Where is the quality of rubber fenders?
- 2019-04-23-

With the opening of China's shipping industry, the need for docks and marine fenders is increasing, and the demand for fenders is increasing. In the meantime, rubber fenders are widely used for good patience and impact resistance. At present, there are many manufacturers of rubber fenders in China, and the products are incomplete. Some manufacturers are in the midst of a fierce competition. They are the first to focus on price comparisons, not strictly adhere to relevant standards and processes, and use low-quality raw materials or Excessive use of reclaimed rubber to reduce costs, which poses a great danger to the docks and ships berthing. Relevant experts have indicated that rubber fenders should implement relevant standards, cruel process, enhance self-reliance and innovation, continuously improve the quality of goods, and provide fixed and safe products for China's shipping industry and shipbuilding industry.


It is understood that there are various specifications for rubber fenders on the raft, and there are mainly buckling type, inflatable type, laterally loaded cylindrical type (drum type), butted V type (ie type X) and flexible pile type. In the attempt and the production of rubber fenders , the manufacturer should consider the reaction force of the hull and the docking ship components, the deformation of the fenders after the kinetic energy of the ship, the deformation of the fender deformation, the reaction force of the hull, and the relative of the fender. The effectiveness of the fender energy absorption during stiffness, non-positive thrust, the rate at which the fender slows down the ship's berthing rate, the friction coefficient between the fender and the hull, the fender and the structural investment of the support member and There are many factors such as the cherished use and the touch method of the hull. Users can choose different rubber fenders according to the actual conditions. In addition to tugboats and small vessels, large-tonnage vessels are usually not equipped with rubber fenders. When berthing, they mainly use inflatable rubber fenders to cherish the pier and hull.


The person concerned indicated that the quality of the goods is the first. If the new ship is hit by a new ship at the dock due to the quality of the rubber fender, and the hull is damaged, the new ship will not be reworked and even delayed. Although the rubber fenders are not attributed to the shipbuilding company's primary production equipment, the shipyards also pay attention to the price/performance ratio of the rubber fenders, but the quality of the goods cannot be ignored.
