Submarine Using Pneumatic Rubber Hydro Fender
Product Introduction:
Submarines and other vessels which contact fenders below waterline require a unique solution. The pneumatic rubber hydro fender are specially adapted to this application. The fender body is partially water-filled, then pressurised with air and ballasted to make it stand vertically, fender draft and performance can be tuned by altering the water: air ratio and inflation pressure.
Feature of Pneumatic Rubber Hydro Fender:
1. The performance can be adjusted by changing the air-water ratio
2. The required draft can be adjusted
3. Low hull pressure
4. Self-regulation when the tide changes
5. Low installation and maintenance costs

Notice Of Fender Application And Storage
1. The fender pressure should be kept in the standard pressure ,within the rate of ± 5% range.
2. Often check the pressure , when the pressure drops, Inflate the fender in time, so as not to affect the normal use of the fender.
3. When connecting the fender with a steel wire rope, the wire rope should be fitted with a rubber sleeve to avoid damage to the fender
4. Do not touch the fender surface with the the sharp objects , to prevent piercing the fender. If the fender's surface is damaged, it will affect the lifespan of the fender.
5. When the fender is in normal use, the fixing points should be firm, prevent the detachment and wash away the fender. Suspension of the rope and hook ring should be connected orderly , can’t be in a mess.
6. If the fender won’t be used in a long time , to clean the fender surface with fresh water, and place the fender in a dry, cool, ventilated place, without direct sunshine.
7. When the fender is stored for a long time, the pressure should be reduced and the fender should be placed far away from the heat source.
8. Because the fender is rubber product, should try to avoid the fireworks, not contact with acid, alkali, oil and other organic solution
9. When the fender is stored, it shall not be folded or stacked, and don’t stack other objects on the fender.
