Ship fuel hoses are an indispensable part of the ship's fuel system, and their main function is to transport and distribute fuel. Due to the frequent influence of various factors such as waves, wind, temperature, etc. on ships during navigation, the fuel hoses of ships need to have specific performance characteristics to ensure the safety and reliability of navigation. Firstly, ship fuel hoses need to have performance characteristics of high pressure resistance, high temperature resistance, and corrosion resistance. During navigation, the ship's fuel hoses need to withstand various pressure and temperature changes, as well as face corrosion from seawater, oil stains, and chemicals. Therefore, ship fuel hoses need to have excellent resistance to high pressure, high temperature, and corrosion to ensure normal operation in various environments. Secondly, ship fuel hoses need to have excellent sealing performance. Fuel is prone to leakage during transportation, which not only affects the economy of navigation but also causes pollution to the marine environment. Therefore, ship fuel hoses need to use high-quality sealing materials and advanced sealing structure design to ensure reliable sealing under various pressure and temperature changes. In addition, marine fuel hoses also need to have excellent anti-aging performance and anti fatigue performance. Ships will encounter various complex environmental factors during navigation, such as temperature changes, mechanical vibrations, etc., which can have a certain impact on the ship's fuel hoses. Therefore, marine fuel hoses need to be made of materials with high strength and elasticity, and adopt special anti-aging and anti fatigue design to ensure that aging, fatigue and other problems will not occur during long-term use. In addition, ship fuel hoses also need to have the characteristics of simple structure, easy installation and maintenance. Due to the need to ensure the normal operation of the fuel system during navigation, the installation and maintenance of fuel hoses on ships also need to be more convenient and efficient. Therefore, the design of ship fuel hoses needs to consider the characteristics of simple structure, easy installation and maintenance, in order to quickly repair and replace them in case of faults. In a word, the marine fuel hose is a very important part of the marine fuel system. It needs to have the advantages of high pressure resistance, high temperature resistance, corrosion resistance, good sealing performance, strong aging resistance, good fatigue resistance, simple structure, easy installation and maintenance, etc. Only in this way can the safety and reliability of the ship during navigation be ensured, while also improving the economy and environmental protection of navigation.
