W-type rubber fender quality and safety are mainly reflected in several important aspects

Following the development of China's shipping industry, the demand for wharfs and W -shaped rubber fenders has been continuously added, and the demand for fender functions has also increased. In the meantime, W -type rubber fenders are the most widely used for good resistance and impact resistance. At present, there are many W -type rubber fenders in China, and the products are mixed. Some manufacturers make livelihoods in the fierce shopping mall competition. One-sided low-price competition is the primary method. It does not strictly follow the relevant norms and techniques, select low-quality raw materials or too much. Recycled rubber is used to reduce costs, which poses a significant risk to the safety of docks and ships. Relevant experts indicated that W -type rubber fender producers should strictly implement relevant national regulations, strict technical procedures, enhance their ability to stand on their own feet, continuously improve product quality, and provide reliable and safe products for China's shipping industry and shipbuilding industry.



It is understood that there are many types of rubber fenders on the market, mainly W -type rubber fenders , inflatable type, laterally loaded cylindrical type (drum type), butt-type V type (ie X type) and flexible pile type. When planning and producing rubber fenders, manufacturers should consider the reaction forces acting on the hull and dock ship components, the deformation of the fender after absorbing the kinetic energy of the ship, the reaction force of the fender deformation acting on the hull, the relative stiffness of the fender, The effectiveness of the fender energy absorption during non-positive thrust, the rate at which the fender decelerates the ship's berthing speed, the coefficient of friction between the fender system and the hull, the infrastructure investment of the fender system and support members and their protection costs, hull Many factors such as contact with the fender. Users can choose different types of rubber fenders according to their practice. In addition to tugs and small vessels, large-tonnage ships are generally not equipped with W -type rubber fenders . When berthing, they mainly use inflatable rubber fenders to protect the wharf and hull.

Relevant persons indicate that the quality of the products is the first. Assume that the new ship is bumping with the W -type rubber fender quality problem when it is being installed at the dock, and the hull is damaged. The new ship will have to rework and even form a delay. Although the rubber fenders are not attributed to the shipbuilding company's primary production equipment relative to the port, the shipyard also pays attention to the price/performance ratio of the W -type rubber fender , but the quality of the product must not be neglected.
