Inflatable Cylindrical Marine Ship Fender Pneumatic Natural Rubber Fender ISO

Pneumatic rubber fenders, also known as Yokohama fenders, are manufactured using rubber and multiple layers of rubber-dipped tire fabric. These represent the leading anti-collision devices for marine applications worldwide. Floating pneumatic rubber fenders are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside, enabling them to float on water and serve as shock absorbers between ships (ship-to-ship) or between ships and berthing structures.

• Reinforced synthetic-tire-cord layers providing strong stability, heat resistance, fatigue resistance, and impact load resistance
• No mold vulcanization with advanced surrounding molding process
• Single-formed rubber capsule wall eliminating secondary joints and improving overall strength
• Thin, soft walls with excellent contact deformation performance and large energy absorption
• Superior adaptability to inclined contact up to 15 degrees
• Floating capability allowing application during ship swaying and accommodating docking from all directions
• Easy installation and handling

Ships typically make initial contact with docks or other vessels at oblique angles during STS operations. Unlike solid rubber or foam fenders that experience reduced performance at inclined compression, inflatable rubber fenders maintain their rated energy absorption even at compression angles up to 15 degrees.

Our pneumatic fenders are available in sizes compatible with various ship tonnages, ensuring optimal protection for vessels of all sizes.

Pneumatic rubber fenders are essential for marine safety in various scenarios including ship-to-ship transfers, berthing operations, and port facilities.

Zhonghaihang pneumatic rubber fenders consist of three primary components vulcanized into a single, durable unit:

• Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with superior tensile and tear resistance
• Reinforcement Synthetic-Tyre-Cord Layer: Maintains internal air pressure with exceptional strength and stability
• Inner Rubber Layer: Seals pressurized air inside the fender

Fenders with diameters of 2500mm and larger include safety valves to release excess internal pressure during accidental over-compression. The assembly features metal end components with dual flanges and bolt/nut clamping, with a center valve similar to automotive tire valves.

• Maintain fender pressure within ±5% of standard air pressure
• Check air pressure every three months and adjust as needed
• Avoid contact with sharp objects
• When not in use for extended periods: clean, dry, inflate with proper compressed air, and store in cool, dry, ventilated areas
• Storage areas should be away from heat sources, acids, alkalis, oils, and greases
• Do not fold or stack fenders during storage

Our pneumatic fenders can be easily installed using guy-ropes or guy-chains due to their lightweight construction, providing flexible installation options for various marine applications.
