ISO 17357 Standard Mooring Pneumatic Rubber Fender Yokohama Type

ISO 17357 Standard Yokohama Type Mooring Pneumatic Rubber Fender

1. Pneumatic rubber fender introduction

♦ Definition:  

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.

♦ 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.

♦ Characteristic:  

● External wear resistance

● Bearing pressure

● Ageing resistance

● Long service life

● Easy storage

● Non deformation

● Simple installation

♦ Functions & Applications

● Installed on the wharf and dock for berthing

● Installed on the shipboard for berthing

● Float chamber

● For moving the cargo

● Pipe seal

5. Company Introduction

Henger Shipping Company mainly produces pneumatic rubber fenders (marine ball) marine airbags, , marine navigation marks, mooring buoys, bridge anti-collision piers, rotating guardrails and inflatable mandrels for construction projects. They are constantly updated and improved every year. Owning a professional production line developed by ourselves, the products are exported to domestic and foreign markets, advanced mechanical equipment and technical processes, produce high-quality airbags with abrasion resistance, aging resistance, good air tightness, high strength, long service life and high bearing pressure The airbag has now undertaken safe launching and launching projects for giant ships with a load of 60,000 tons and a dead weight of more than 10,000 tons. At the same time, it overcomes the disadvantages of being restricted by fixed launching slides when repairing and building ships. The advantages of high comprehensive economic benefits. The airbag is widely used in the upper row and launching of various ships, as well as salvaging sunken ships and moving heavy objects. The launch of high-strength dual-purpose airbag products has solved the common problems of launching and launching water in various types of flat, sharp-bottomed, medium and small ships at home and abroad.
