ISO 17357 Compliant High Elasticity Natural Rubber Pneumatic Rubber Fender for

Product Description – Pneumatic Rubber Fender

Our Pneumatic Rubber Fenders are expertly crafted to deliver superior anti‑collision performance for vessels, terminals, and offshore facilities. Constructed from premium natural rubber and reinforced with high‑strength synthetic cord layers, these fenders are designed to absorb and dissipate berthing impact energy efficiently, protecting both ship hulls and port structures. Fully compliant with ISO 17357, they represent a benchmark of quality and reliability in the marine fendering industry.

Superior Material and Structural Design

The fenders are fabricated from carefully selected natural rubber compounds known for their exceptional elasticity, resistance to abrasion, and durability in aggressive marine conditions. Multiple layers of nylon or polyester reinforcement are embedded within the rubber matrix, providing outstanding burst resistance and structural integrity. Advanced manufacturing processes, including precision vulcanisation and airtight sealing, ensure consistent performance under fluctuating pressures and challenging environmental conditions. The smooth external surface minimises wear during contact, contributing to a longer operational life for both the fender and the vessel.

Certification and Quality Assurance

All our pneumatic rubber fenders are manufactured in full compliance with ISO 17357, the internationally recognised standard for marine fendering. They are available with a working pressure of 50 kPa or 80 kPa, allowing you to select the most suitable pressure level for your specific berthing requirements. To guarantee product integrity, each fender undergoes a mandatory air tightness test prior to deflation and packing. This test confirms that the fender maintains stable internal pressure without leakage, ensuring dependable performance in service. Additionally, we can arrange inspections by leading classification societies, including BV, DNV, LR, ABS, and CCS, to meet your project specifications.

Three Available Types

To accommodate diverse operational needs, we offer three standard versions:

• Sling Type – equipped with integrated lifting slings for straightforward handling and positioning.

• With Chain & Tire Net – features a protective chain and tire net covering, offering excellent resistance to cutting and abrasion in busy port environments.

• Submarine Type – specially designed for submerged installation, suitable for floating docks, tidal berths, and offshore platforms.

Customisation Flexibility

We recognise that each application has distinct requirements, and we provide extensive customisation to achieve the perfect fit. The fender’s diameter can be manufactured from 0.5 m to 4.8 m, and the length from 1 m to 12 m, covering a broad spectrum of vessel sizes from small tugs to very large crude carriers. The standard flanges are made of Q235 hot‑dip galvanised steel, offering robust corrosion resistance. For environments requiring enhanced anti‑corrosion properties, we offer flanges in 304 or 316 stainless steel. Other customisable features include working pressure adjustments, surface colour, and specialised fittings.

Safety Features

Each fender is equipped with safety valves at both ends, which automatically release internal pressure if it exceeds the safe threshold, preventing over‑inflation and potential failure. This design feature enhances operational safety and extends the service life of the fender. The fender's construction ensures high energy absorption with low reaction force, reducing peak impact loads on both the vessel and dock infrastructure. Its rapid response and recovery characteristics allow it to accommodate changing tidal levels and vessel approach angles effectively.

Stringent Testing Protocol

Before dispatch, every unit is subjected to a comprehensive quality control process. The air tightness test is conducted to verify that the fender maintains pressure integrity without any leakage over a specified period. Only after passing this test is the fender deflated, carefully folded, and securely packaged for shipment. For class‑approved projects, we coordinate with recognised classification societies to conduct witnessed tests and provide full documentation, including material certificates, inspection reports, and compliance records.

Warranty and After‑Sales Support

We are committed to the long‑term performance of our pneumatic rubber fenders, which is why we provide a 2‑year warranty covering manufacturing defects. Our after‑sales team offers installation guidance, maintenance recommendations, and responsive technical support. Routine maintenance is simple and cost‑effective, requiring only periodic pressure checks and surface cleaning.

Applications

These fenders are widely utilised in commercial ports, container terminals, ship‑to‑ship transfers, offshore platforms, ferry terminals, and mooring operations, providing reliable protection across a diverse range of marine sectors.
