With Tyres Annd Chain Rubber Fenders For Boats , 50type Rubber Bumper
Pneumatic Fenders are suppiled with two different inside pressure levels to cover a wide performance range.
Pneumatic Fenders are available in diameters ranging from 300 mm to 4,500 mm and lengths ranging from 500 mm to 9,000 mm, as well as special sizes. All sizes are available as sling-type or with a heavy duty chain & tire net
The Pneumatic rubber fender also be certified by CCS, DNV, ABS, SGS and BV.
ISO Standard
All Xincheng Marine Systems pneumatic rubber fenders are manufactured and 3rd party certified in compliance with
ISO 17357:2002. The stringent requirements of this standard ensure that fenders are of a high quality and can withstand the rigorous environments and applications they are designed to operate in. ISO 17357:2002 details three major elements of construction: the outer rubber, tyre-cord reinforcing layer and the inner rubber.
Outer Rubber
The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.
The diagram below shows the actual properties as specified in ISO 17357. Generally, the outer rubber is black, but other colours such as grey and off-white can be supplied upon request.
Tyre-cord Layer
Synthetic tyre-cord layers have proven to be the best option for
strong, efficient reinforcement for pneumatic rubber fenders. Each
layer is coated with a rubber compound on both sides that prevents
contact between the layers, reducing friction and
wear during bending, compression and stretching. The same compound
isolates each thread within the layer.
This greatly improves the ability of the fender to hold pressure,
fatigue resistance and endurance life. Other reinforcing layer
materials such as canvas have wear points that significantly reduce
the life off the fender.
Inner Rubber
The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.
