Qingdao Manufacturer ISO17357 Authenticated Factory Price Offshore Platform Protection Yokohama Fender Rubber Boat Marine

Pneumatic rubber fenders, also known as Yokohama fenders, are manufactured from rubber and multiple layers of rubber-dipped tire fabric. They serve as leading anti-collision devices for marine applications worldwide.

These floating pneumatic rubber fenders are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables them to float on water and function as shock absorbers between ships (ship-to-ship) or between ships and berthing structures during docking operations.

• Lightweight design for easy handling and installation with guy-ropes or chains
• Resists shearing force and maintains energy absorption under inclined compression up to 15 degrees
• Available in diameters from 500 mm to 4,500 mm and lengths from 500 mm to 9,000 mm
• Available as sling-type or with heavy-duty chain & tire net configurations
• Vertical hydro pneumatic fenders available for submarines
• Compliant with ISO 17357:2014 standard

• Reinforced synthetic-tire-cord layers providing strong stability, heat resistance, and excellent fatigue resistance
• No mold vulcanization with advanced surrounding molding process
• Single-piece rubber capsule wall formation eliminating secondary joints and weak points
• Thin, soft walls with excellent contact deformation performance and high energy absorption
• Superior adaptability to inclined contact up to 15 degrees
• Floating design accommodating multi-directional ship docking
• Easy installation and maintenance

Ships typically make initial contact with docks or other vessels at oblique angles during STS operations. Unlike solid rubber or foam fenders, inflatable rubber fenders maintain rated reaction force and energy absorption even at inclined compression up to 15 degrees, providing consistent performance regardless of approach angle.

Zhonghaihang Pneumatic Rubber Fenders are constructed with three primary components:

• 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 fittings with internal and external flanges secured by bolts and nuts, with a central valve similar to automotive tire valves.

• Maintain fender pressure within standard air pressure ±5% range
• Check air pressure every three months and adjust as needed
• Avoid contact with sharp objects
• When not in use for extended periods: wash, dry, fill with appropriate 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

1) Strict detection during production. 2) Strict sampling inspection on products before shipment and intact product packaging ensured.

1) Keep the fender away from sharp objects to prevent damage
2) Fender cannot contact with acid, oil, or other organic solvents
3) When not in use for extended periods: wash, clean, dry, and inflate with proper compressed air. Store in dry, cool, ventilated areas
4) Storage areas should be away from heat sources
5) Do not place heavy objects on fenders when not in use
6) Check inner pressure every 3 months during normal use. Replace air valve core every 6 months
