Ship Launching Marine Landing Airbags Synthetic Tyre Cord Rubber Layers

Synthetic Tyre Cord Rubber Layers Marine Landing Ship Launching Airbags

The airbag is featured with energy conservation and environment protection, reasonable structure and durability. The airbag body is round and smooth and the heads are safe and reliable. Our airbags have been widely used domestically and overseas. The application of airbag has little specific site constraints and it does not large machinery or equipment, thus using airbags to launch or land ships can shorten project period and financially save a large amount.

Flexible balloon like an elastic cushion, it make the hull in the process of launching free pitch, keep the bottom has a larger contact area, makes the stress of the hull very ease, so that the hull structure, on the surface of the paint (coating) will not be damage. LuHang ship launching airbag is specially designed for launching technology development, the main function is carrying or pulling the ship launching uphill, has a very high load capacity, wear resistance and corrosion resistance to seawater.

Outer Rubber Layer

The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.

Inner Rubber Layer

The inner rubber layer seals pressurized air inside marine airbags.

Synthetic-Tire-Cord Layer as Reinforcement

The reinforcement cord layers, which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement.

Performance of Airbags

The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.Because of the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.

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.
