Henger Pneumatic Rubber Fenders: Safe, Durable & Efficient in All Scenarios

1.Introduction to Pneumatic Rubber Fenders

1.Outer Rubber

The outer rubber layer, which covers the fender's exterior, protects the cord layers and inner rubber from abrasion and other external forces. This rubber compound boasts sufficient tensile and tear strength to withstand various weather conditions and heavy-duty use. The standard color is black, with other colors available upon request.

2.Inner Rubber

The inner rubber, a rubber membrane liner, ensures the pressurized air inside the fenders is properly sealed.

3.Synthetic Tire Cord Layers for Reinforcement

The reinforcement layers, crafted from synthetic tire cords commonly used in tires, are arranged at optimal angles. They effectively withstand internal pressure, distribute stress evenly, and provide strong, efficient reinforcement.

4.Beading Ring

A steel ring is positioned at one or both ends of the fender to secure the ends of the cord layers firmly.

5.Flange

A steel flange is installed on the fender, capable of being fitted with an air valve or a safety valve.

6.Safety Valve

Fenders with a diameter of 2500mm or larger must be equipped with a safety valve, which functions to release excess internal pressure when the fenders are accidentally over-compressed. For fenders with a diameter smaller than 2500mm, a safety valve can be installed as required.

7.Metal Accessories

All relevant metal accessories of pneumatic fenders, including shackles, towing rings, swivels, and chain nets, are made of stainless steel, offering excellent resistance to seawater corrosion.

Unique Design of Henger Pneumatic Rubber Fenders

1.Active - Protecting Safety Valve: All fenders are equipped with a safety valve to release internal air in case of accidental overpressure. This patented design can prevent the fenders from exploding due to collision and inflation.

2.Henger Flange: It is cast from corrosion - resistant cast iron with a galvanized anti - corrosion coating. This can significantly extend the quality and service life of the fenders. The strength of Henger cast flanges is 40% higher than that of traditional types.

4.Our advantages

1.Safety and Reliability​

Henger pneumatic rubber fenders are crafted from premium natural rubber and reinforced with multiple layers of high-strength tire cords, delivering exceptional resistance to pressure and cuts. Their design incorporates a safety factor grounded in well-recognized engineering principles, validated through rigorous experimental testing to ensure consistent, optimal performance in real-world operational environments.​

2.Patented Active-Protecting Safety Valve Design​

Each Henger pneumatic rubber fender is equipped with a patented safety valve, engineered to automatically release internal air in cases of accidental overpressure. This proactive protective mechanism effectively prevents potential damage, enhancing overall operational safety.​

3.Consistent Performance with No Deterioration​

By utilizing the compressive elasticity of air, Henger pneumatic rubber fenders maintain unwavering performance integrity over extended periods. They eliminate the risk of degradation caused by material fatigue, even under prolonged and frequent use.​

4.Superior Performance in Inclined Berthing Scenarios​

A standout advantage of Henger pneumatic rubber fenders is their stable energy absorption capability: even when subjected to inclined compression angles of up to 15 degrees, their energy absorption efficiency remains entirely uncompromised.

5. Pneumatic Rubber Fender Application

There are two typical installation types: ship - to - ship operation and ship - to - dock operation.

a. Ship - to - ship operation
Generally, two contact points are sufficient for light - duty ship - to - ship operations. However, for heavy - duty ship - to - ship operations, 1 or 2 additional pneumatic rubber fenders should be used as the primary fenders. They can absorb the berthing energy and maintain a proper stand - off distance between the two ships. At the same time, two or more small - size fenders can be hung on the ship hull as secondary fenders.

b. Ship - to - dock operation
Pneumatic fenders are often used in ship - to - quay operations due to their excellent performance. The pneumatic fenders are anchored to the quay with guy chains and shackles. Meanwhile, the pneumatic fenders can float on the water surface according to the change of tides.

6. Pneumatic Rubber Fender Transportation

In terms of transportation, we can adopt deflated pallet transportation or full fender transportation without deflation according to customer requirements. We always put customer needs first.

7. Pneumatic Rubber Fender storage

1.When pneumatic rubber fenders are not used for a long time, they should be cleaned and dried, filled with appropriate compressed air, and stored in a dry, cool, and ventilated place. The storage temperature should be maintained at - 15℃ - 40℃.

2.The storage place of the fenders should be far away from heat sources.

3.The fenders must not come into contact with acids, alkalis, greases, and organic solvents.

4.When not in use, the fenders must not be stacked, and should not be placed on the ba. To better extend the service life of pneumatic rubber fenders, it is recommended to store them in strict accordance with the above recommendations.

8. After-sale service

1.The product warranty period of Henger is 24 months, which is longer than that of the average supplier. This also reflects the trust between us and our customers in the products of our factory.

2.Our after - sales service is available 24 hours a day. As long as you have any questions, we will always be here. Professional staff will answer your questions and provide you with technical support.

3.Transportation: We can adopt deflated pallet transportation or full fender transportation without deflation according to customer requirements. We always put customer needs first.
