fenders for boat rubber pneuamtic floating fenders with 50KPa / 80KPa
Major Strengths Of Our fenders for boat rubber pneuamtic floating fenders:
High safety level: our pneumatic fenders can stand the maximum pressure up to 4 times that of the operating pressure.
Easy maintenance: our fenders just need inflation once every six months.
Low transportation cost: our fenders can be deflated and folded for transportation, thus saving about two thirds of the transportation cost.
Long lifespan: it is guaranteed that our fenders can be used for over 10 years under normal conditions.
Nanhai airbag manufactures yokohama fender with our airbag technology in compliance with ISO 17357-2002 standards. Our yokohama fenders are ideal for permanent and semi-permanent port applications as well as for offshore ship-to-ship transfers, being fast and easy to deploy and providing reliable protection to vessels.

Yokohama Fender Description:
Yokohama pneumatic Fenders which is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorber between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water.
The yokohama fenders are kind of a cylindrical air-bag with hemispherical heads at both end. Basic body construction of this fender consists of an outer rubber layer, cord layers and inner rubber layer. All of these are vulcanized together. End flanges are at both end for convenience of air charge and other purposes.

Ship to Ship applications
After selection of the correct size fender suitable for the combined energy of the two vessels, the fenders should be equally spaced along the length of the smallest vessel. At each end it is recommended that a smaller secondary fender is installed to protect against rolling due to swell and wind during transfer operations. The fenders can be slung individually from mooring points along the deck or all linked together in a line fastened only at each end of the vessel.
The structure of Pneumatic Fender:
1. The outer rubber
Outside on the ball of rubber layer, which is used to protect by skeleton material and lining rubber ball from external force damage or wear.
2. Cord fabric reinforcement layer
Reinforcement layer is winded by nylon cord layer and it maintains the inner pressure of fender.
3. The inner rubber
On the ball inside the rubber layer, which is used to prevent gas leakage and stay on the ball pressure.
4. The end of the flange
On the ball at the ends of the metal parts, can be installed charging valve and relief valve.
Yokohama Fender Specifications:
Yokohama Fender utilizes compressed air as cushion medium to take in the impact energy of ship. It features favorableflexibility, powerful energy absorption,portability (lightweight) and so on,and its angular compression performance is notliable to degrade.Thus, it is widely used to help ships lighter or moor in open sea or wharf with poor berthing conditions.
