Hauling out of large marine structures including ships for repairs or recycle
• Providing additional buoyancy for marine salvage projects or flotation needs (reducing draft of barges etc)
• Moving heavy structures on land (a suitable alternative to transporters)

The usage of marine airbags are especially common in the shipbuilding space. However, there has been a misconception in the product, as well as large differences in pricing available in the market. In fact, many of the suppliers claim they are providing xx amount of layers, xx amount of weight etc to justify that their product quality is the same as many of the trusted manufacturers’ products. The vast differences in prices manage to confuse many of these airbag buyers. So, what are the “promises” usually made that a buyer should be careful of?

Marine Airbag Specification

• The standard specification of marine airbags.

You can choose the required diameter and effective length to meet your projects.

★ Diameter (D): from 0.5m to 5.0m.

★ Effective Length (EL): from 5m to 30m.

★ Total Length (TL): from 6m to 32m

The above specifications only are our standard specifications arrange. Can be supplied customized size upon customers’ request.

• The standard number of layers

The number of layers, which mean the number of Synthetic-tyre-cord layer, usually, our airbags contain 3,4, 5, 6, 7, 8, 9,10 layers types. Other type is still available upon your request to confirm the Safety Working Pressure.

LUHANG Marine Rubber Airbags Advantages

• High precision engineering using 2 or 3 -strand cords with great tensile strength.
• Made from NEW industry leading quality rubber.
• Assurance of true number of layers.
• High-performance quality and above-industry-standard layer thickness.
• Quality detailing jobs, Ex: air valve length, ends’ extra layering, tighter connection with minimal failure etc. These areas are often neglected but extremely important to ensure your safety and maximise your return by prolonging useful life.

Marine rubber airbags use matters needing attention

a. Working pressure control in our safe working pressure.

b. Avoid contact with sharp objects

c. when Long time not need , should wash to dry , placed in a cool dry ventilated place . Storage place away from heat , acid and alkali , oil and grease

Third Party Inspection

Third party inspection is great. Our company happily offers third party inspection certificates from various inspection parties upon customer’s request.As we have mentioned earlier, it is a combination of the finest raw materials and skilful fabrication expertise that makes a product great. The fabrication skill can’t be “inspected” and compared on a newly made product. Besides, some manufacturers like LUHANG even go above and beyond the guidelines to use much higher grade materials in our products.

A more specific example would be product lifespan: product A and product B might work the same for the first two uses, but gradually, you will realise product A degrades, loses its flexibility and strength faster; while product B maintains its performance, and has a much longer useful life. In the long term, you would save more by using product B, even if sometimes it cost a little more upfront.

Company Information

Qingdao Luhang Marine Airbag and Fender Company is the leading & professional & largest company that initiated airbags for ship launching in China from year of 1998. During 30 years’ development and experience in airbag production and ship launching, our ship launching airbags have become the most reliable. Since then, more cargo vessels, barges, chemical tankers, tugboats, AHTS vessels, floating docks, and even contstruction caissons have all been launched using our airbags. Aside from ship hauling & launching.

Initially established as Qingdao Luhang Marine Airbag Factory in 1988 and changed to Qingdao Luhang Marine Airbags and Fenders Co.,Ltd in 2011, Qingdao Luhang had been devoted itself to developing and manufacturing marine airbags and marine fenders for more than 2 decades.

The factory area is 56,000m² with building area of  21,000m². The company has registered capital of USD 3 million and fixed asset of USD1.2 billion. We have a full line of production equipment: rubber mixing machine, rubber roller machine, the China biggest vulcanization tanks, the biggest Press Inspection Machine, EVA foam processing machine, Foam shaping machines and SPUA spraying machine.

Through these years' development, we have full range of marine airbags and marine fenders:

Ship Launching Airbags for ship launching and docking in shipyards

Marine Salvage Airbags for salvaging sinked vessels or refloating objects from under water

Other Airbags for special usage

Pneumatic Rubber Marine Fenders for ships and docks berthing

Foam Filled Marine Fenders for ship and docks berthing

Fixed Dock Rubber Fenders for docks and wharfs

Marine Buoys

From the begginning we have been focusing on technological innovation. With a team of experienced technicans and engineers, we have developed some high tech marine products and got some petents. We have been approved as a supplier of Navy products. 

Quality is our life line. We provide service of “three guarantees” (returning, repairing and replacing) on all our products in case of any defects due to the problems of material,manufacturing, performance under conditions of normal operation and maintenance.
