Pneumatic Fender 2.5x5.5m High Energy ISO Certified Durable Yokohama Type Fender fully comply with all requirements of ISO17357

Product Description:

Material Advantages:

Utilizing high-strength synthetic rubber (such as a blend of natural rubber and styrene-butadiene rubber), with an elastic recovery rate exceeding 90%, it can quickly absorb the impact of ship berthing, reducing damage to the dock and the ship's hull.

The rubber material is highly dense, exhibiting excellent wear resistance, with a Shore hardness of 60-70A, allowing it to withstand long-term friction without easily cracking or chipping.

It possesses good weather resistance and corrosion resistance, able to withstand harsh environments such as seawater, ultraviolet radiation, and extreme temperatures (-40℃ to 60℃), extending its service life by more than 30%.

The material is non-toxic and environmentally friendly, containing no heavy metals or other harmful substances, and will not pollute the marine environment, meeting marine environmental protection standards.

Manufacturing Process:

Material Pretreatment: Synthetic rubber raw materials are mixed with reinforcing agents, antioxidants, and other additives in precise proportions, and then plasticized at 120-150℃ using an internal mixer to ensure uniform rubber texture and stable elasticity.

Skeleton and Airbag Molding: High-strength polyester cord fabric is used as the skeleton layer, wound into a 600*1000mm cylindrical structure, with an inner rubber airtight layer. Preliminary shaping is achieved using a vulcanizing machine to ensure airtightness.

Overall Vulcanization Process: The molded fender is placed in a large vulcanizing tank and vulcanized at 150-160℃ and 1.5-2.0MPa pressure for 4-6 hours to allow the rubber molecules to fully cross-link, improving material strength and anti-aging properties.

Accessory Assembly and Sealing: Inflation valves, flange joints, and other accessories are installed. Secondary vulcanization sealing is used at the interfaces to ensure no air leakage. A wear-resistant protective coating is applied to the outer layer to enhance surface abrasion resistance.

Finished product inspection: Products pass airtightness tests (pressurized to 0.3-0.5MPa and held for 24 hours without leakage), impact resistance tests, and dimensional accuracy tests. Unqualified products are reworked directly, and the factory pass rate is over 99%.

Features:

Long-lasting and durable: Utilizing patented air-retaining technology, the annual air pressure decay rate is ≤5%. It maintains stable performance even after 3000 dynamic compression tests, and its service life far exceeds that of traditional anti-collision devices.

Easy installation: Equipped with end flanges, inflation valves, and safety venting devices, it can be quickly hoisted and secured without complex auxiliary equipment.

Precise specifications: Measuring 2.5m in diameter × 5.5m in length, it balances buffer capacity with installation space, suitable for the protection needs of medium to large-sized ships.

Technical Parameters:

Applications:

Commercial Ports: Suitable for berthing of various vessels such as container ships and tankers, protecting the quay walls and ship sides from impacts.

Ship-to-Ship (STS): Provides stable buffering for two vessels in scenarios such as offshore refueling and cargo transfer, reducing the risk of collision in rough seas.

Energy Terminals and Offshore Facilities: Suitable for personnel/material transfer protection at oil and gas terminals, LNG carrier berthing, and offshore drilling platforms.

Specialty Terminal Projects: Can serve as a core component of collision avoidance systems for naval ports, floating docks, and bridges, adaptable to high-load operation requirements.
