Rubber fender is a kind of anti-collision equipment made of rubber material. It is widely used in docks. It has been widely used in our terminals and ports since the 1970s. Rubber fenders typically have a service life of only 10 years due to frequent collisions and natural ageing of the rubber. However, the port and port have a service life of more than 10 years, so the port and port must be replaced with rubber fenders during use. At present, the most common way to replace rubber fenders is to replace them with D-type rubber fenders . At the same time, there are many small and medium-sized terminals below 3000t, such as Haikou Port, which are replaced with waste tire anchor chain suspension fenders.

How is the rubber fender replaced? Let's talk about the following small series:

The material of the steel rubber fender should be the same as the raw material of the corresponding hull plate. It is constructed in two types: tubular and tubular.

The two ends of the rubber fender shall have a sealing plate and shall be chamfered, and gradually transition to a gradual disappearance. The height to width ratio of the beveled end shall be greater than 3:1, and the length shall be determined. If there is a composite plate, the composite plate shall be at the end dimension. Partial relaxation is strengthened.

The end of the rubber fender should fall on the constructed ribs inside the hull, such as ribs and ribs. If the rubber fender is provided with a composite plate, such as two 50~75mm narrow-side flat steel or a wide-side flat steel with a plug welding hole, when the composite plate and the double-plate are welded, the composite plate is used with 1.0-1.5mm copper plate and The outer plates of the hull are separated, and with the active development of the pre-installation project, the rubber fenders are often pre-installed on the sections. Therefore, the fender should be left in the section of the large seam at 1.0 to 1.2 m in bulk. Once the segment has been tested for large seam tightness, the device for the fender is available. The transverse and longitudinal ribs in the rubber fender are usually not welded to the hull plate, leaving a gap of 8 to 10 mm.
