Inflatable rubber fender introduction
Inflatable fenders are widely used in large ships, yachts, ocean platforms, and harbor terminals. It uses compressed air as a buffer medium to absorb the impact energy of the ship. Therefore, compared with the general compressed rubber fender, it has large energy absorption, small reaction force, large contact area with the ship, and small unit surface pressure acting on the ship. , The performance is not reduced when tilted and compressed, and the installation is simple and convenient. It can be adapted to the docking of ships in all directions.
This type of inflatable ball is equipped with a sheath outside, which is composed of galvanized chains and tires crossing each other, which can effectively protect the ball. The chain is made of anti-corrosion hot-dip galvanized material, and is covered with a rubber tube to prevent the chain from wearing the surface of the ball.
The fender is mainly to withstand the impact force of the ship when the ship is docking, leaving the dock and other forms (such as when the ship is tied to tow), and transmits it to the hull structure of a larger area. Wooden fenders have buffering effect. Although steel fenders have poor buffering effect, they have better strength and can be included in the section of the hull girder (the welding strength must be guaranteed). Especially for large-open deck barges, they can make up for the deck The lack of effective cross-sectional area is conducive to longitudinal strength. Steel materials cannot be used for the fenders of oil barges and small oil tankers.
The inflatable ball bearing of Qingdao Henger Ship Supplies Co., Ltd. is a new type of product that is used to install on the dock or ship to play a role in collision avoidance and buffering. According to the appearance, it is divided into three types: suspension type, sheath type, and thread type. After being filled with compressed air, it can float on the water (so it is also called floating fender or floating ball), which can be used as ship-to-ship berthing STS (ship to ship) and ship-to-ship berthing STD (ship to dock). To dock) is an important buffer medium that absorbs the impact energy of ship motion and has a small recoil force on the ship. Compared with general rubber fenders, it is more practical and economical.
Compared with general elastic rubber fenders (such as waste tires, solid rubber fenders, etc.), it has the advantages of large impact energy absorption, low pressure per unit area acting on ships, excellent impact fatigue resistance, and easy installation.
Since it was put into use in the market, with its excellent elasticity and wear resistance, the inflatable rubber fender has been used as a buffer medium for ship berthing and ship berthing, and is widely used in ship-to-ship operations and ship mooring operations.
Large seagoing vessels usually do not have fenders. River boats, work boats, permanent double-track fenders, one of which is located on the upper deck, and the other is located slightly higher than the designed waterline.
Floating Inflatable Fenders are used world wide for ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships. Since its creation until today,
more than millions of fenders have been supplied worldwide both for ship-to-ship and ship-to-dock (STD) operations serving our valuable customers.
These fenders play a critical role in the safe operation of ship berthing and mooring.
