Pneumatic 50 fender size and performance requirements

1. Pneumatic Rubber Fender Introduction

What is Pneumatic Rubber Fender?

The "Yokohama Type Pneumatic Rubber Fender" was developed in . Progress in the development of such floating pneumatic rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures. Floating pneumatic fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today, more than millions of fenders have been supplied worldwide both for ship-to-ship and ship-to-dock (STD) operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring

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.

5. Pneumatic Rubber Fender Application

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.

6. Pneumatic Rubber Fender Transportation

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.

7. Pneumatic Rubber Fender storage

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.

8. After-sale service

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.
