Ship Dock Marine Rubber Fender Yokohama Pneumatic Rubber Fender

Pneumatic Rubber Fender Introduction

The pneumatic rubber fender uses compressed air as the buffer medium, which makes the ship have better anti-collision effect when it is near the ship or dock.

The fender can be divided into the version with sheath and the version without sheath according to the pictures. The sheath of the pneumatic rubber fender is generally made of truck tires. For customers with special requirements, we can also use aircraft tires. The sheath acts as a second layer of protection to better protect the sphere. It also effectively reduces the impact force caused by the collision.

Fender Structure

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.

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

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.

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.

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.
