Hydropneumatic Fender For Submarine Natural Rubber With High Energy Absorption
Hydropneumatic Fender
Hydropneumatic fender is used in catamarans, semi-submersible platforms, and drilling rigs for a long time. This hydro-pneumatic 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.
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 hydropneumatic fender supplies with a variety of specifications and dimensions to meet customer’s requests and different application conditions.
Hydropneumatic Fender Advantage
1. Light weight, high compression deformation, low reaction strength, and high energy absorption.
2. Good floating performance, can meet the needs of water level changes.
3. Using compressed air as the medium, the energy consumption of the collision may not be compressed air.
4. Easy to install and long service life
Hydropneumatic Fender Structure
① Outer rubber layer
Hydropneumatic fenders are covered by the outer layer made of natural rubber. This rubber compound is strong enough to protect the inner layer and synthetic-cord layer from the damage of external forces and severe weather conditions due to its high elasticity and abrasion resistance.
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 designed to seal the air inside the fender.
