As a professional supplier of Marine Inflatable Rubber Fenders, Aorunda's technical department insists on using high-strength hanging rubber curtain fabric as the skeleton material to create tightly structured rubber sealed containers.
This type of docking ball can float steadily on the water surface after being filled with compressed air, and is an indispensable physical buffering medium in the process of ship to ship berthing (STS) and ship to dock berthing (STD).
Its core advantage lies in its ability to deeply absorb the impact energy generated by the movement of ships, providing a hardcore guarantee for the safety of ship berthing by weakening the instantaneous recoil force.
Marine inflatable rubber fenders can absorb a large amount of impact energy, reducing the impact force on ships. Due to their elasticity, they are not easily deformed after compression.
In practical use, our products are lightweight, easy to install, and their oblique compression performance remains unaffected. They have a wide range of applications, and you can choose between chain suspension or tire net mounting according to your needs.
Their specifications and dimensions can be customized, making them suitable for oil tankers, container ships, yachts, offshore platforms, large shipyards, military ports, and large bridge piers.
1. Rubber Formulation: Marine Inflatable Rubber Fenders use high-quality natural rubber as the main raw material, along with various auxiliary materials such as styrene-butadiene rubber. The rubber content of the sphere can reach over 50%, and the tensile strength of the rubber exceeds 20 MPa.
2. Reinforcement Material: Single-strand and three-strand nylon impregnated cord fabric are used, with a breaking strength of 313.6 N per single cord.
3. Corrosion Resistance: Since the spheres operate in seawater for extended periods, they are more susceptible to seawater corrosion. Therefore, the flanges used for the inflatable rubber spheres require anti-corrosion treatment, and all fittings are made of stainless steel to ensure a longer service life and reduced maintenance frequency.
4. Structural Optimization: Using advanced 3D animation simulation technology, simulation experiments are conducted on the docking speed, buffering force, and collision direction during ship-to-dock berthing. This allows for the calculation of the maximum stress coefficient on the berthing sphere and the determination of the most reasonable structural layout.
The protective cover type inflatable rubber fender relies on a spherical body, which is covered with a protective cover on its surface. This cover consists of a chain, steel wire rope or nylon rope net, and old tires or rubber sleeves.
The longitudinal breakpoints of the chain, steel wire rope, or nylon rope net are connected to one or two adjacent meshes of the net cover by cables or ropes. Old tires or rubber sleeves are attached to the net cover to protect the spherical body.
Features of A1-Protective Cover Type Inflatable Rubber Fender:
(1) The chain surface is heat-treated, effectively enhancing its resistance to seawater corrosion.
(2) The use of nylon ropes makes fender installation simple and convenient, and easy to transport.
(3) The tires on the net cover provide sufficient space between the fender and the hull, thus protecting the fender from wear and extending its service life.
The suspended inflatable rubber ball is a spherical object without a mesh tire cover on its surface. It is equipped with lifting and rotating mechanisms on both sides, facilitating movement and allowing the ball to rotate more flexibly during operation to withstand impacts from various angles.
The ribbed inflatable fender, also known as the fishbone inflatable fender, can be customized with diameters ranging from 0.3 meters to 3.5 meters and lengths from 1 meter to 9 meters. It is one of the main product types of Aorunda Marine Inflatable Rubber Fenders.
Compared to traditional inflatable rubber fenders, this product has been upgraded. Currently, there are few manufacturers in China that can produce ribbed fenders, and Aorunda is one of them.
Compared with ordinary inflatable fenders, the ribbed inflatable fender requires a higher-quality formula and more precise structure and manufacturing process. It requires strong and extensive rubber formulation and process technology support to be successfully manufactured.
It is a highly recommended product; in addition to its more aesthetically pleasing and practical appearance, its compressive strength, durability, airtightness, and corrosion resistance are far superior to ordinary inflatable fenders.
The surface ribs can more effectively protect the fender body, increase friction, and act as a buffer against compressive forces during contact between ships or between ships and docks.
