50kPa 80kPa Cylindrical Inflatable Hydropneumatic Fender
Inflatable Hydropneumatic Fender
Inflatable hydropneumatic fender is used in catamarans, semi-submersible platforms, and drilling rigs for a long time. This inflatable hydropneumatic fender is filled with water and air inside to make it vertically installed against submerged hulls with a counterweight. It’s always regarded as a buffer to reduce shock in between due to its excellent performance of great elasticity and abrasion-resistance.
Inflatable hydropneumatic fenders are made of natural rubber and tire cord reinforcement in the shape of cylindrical, which is strong enough to withstand external forces and severe weather conditions.
Fully compliant with the ISO17357 standard, Jerryborg’s inflatable hydropneumatic fender supplies with a variety of specifications and dimensions to meet customer’s requests and different application conditions.
Inflatable Hydropneumatic Fender Structure
① Outer rubber layer
Inflatable hydropneumatic fenders are covered by the outer layer made of natural rubber. The outer rubber layer uses special compounds that provide additional tensile strength and tear strength to protect the fender from severe weather conditions and frequent use.
② Synthetic-tire-cord layer
The Synthetic-tire-cord layer is made of synthetic-tire-cord fabrics, compared with synthetic canvas fabric and synthetic belt fabric, this reinforcement layer performs better in fatigue-resistance and pressure-holding.
③ Inner rubber layer
The inner rubber layer is specially designed to seal the internal air and prevent any leakage, just like the inner tube of a tire.
