Natural Rubber Pneumatic Marine Fender Durable 0.05MPa And 0.08MPa
For Pier And Vessels
What type do we have?
Tire net type: multiple tires are tied to the ball, and both ends are tied to a
special flywheel that can rotate flexibly. Suitable for large and
reliable balls.
Rubber net type: tie a special rubber pad to the ball, which can be freely
contracted or stretched when squeezed. Suitable for medium and
small reliable balls.
Line type: The net cover is woven with nylon rope; tightly tied to the ball.
It is suitable for small size reliable balls.
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.

About the quality:
1. With ISO17357 DNV - GL inspection, CCS inspection (Rubber
Material Testing, Product Size Testing, Air Tightness Testing,
Pressure Testing)
2. The factory quality inspection report issued by Henger, and if
the customer needs it, a video inspection certificate can be issued
when the product quality inspection is performed before the product
leaves the factory. On the premise that the buyer bears the cost, a
third-party testing agency can be invited to conduct product
testing.
About the production process:
1. After the fender is produced, it will stand still for 48 hours
in strict accordance with the requirements to check the product
quality.
2. Before leaving the factory, each product will be strictly tested
for air tightness, and a dedicated technician will use soapy water
to detect air leakage. Once there is a quality problem, it is
absolutely not allowed to leave the factory and sell it.
