As a professional manufacturer with its own advanced factory in China, SunKai has long been committed to providing high-quality marine anti-collision solutions. The SunKai Low Pressure Pneumatic Rubber Fender is a professional anti-collision equipment specially designed for ship berthing and mooring scenarios, integrating reliability, safety and cost-efficiency to provide all-round anti-collision protection for port, wharf and ship operations.
This Rubber Fender adopts a low-pressure inflatable structure, which can effectively absorb and disperse the impact force between ships and docks or between ships, avoiding damage to the hull and port facilities. As a commonly used anti-collision protection equipment in port, wharf and ship operations, its core structure uses high-strength synthetic fiber fabrics (such as nylon and polyester) as the inner tube skeleton, and the outer layer is covered with wear-resistant and anti-aging rubber materials, forming a flexible buffer by filling low-pressure air (usually working pressure 0.02-0.08MPa). With strict quality control and advanced manufacturing technology, it has become the preferred choice for customers in marine anti-collision fields.
- High Impact Capability: Equipped with excellent impact resistance, it can effectively absorb and disperse impact force during ship berthing and collision, reducing damage to hulls and port facilities.
- High Anti-Collision Shrinkage and Twisting Capacity: It has strong shrinkage and twisting resistance, and can maintain stable performance even when subjected to irregular collision forces, ensuring comprehensive anti-collision protection.
- Explosion-Proof Structure Design: Adopts a new type of explosion-proof structure design, which avoids safety hazards such as explosion caused by excessive pressure, and improves the safety of use in harsh working environments.
- Optimized Structural Layout: The structural layout is scientifically optimized, which enhances the overall stability and impact resistance of the fender, and extends the service life of the product.
- Durable, Aging-Resistant and Wear-Resistant: The outer layer is made of high-quality rubber material, which has excellent durability, aging resistance and wear resistance, and can adapt to long-term harsh working conditions.
- Higher Curvature and Damping Capacity: It has higher curvature and damping performance, which can better fit the hull surface, improve the buffer effect, and further reduce the impact damage.
- Seawater Corrosion Resistance: The material has strong seawater corrosion resistance, and long-term immersion in seawater will not cause damage such as cracking and corrosion, ensuring stable performance in marine environments.
For maritime operations demanding superior protection and operational flexibility, advanced fendering solutions are essential. Our Marine Low Pressure Pneumatic Fender is engineered to meet these critical needs. Designed as a versatile barrier between vessels and docks or between two vessels, this fender system excels in challenging offshore and harbor conditions. The Ship Low Pressure Pneumatic Fender is particularly valued for its high energy absorption and low reaction force, which safeguards both the ship's hull and the berthing structure from impact damage. When you require a reliable, durable solution, our Pneumatic Fender Low Pressure Type offers unparalleled performance. Its inherent buoyancy and robust construction make it an ideal choice as a Floating Low Pressure Pneumatic Fender for temporary mooring, ship-to-ship transfer operations, and as a permanent fixture on jetties.
The core advantage of the Low Pressure Pneumatic Rubber Fender lies in its sophisticated design and material science. Constructed from multiple layers of high-tensile strength synthetic tire cord, embedded within specially compounded rubber, the fender body is built for extreme resilience. An internal air chamber, maintained at a low operational pressure, allows for significant deflection upon impact, absorbing kinetic energy smoothly and efficiently. This design principle ensures a consistent, low reaction force is transmitted, minimizing stress concentrations. The outer rubber layer is resistant to abrasion, weathering, ozone, and oil, ensuring a long service life even in harsh marine environments. Standard accessories, such as wear panels, chains, and valves, are designed for easy installation and maintenance, making the Pneumatic Rubber Fender a practical and cost-effective long-term asset for any maritime facility.
- Reliable Buffer Protection Performance: Relying on the compressibility of low-pressure air, it can gradually absorb impact force through its own flexible deformation during collision, avoiding scratches or dents on the ship's shell and dock structure due to hard contact, and is especially suitable for berthing of large-tonnage ships. Compared with rigid fenders, the protective effect is softer and less likely to damage the protected object.
- Stable Working Pressure: The working pressure is stably controlled at 0.02-0.08MPa, and the built-in pressure gauge can monitor the air pressure in real time, ensuring that the fender maintains optimal buffer performance during use.
- Excellent Energy Absorption Capacity: It has excellent guaranteed energy absorption (GEA) performance, which can effectively absorb collision energy according to different specifications, and the energy absorption value can reach 6-9037 KJ (depending on the product specification).
- Controllable Reaction Force: The reaction force at GEA deflection is controllable, with a tolerance of ±10%, which can avoid excessive reaction force causing damage to ships and docks, and adapt to the anti-collision needs of different tonnage ships.
- Stable Hull Pressure: The hull pressure at GEA deflection is maintained at a reasonable reference value (122-208 kpa), which ensures effective buffer protection while avoiding damage to the hull surface.
- Strong Environmental Adaptability: It can maintain stable performance in various harsh environments, including long-term seawater immersion, outdoor sunlight exposure, and waters with alternating high and low temperatures, without frequent replacement.
- Lightweight and Easy to Operate: The overall weight of this Low Pressure Pneumatic Rubber Fender is light, installation does not rely on large lifting equipment, and can be completed manually with simple tools, improving the efficiency of installation and use.
