1. Pneumatic Rubber Fender Introduction
1 Outer rubber
The outer rubber layers that covers the outside of fender protects the cord layers and the inner rubber from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black, but other colors are available on request.
2 Inner rubber
The liner of a rubber membrane seals the pressurized air inside the fenders.
3 Synthetic tire cord layers for reinforcement
The reinforcement layers, which are made of synthetic tire cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.
4 Beading ring
A steel ring is placed at one end (or both ends) of the fender and holds the end of cord layers.
5 Flange
A steel flange is mounted on the fender, to which an air valve or safety valve can be adapted.
6 Safety valve
Fenders of diameter 2500mm and larger shall be equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. Fender which are smaller than 2500mm in diameter, can be equipped with a safety valve if required.
7 Metal accessories
All the relevant metal accessories of pneumatic fenders, include shackles, towing rings, swivels, chain net, are made of stainless steel, which are resistant for sea water corrosion.

Unique Design of Henger Pneumatic Rubber Fender
Active-Protecting Safety Valve , All fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.
It is a patented design which could avoid explosion of fenders from collision and air inflation.
Henger Flange is casting of corrosion-resistant iron with galvanized anti-corrosive coating, which will strongly prolong the fender quality and service life. The strength of Henger casting flange improves 40% higher than traditional type.
1 Safety and Reliability
Henger Pneumatic Rubber Fenders are constructed of natural rubber, several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation.
2 Patented Active Protecting Safety Valve Design
All Henger Pneumatic Rubber Fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure.
3 No Deterioration or Variation in Performance
Henger Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore performance deterioration due to fatigue is absent.
4 Advantages at Inclined Berthing
Henger Pneumatic Rubber Fenders, energy absorption does not decrease at inclined compression up to 15 degrees.
The are two typical installation type: ship to ship operation and ship to dock operation.
a. ship to ship operation
Generally speaking, two contact points are enough for the light duty ship to ship operation. But 1 or 2 extra pneumatic rubber fender should be used as the primary fender to absorb the berthing energy for the heavy duty ship to ship operation, and keep proper stand-off distance between two ships. Meanwhile, two or more small-size fenders can be hung on the ship hull as the secondary fender.
b. ship to dock operation
Pneumatic fenders are often used for the ship to quay operation because of its excellent performance. The pneumatic fenders are anchored with quay by the guy chain and shackles. Meanwhile, the pneumatic fender can be floated on the water surface depend on the change of tide.
Transportation We can take the deflation pallet transportation and the entire fender transportation without deflation according to the requirements of customers. We always put the customer's requirements first.
1. When the Pneumatic rubber fender is not used for a long time, it should be washed and dried, filled with appropriate compressed air, placed in a dry, cool, ventilated place.Inventory temperature is maintained at -15 ℃ -40 ℃ .
2 .The place where the fender is stored should be kept away from the heat source.
3 .Fenders shall not be in contact with acids, alkalis, greases and organic solvents.
4 .When the fenders are not in use, they must not be stacked and should not be stacked on the ba. In order to better extend the service life of pneumatic rubber fenders, it is recommended that you store them in strict accordance with the above recommendations.
The product warranty period of Henger is 24 months, and the average supplier can not reach such a long time, which is also the trust we and customers have in our factory products.
