Pneumatic fenders is a leading anti-collision device for marine application in the world today. This compressed air rubber fender is used as a protective medium. Therefore, pneumatic rubber fenders serves as a protective medium against collision when ship-to-ship contact (STS) and ship-to-berthing (STB). Pneumatic fenders has the advantages of massive energy absorption with low unit surface pressure acted upon the ship. So penumatic fenders has become an ideal ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbor and wharfs.
Core attributes
Pneumatic fenders have any advantages including:
Easy and fast to deploy
Very low reaction and hull pressure
Performance adjustable by varying initial pressure
Suitable for areas with large or small tides
Maintains large clearances between hull and structure
Optional chain-tyre nets for heavy duty applications
Low maintenance
Optional chain & tyres for heavy duty use
Application:
Pneumatic fenders are suitable for many applications including:
Tankers, Gas Carriers and Bulk Cargo Ships
Fast ferries and aluminum hulled vessels
Temporary of permanent installations
As stand-off fenders to realign ships with shore facilities
Performance
Pneumatic Fender Technical Performance Table(As followings)
Notes:
1. Guaranteed energy absorption represents the guaranteed energy absorption at 60% deflection.
2. Tolerance of reaction fore and deflection are as follows: Reaction: 10%, Deflection: 5%.
3. Each reaction and energy absorption is measured under static conditions.
4. Testing pressure rate indicates the testing pressure at the factory.
5. Weight of fender body and net may vary 10%.
6. Special sizes are available upon request.
7. Different levels of performance according to internal air pressure levels specified this fenders.
Testing and quality
Yutung is very focused on the quality of their product. Yutung have invested in the most equipment for testing in order to meet the customer'sdemands for high quality. Yutung's fenders are used by customers world wide and they
Have been tested under rough conditions both in warm and cold climate. The large amounts of satisfied customers are our best references.

Semi-automatic Saw Blade Pipe Cutting Machine
1. Gearbox:
The gearbox is made of casting, so it is very solid. At the same time, it is formed by the horizontal machining center for one-time processing and forming, that accumulated tolerance is small. The core component gear of the gearbox are imported from Taiwan, which is using advanced grinding and vacuum heat treatment technology, with high precision and long service life. In the use process, the noise of the machine head is small, the transmission efficiency is ensured, and the service life is long.
2. A self-lubricating bearing:
It is added at the movable joint between the head and the connecting seat, which can lubricate the connecting shaft in order to prevent the direct friction causing abrasion, so it helps to improve the working life, and accuracy that reduce the vibration of Saw Blade.
3. Regulating valve:
Regulating valve: the control valve imported from Taiwan is adopted, with high machining accuracy, stable flow control and even cutting speed. Fast return speed, improve work efficiency.
