Inflatable Marine Rubber Airbag For Global Marke
Introduction
LUHANG Rubber airbag is composed of inner rubber board layer, multi-layer nylon cord reinforced rubber plate and outer rubber layer. With good air tightness and flexibility,supply moderate force to keep ship stable and not be damaged when ship launching.Luhang rubber airbags are designed for higher load capacity,wear resistance and Seawater corrosiond resistance.Luhang rubber airbags are not only just used for Ship launching &docking, but also be widely used for Salvage operations,Transfer heavy structure,Storage and transport some Gas or liquid,Erection of bridge and Water pipe Floating.
The Sturcture Of The Airbag
1.Skeleton materials: Nylon "6" Rubber curtain
Density: 90 thread/10cm (width)
Fracture strength: 206KN/thread; 294KN/thread
2. Airbag entrance: Cast steel, Inner pipe threaded M46*2
Marine Airbag For Ship Launching Technology
Marine airbag for ship launching technology developed on the basis of the traditional launching, use flexible airbag instead of the slide. It overcome many disadvantages of traditional launching: Flexible airbag like an Elastic cushion, It makes the hull free pitching in the process of Ship launching Keep the bottom has a larger contact area, Enable hull's stress is very moderate, So that the paint on the surface and the hull structure will be not damaged.LuHang ship launching airbag is specially designed for launching technology development, Main function is: ship launching and landing, heavy moving, salvage sunken ship, has a very high load capacity, wear resistance, corrosion resistance to seawater.Ship air bag launching technology is invented in the early 1980 s, has a complete independent intellectual property rights of technology in China, after thirty years of improvement and development, has now been ten ton vessels ability in the water. Marine airbag for ship launching technology compared with traditional launching technology, has the following advantages: Save the investment of the basic construction of the shipyard, in the basic construction of shipyard, water facilities, such as the traditional launching way and underwater engineering investment is astonishing. The air bag launching technology of shipyard, only need to build simple ramp, facilities is simple and without complex underwater engineering, save the basic investment of the construction of the shipyard.
Airbags Specifications And Main Performance
Luhang The new integrated Marine high strength gasbag is divided into fivetypes:LH-4,LH-5,LH-6,LH-7,LH-8
1.Distinguished by diameter
The dia selected mainly according to the height of the dolphin. Normally the airbag diameter should be 0.5-0.7m bigger than the dolphin height, otherwise the airbag can't hold up the ship.Airbags, less than 1.2 mm in diameter, can only be used for little boat launching. ten thousand tons of ship launching need 1.5 m or 1.8 m.when the block height is not more than 0.9m,choose the 1.5m dia airbag. Choose 1.8m airbag when the block height is bigger than 1m.
2.Distinguished by the bearing capacity
3. The bearing capacity
Airbag is flexible,the shape will changed when using.So The bearing area and capacity are changed.
The bearing capacity:
F=PS
P= The pressure in the airbag
S= Bottom and airbag contact area
S=0.5*(D1-D2)
D1: the height when full of gas
D2: the height after compression
Quality Assurance
Quality assuranceProducts comply with quality requirements of CB/T3795-1996
Technical Service And Support
We would like provide technical service and support for customers who use our airbags, including air bag launching project contracting, air bag launching plan formulation, design special air bag launching slipway and ramps.Large ships launching must develop the most appropriate for shipyard specific conditions, the security technology solutions, because the shipyard water environment is different. Technical team and the successful experience is important basic.
