SunKai's high-quality Ship Low Pressure Pneumatic Fender is a professional anti-collision equipment specifically designed for ship berthing and mooring scenarios, serving as a core protective tool in port, wharf and ship operations. As a professional manufacturer with its own advanced factory in China, SunKai is committed to providing reliable, durable and cost-effective marine anti-collision solutions, focusing on safeguarding ship hulls, port facilities and ensuring safe berthing operations for global customers.
The fender adopts a low-pressure inflatable structure, with a core structure consisting of high-strength synthetic fiber fabrics (such as nylon and polyester) as the inner tube skeleton, and the outer layer covered with wear-resistant and anti-aging rubber or PVC materials. By filling low-pressure air (usually working pressure 0.02-0.08MPa), it forms a flexible buffer that can effectively absorb and disperse the impact force between ships and docks or between ships, avoiding damage to the hull and port facilities.
Using a low-pressure inflatable structure to effectively absorb and disperse the impact force between ships and docks or between ships, avoiding damage to the hull and port facilities, and providing reliable anti-collision protection for ship berthing and mooring operations.
Through a strict four-step manufacturing process—material pretreatment, inner tube forming, outer wrapping, and detection and repair—each fender is ensured to have excellent airtightness, impact resistance and durability. It is widely applicable to various scenarios, from small yacht berths to large container ship terminals, and is especially suitable for small and medium-sized ports or scenarios that require frequent adjustment of protective positions, providing reliable anti-collision protection for all types of ship berthing and mooring operations.
In the demanding world of maritime operations, protecting vessels and berthing structures from impact damage is paramount. This is where our advanced Low Pressure Pneumatic Rubber Fender excels. Engineered for superior energy absorption and resilience, these fenders are the ideal solution for a wide range of docking and mooring scenarios. Whether you are securing large commercial ships, offshore service vessels, or specialized barges, our Marine Low Pressure Pneumatic Fender provides exceptional performance and durability. The unique design of the Pneumatic Fender Low Pressure Type ensures a larger contact area and lower surface pressure compared to traditional high-pressure fenders, significantly reducing the risk of hull damage and structural wear. Its inherent buoyancy and flexibility make it particularly effective in challenging sea conditions. For applications requiring additional flotation and visibility, our Floating Low Pressure Pneumatic Fender offers enhanced stability and is easily deployed in ports, harbors, and alongside quay walls.
The Ship Low Pressure Pneumatic Fender is meticulously constructed from high-grade, weather-resistant synthetic rubber, ensuring long-term performance even under constant exposure to sunlight, saltwater, and extreme temperatures. Its internal structure is reinforced with robust tire cords, providing exceptional tensile strength and tear resistance. The operational pressure is carefully calibrated to be lower than standard pneumatic fenders, which translates to a softer initial touch and a more gradual, controlled absorption of kinetic energy during berthing. This characteristic is crucial for safeguarding both the vessel's paintwork and the integrity of the fender itself. Key operational advantages include excellent resistance to compression set, meaning the fender returns to its original shape quickly after deflection, and low maintenance requirements due to its simple yet robust design. Installation is straightforward, typically involving standard mooring hardware, and its lightweight nature compared to solid rubber fenders allows for easier handling and logistics.
