Floating Marine Rubber Fender ISO Pneumatic Rubber Fender for Boat Dock Ship

Pneumatic Rubber Fender

The Pneumatic Rubber Fender is a core and universal equipment for collision prevention and protection of ships and ports. It achieves energy absorption and buffering through the elastic deformation of the internal compressed air. It is collectively referred to as a high-pressure inflatable anti-collision protective shield, featuring mainstream structures such as drum-shaped and cylindrical shapes. With high energy absorption efficiency, gentle reaction force, and excellent adaptability, it is widely used in various ship-to-shore docking and ship-to-ship berthing scenarios. It is an essential anti-collision protection facility for ports, marine engineering, and various types of ships, balancing professional protection and scene adaptability.

Product Description:

Material Advantages:
The entire series is formed through an integrated molding and vulcanization process, without any joint gaps. The overall structure is a multi-layer rubber composite + high-strength frame reinforcement. Its air tightness, structural strength, and impact resistance all meet international maritime standards and are suitable for harsh marine conditions:
Outer layer protection: Natural rubber / nitrile rubber composite material, with additives for UV resistance, aging resistance, and seawater corrosion resistance. The surface can be customized with wear-resistant patterns / anti-slip coatings. It is resistant to friction, tear-resistant, and can effectively prevent scratches and impacts from ship berthing.
Middle layer reinforcement: Multiple layers of high-strength polyester cord / nylon cord are wound axially / radially, and some large-sized products are equipped with steel wire rings for reinforcement. This significantly improves the tensile and bulge resistance of the protective planks, preventing structural deformation under high pressure.
Inner layer air tightness: High-purity butyl rubber, with excellent air tightness, which can maintain working pressure for a long time, reducing the frequency of daily air inflation and lowering maintenance costs.
Standard accessories: All specifications are equipped with galvanized / 304 stainless steel inflation valves, precision pressure gauges, and sealing gaskets. Large-tonnage products are equipped with special lifting ears, anti-collision panels, fixed chains / snap locks, and some can be paired with floaters and installation brackets to meet diverse installation requirements.

Manufacturing Process:

Precision Cutting: Utilizing CNC laser cutting technology, precise cutting of the material fabric is carried out to ensure a dimensional error of ≤ 1%, meeting the requirements for the formed shape after inflation.
Reinforced Double Stitching: At key seams, double-thread sewing combined with heat-pressed edge sealing technology is employed to enhance the sealing performance and tear resistance, preventing air leakage or thread breakage after inflation.
High-Pressure Heat Bonding: The fabric seams undergo high-temperature and high-pressure heat bonding treatment, achieving high fusion and enhancing the overall structural strength to withstand collisions and impacts in marine environments.
Multi-Layer Coating Treatment: The surface is sprayed with UV protection layer and wear-resistant coating for dual protection, isolating ultraviolet rays and seawater erosion, and prolonging the service life.
Strict Air-Tightness Testing: The finished product undergoes a 24-hour high-pressure inflation test, with a pressure retention rate of ≥ 98%, ensuring no hidden leaks and stable sealing.
Edge Reinforcement Molding: The edges are treated with thickened edge wrapping and reinforced fastening design to strengthen the stressed points and prevent wear and deformation over long-term use.

Features:

High energy absorption efficiency, gentle reaction force: The core relies on the elastic deformation of compressed air to absorb the kinetic energy of ships during berthing. The energy absorption efficiency is much higher than that of rigid anti-collision facilities, and the reaction force on the ship body and the dock is uniform and gentle, effectively protecting the steel plates of the ship body and the concrete structure of the dock from hard collision damage.
Comprehensive scene compatibility, full specification coverage: From the φ200mm small specification suitable for small fishing boats / yachts to the φ5000mm large tonnage suitable for large container ships / LNG vessels, the diameter, length, and working pressure can be customized as needed. It is suitable for all water areas including inland rivers, coastal areas, and oceanic areas, as well as all scenarios of docks, ships, and offshore platforms.
Excellent weather resistance, strong environmental adaptability: The rubber material can withstand extreme temperatures of **-40℃ to +60℃**, is resistant to seawater, acids, alkalis, salt fog, and ozone corrosion, and is resistant to aging and ultraviolet rays. It can be used stably in outdoor marine environments for a long time without special protection.
Flexible installation, convenient operation: Supports various installation methods such as fixed on the side wall of the dock, suspended on the side of the ship body, combined floating with buoys, and fixed with mobile supports. It can be put into use after reaching the inflation standard. Daily maintenance only requires regular inspection of the air pressure and a small amount of air replenishment. The operation is simple, and the labor cost is low.
Safe and reliable, long service life: Under normal conditions, there is no risk of explosion or sinking. The deformation recovery is fast, and it can continuously withstand repeated berthing impacts of ships. The regular use lasts for 7-10 years, and the large-tonnage thickened model can last for more than 10 years. The cost performance is high.
Strong customization, suitable for special needs: Special treatments such as flame retardancy, anti-static, and ultra-metallized coatings can be made according to the scene to meet the requirements of dangerous goods docks, high-friction operation areas, etc.
