6 Layers Natural Rubber Heavy Duty Air Bags Standard No Leakage In 24 Hours

Dia 1.2m x Length 10m x 6Layers Natural Rubber Heavy Lifting Boat Launching Marine Airbags

LUHANG Marine Rubber Airbags are also called ship launching airbags,boat lifiting air bags,sunken ship salvage airbags,heavy moving airbags,inflatable Rubber airbags.

1. LUHANG Marine Rubber Airbag Application

· 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)

· Mobilisation of heavy structures on land (a suitable alternative to transporters)

3. Raw Materials

Ideally, airbags should be made of new rubber material that adheres to the following standards:

• ISO34-1 Tear Strength ≥400 N/cm
• ISO37 Tensile Strength ≥18 MPa, Elongation at Break ≥400%
• ISO1761-1 Hardness (Shore A) 60±10°
• ISO815-1 Compression Set
• ISO188 Requirements After Thermal Aging
• ISO1431-1 After Static Ozone Ageing

The keyword here is new.LUHANG NEVER uses recycled or reclaimed rubber material in airbag production. This is a huge red flag. Quality rubber makes the foundation of the whole “inflatable roller” idea, especially when it has to bear very high values of weight on top. Recycled and reclaimed rubber have substantially lower elasticity and has a very fast ageing rate which compromises the integrity of airbags. Use these recycled rubber airbags a couple of times and you will realise they burst very easily.

On the other hand, cords play a big role, too. These “two cords” are supposed to be two-strand cords with more than 205 N strength per cord. Some manufacturers, like LUHANG, procure and use a higher strength cord (above required standard) to ensure quality strength; but some other suppliers use two-strand cords with lower strength sometimes. There is also the difference with other cords like dacron cords etc. The difference in use of raw materials can have a cost difference of more than 65%!!

Raw materials in airbags are sometimes very different from one another, and hard to detect.

4. LUHANG Marine Rubber Airbag Structure

1) 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.

2) Inner Rubber Layer

The inner rubber layer seals pressurized air inside marine airbags.

3) 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.

7. Company Introduction

Qingdao LuHang Marine Airbag and Fender Co., LTD,

founded in 1988, is the leading & professional & largest marine airbag and fender manufacturer in China. We have established long-term cooperation relationship with central enterprises, many big shipyards and ship owners, trading companies in China. We also export to Malaysia, Indonesia, Philippines, Singapore, India,Vietnam, Turkey,Italy,USA, etc. and many other countries in the world.

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.
