ISO 17357 Standard Ship Fender And Yokohama Pneumatic Rubber Fender
Pneumatic rubber fender is a device for berthing, buffering and
protection of ships. It uses compressed air as a buffer medium to
prevent ships from colliding when berthing. Inflatable rubber
fenders are more economical and more durable than ordinary rubber
fenders, so they are more popular and widely used. It is the first
choice of many armies.
Yokohama fender is a leading anti-collision device for maritime
applications in the world today. It has become an ideal ship
protection medium and has been widely used by large oil tankers,
LPG ships, offshore platforms, large docks, ports and docks.
The structure of Rubber Pneumatic Fenders:
The outer rubber layer protects the cord layer and inner layer from
abrasion and other external forces. This compound has sufficient
tensile and tear strength to withstand any weather condition and
hard usage
The cord layers are arranged at ideal angles to hold the internal
pressure and to distribute the stress evenly. The fenders cord
layer is constructed by means of integrative twine technology and
consists of polyamide fiber with high tensile stress, so that the
fenders have unique strength and uniformity in different
directions.
The inner rubber layer seals the air inside, utilizing a compound
with airtight quality.Pneumatic Rubber fender description Yokohama
rubber fender is intended to be used for the berthing and mooring
of a ship to another ship or berthing structure. It also specifies
the test and inspection procedures for high-pressure floating
Pneumatic Rubber Fender.
Flange opening:The metal parts at both ends of fender,to which an
air valve or safety valve can be adapted.
NOTES OF PNEUMATIC RUBBER FENDERS
1 Keep the fender away from sharp objects, in case damage the
fender body.
2 Fender cannot touch with acid, oil and other organic solvent.
3 When fender not use for a long time, they should be washed to
clean, dried and proper compressed air inflated. Put them in a dry
, cool and ventilated area.
4 The storage area should be far away from heat source.
5 Do not put heavy objects on the fender when fender not in use.
6 Fender in normal usages should be checked the inner pressure
every 3 months. Meanwhile, Air valve core should be replaced every
6 months.
