What is the maximum working pressure and temperature that a ship's hose can reach?

 

The maximum working pressure of a ship's hose depends on the material and structure of the hose, as well as the conditions of the operating environment. Generally speaking, the maximum working pressure of ship hoses can reach 200 bar or higher. For example, some high-strength polyester fibers or steel wire reinforced hoses can withstand higher pressures. However, when using hoses, it is necessary to select appropriate joints and valves based on the maximum working pressure of the hoses to ensure the safe and reliable operation of the system.

 

II Maximum operating temperature of ship hoses

 

The maximum working temperature of ship hoses also depends on the material and structure of the hoses, as well as the conditions of the usage environment. Generally speaking, the maximum operating temperature of ship hoses can reach 120 ° C or higher. For example, some hoses made of high-temperature resistant rubber materials can withstand higher temperatures. However, when using hoses, it is necessary to select appropriate materials and structures based on the maximum operating temperature of the hose to ensure its durability and reliability. In addition, when using in high-temperature environments, it is also necessary to pay attention to the heat dissipation of the hose to avoid performance degradation or damage caused by overheating of the hose.

 

III. Pressure and temperature testing methods for ship hoses

 

To ensure that the maximum working pressure and maximum working temperature of the ship's hoses meet the requirements, pressure and temperature tests are required. Generally speaking, pressure testing can be carried out using a hydraulic test bench or a gas pressure testing device. When conducting a hydraulic test, it is necessary to immerse the hose in water and gradually increase the water pressure until the hose leaks. When conducting a gas pressure test, it is necessary to connect the hose to the gas source and gradually increase the gas pressure until the hose leaks. When conducting temperature testing, equipment such as a hot box or hot water tank can be used. When conducting temperature testing, it is necessary to place the hose into the equipment and gradually increase the temperature until the hose undergoes deformation or damage. Through these testing methods, it can be ensured that the maximum working pressure and maximum working temperature of the hose meet the requirements, thereby improving the safety and reliability of the system.
