D1.6m x EL12m x 6layers Ship Launching and Docking Rubber Airbags

1. Layer Quantity Overstatement

Imagine the shock when we encountered some customers came to us asking for a 15-layer airbag!

Most ships/structures can be handled with our 7-layer type airbags, or in some cases (sharp hull or challenging work conditions) maybe up 10 layers. But anything more than 10 is definitely not necessary. These overstatements cause industry-wide confusion, and buyers thought they are getting more with these cheap prices. However, we are convinced our LUHANG 7-layer type airbags would perform better than many of those “15-layer” airbags. Truly reputable suppliers will understand that these high layer counts mean nothing. For those “15-layer” claims, how many layers do you think you are getting?

Also, quantity is not everything. It is vital for the buyers to educate themselves of the difference in quality. And the best part is to try our products to see the difference for themselves!

Fact : Find a trusted manufacturer who does not over-promise and under-deliver.

2. Fabrication Technology

Given all the materials are constant, do you think the end product will be the same? That is not actually the case. Even if both makers are using the same type of materials, the technology and expertise in production would set them apart. It is important for a manufacturer to suitably use certain types of automation and machines to standardise certain procedures, ensuring a very consistent output which minimises mistakes and errors. Skilful workers (and NOT general workers) are needed. With much experience, these personnel are the ones who will make sure every step is according to standard and will result in a consistent, high quality airbag. Details like the alignment, tightness and strength of parts should be inspected closely.

At LUHANG, we practise a new innovative fabrication technology. This practice enables us to fabricate rubber marine airbags in a more consistent manner, enhancing strength by having multi-directional overlapping layers and minimise human errors.

In addition, we have highly qualified vulcanisation experts. When it comes to manufacturing these high pressure airbags, vulcanisation is a key process where over-vulcanisation or under-vulcanisation can bring very large performance differences!

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.
