Inflatable Marine fender

The ship's fender consists of synthetic rubber ropes and compressed air. The fender works by compressing the air and floating it on the surface of the water, so that the working boat plays a role of shock absorption or collision avoidance when it is moored.

The inflatable rubber fender is called the inflatable rubber fender (against the ball), and the fender is divided into an inner rubber layer, a strengthened layer, an outer rubber layer and a three-layer component. It is characterized by good weather resistance, long service life, puncture resistance, impact resistance, oil erosion resistance, sea water erosion, environmental protection and no pollution to the environment and many other advantages depend on customers.

Rubber fenders can be used to protect the side of a ship when it comes to landing, or when it encounters some emergency impact. Marine fender is a very important protection tool.

All ships going to sea are usually equipped with such inflatable balls, but the quality of the product directly affects the performance of the product, and working at sea is a challenging and dangerous job, so it is necessary to be prepared. Then, in order to ensure our personal safety, and will fully achieve the purpose of our sea travel, so we must look for brands and quality when buying rubber fenders.

How to replace and install rubber fender

Rubber fender is a kind of widely used anti-collision equipment in wharf. Since the 1970s, it has been widely used in wharves and ports in China. Due to frequent collisions and the natural aging of rubber, the service life of rubber fenders is generally only 10 years. However, the service life of docks and ports is much more than 10 years, so docks and ports must be replaced with rubber fenders during use. At present, the more common method of replacing rubber fender is to replace it with D-type foam fender. At the same time, many small and medium-sized terminals, such as Haikou port, have been replaced by the used tire chain type suspension cable fender.

Project introduction

A gravity pier 120 meters long and 20 meters wide was built in the 1980s. As the original fender was worn out and the shape of the dock changed, it was necessary to replace and install a new rubber fender. Rubber fender used in this project Each rubber fender has 8 M24 bolts. When the compression deformation of the rubber fender reaches 50%, the maximum reaction force of the rubber fender is 686.7kN, and the tensile strength of each bolt after anchoring is greater than 86kN, which meets the requirements of engineering use. A total of 120 rubber fenders and 960 bolts were required for the project.

The port is a haven with a design high water level of 3.80 meters, a design low water level of 0.40 meters, an average high water level of 2.3 meters, and an average low water level of 1.20 meters. Rubber fender bolt minimum level -1.60 meters, rubber fender underside -1.80 meters, rubber fender bolt minimum level -2.50 meters, rubber fender underside height -2.65 meters

Inner rubber and reinforcing layer

The inner rubber of the fender is closely combined with the reinforcing layer, and the inner rubber increases the tightness of the fender.

Coating rubber

Protective cord layer and interior rubber. It has the advantages of wear-resisting, anti-piercing, anti-ultraviolet, anti-aging, anti-seawater erosion, anti-static, flame retardant and so on.

Reinforced nylon curtain

It is composed of hanging rubber curtain cloth, and the internal air of the fender is subjected to external extrusion pressure to generate external tension, ensuring that the explosion-proof type is not subjected to external extrusion and explosion. The reinforced layer increases the tensile strength of the fender and withstands the extrusion pressure.
