Yokohama Type 4.5m X 12m Floating Pneumatic Rubber Fender
 

Product Description:

Material Advantages:
It adopts a three - layer composite structure to ensure durability and airtightness. The outer layer is made of high - density natural rubber, which has strong tensile, tear - resistant and wear - resistant properties, and can resist the erosion of harsh marine environments such as wind, sun and seawater. The middle layer is a reinforced synthetic tire cord layer, which can stably maintain the internal air pressure of the fender and avoid deformation during impact. The inner layer is a rubber sealing membrane, which has excellent airtightness to prevent air leakage. In addition, it is equipped with a tire chain net for external protection, and the metal parts at both ends include end flanges with inflation and safety valves to facilitate pressure regulation and safety protection.

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%.

Feature:

It strictly complies with the ISO 17357:2002 international quality standard, and has obtained multiple authoritative certifications including CCS, BV and LR. These certifications fully verify the product's quality and performance, and make it meet the access requirements of maritime markets in various countries and regions.

Application:

It is an ideal collision - avoidance equipment for large tankers, LPG ships, bulk carriers, offshore platforms, large docks and wharves. It is applicable to ship - to - ship and ship - to - dock berthing and transfer scenarios. It can adapt to different sea conditions such as large tide ranges and protect the hull and dock structure from collision damage. At present, it has been exported to many countries and regions such as Germany, the United States, Singapore and Vietnam.
