Rubber Inflatable Fenders Or Pneumatic Fenders China Factory

Rubber inflatable fenders have been widely applied in scenarios such as oil tankers, container ships, yachts, offshore platforms, large shipyards, military port terminals, and large bridge piers.

According to ISO 17357:2002 Ships and Marine Technology - High-Pressure Floating Inflatable Rubber Fenders, fenders mainly consist of the following components:

Outer rubber layer: A rubber layer covering the exterior of the fender, designed to protect the skeleton material and inner rubber layer from external damage or wear

Inner rubber layer: A rubber layer on the inner wall of the fender, which prevents gas leakage and maintains the air pressure inside the fender.

Cord fabric layer: Composed of rubber-coated cord fabric, serving as the skeleton material of the fender.

Coil ring: A steel ring placed at one (or both) end(s) of the fender, used to fix the ends of the cord fabric layer.

End flanges: Metal components at both ends of the fender, where inflation valves and safety valves can be installed.

Fenders offer the following notable advantages:

High impact energy absorption capacity with low counter-impact force on ships;

Simple installation process;

Excellent elasticity, resistant to deformation under compression;

Lightweight, economical, and practical;

Stable performance under inclined compression.

Inflatable rubber fenders use compressed air as a buffer medium to absorb ship impact energy, making the ship berthing process more flexible and cushioned, thus effectively achieving collision prevention. They are widely used in ship-to-ship transfer operations and ship berthing operations.

The sheathed inflatable rubber fender is a high-strength and high-wear-resistant fender system developed in accordance with ISO 17357 (Net Type Pneumatic Fenders), with dimensions ranging from D1.0m×L1.5 to D3.3m×L6.5m. Its distinct appearance feature is that the main body of the inflatable fender is wrapped with a tire chain mesh, significantly extending the service life of the fender body. The tires used are all specially treated for a better surface appearance, and the chains are fully hot-dip galvanized for strong resistance to seawater corrosion.

Fenders, also known as marine fenders or dock fenders, are elastic cushioning devices installed on the edges of ships or docks. Their main function is to mitigate the impact force when ships berth, moor, or when contact occurs between ships, thereby avoiding or reducing damage to ships, docks, and other facilities. There are various types of fenders. Classified by material, they include wooden, steel, rubber fenders, etc. Among them, rubber fenders are the most widely used due to their good elasticity, wear resistance, and corrosion resistance. In terms of structure and function, rubber fenders can be divided into solid rubber fenders (non-floating type) and floating rubber fenders: Solid rubber fenders include various types such as D-type, conical, drum-type, and fan-type. They have a simple structure and good energy absorption performance, and are suitable for various dock and ship scenarios. Floating rubber fenders (such as inflatable and filled types) can float with changes in water level, featuring large compression deformation and low reaction force, which makes them suitable for areas with large tidal changes or ship-to-ship operation scenarios. The performance of fenders is mainly affected by factors such as material quality, design structure, and size specifications. Their reasonable selection is crucial for ensuring the safety of ships and port facilities.
