Xincheng Factory Sling Type Marine Pneumatic Rubber Fender for Ships
The Advantages of Pneumatic rubber fenders:
1 Safe for excess load.
The reaction force of floating fenders does not increase sharply even under excess load. Therefore, these fenders perform extremely well under such conditions and, as a result, protect ships and mooring facilities.
2 No deterioration or Variation in performance
Because pneumatic fenders use the compressive elasticity of air, there is no performance deterioration due to fatigue. The performance of these fenders remains unchanged at extremely low temperatures, even below -50℃.
3 Safety and reliability
Pneumatic rubber fenders are constructed using several layers of strong type cord and are therefore extremely resistant to pressure and cutting. The larger sizes (2.5m dia upward) are fitted with a safety valve to prevent accidents in event of over compression.
4 Simply and low cost installation
The weight of the fender is supported by the water on which it floats. Fenders can, therefore, be moored simply by means of a guy rope or chain at minimal cost. They can be removed easily to another position when not in use and transferred to alternative mooring points as required.
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.
