2024-04-04

Alloy tubes are widely used in the aerospace industry, and their unique material properties make them the material of choice for many critical components.

Engine components: Alloy pipes are used to connect the oil pipeline between the fuel tank and the engine combustion chamber. These pipelines need to withstand high pressure and temperature, while also requiring good corrosion resistance and sealing to ensure the safe transportation and supply of fuel. The engine's lubrication system needs to deliver lubricating oil to various lubrication points to reduce friction and wear and protect engine components. Alloy pipes are used to construct lubricating oil pipelines. Their high temperature, high pressure and corrosion resistance properties enable them to maintain stability and reliability in harsh working environments. The engine's hot parts need to be cooled to prevent overheating damage. Alloy tubes are used to construct delivery pipes for cooling water or cooling gas in cooling systems to transfer heat away from critical components and dissipate heat. The exhaust pipes in the engine exhaust system also require the use of alloy pipes. These pipes need to have high-temperature, high-pressure and corrosion-resistant properties to withstand the impact of high-temperature gases and exhaust gases from the combustion process and effectively discharge them outside the aircraft.

Hydraulic system: The pipes in the hydraulic system are used to transport hydraulic oil or hydraulic fluid and transmit power and control signals. Alloy pipes are widely used in hydraulic transmission pipelines due to their high strength and corrosion resistance. These pipes need to withstand high pressure and impact forces, and also require good sealing to ensure stable operation of the system. The valve body and connecting parts in the hydraulic system also need to use alloy materials to ensure they have sufficient strength and corrosion resistance. These components need to withstand frequent stress and movement, so the high strength and durability of alloy pipes make them an ideal choice. The oil tank and oil pipes of the hydraulic system also need to use alloy materials to ensure their corrosion resistance and stability in harsh environments. These components need to withstand long-term immersion in hydraulic oil and high pressure, so the corrosion resistance and mechanical properties of alloy tubes are crucial to the reliability of the system.

Fuel system: Alloy pipes are widely used to connect the oil pipeline between the fuel tank and the engine. These pipelines need to withstand high pressure and high temperature, while also requiring good corrosion resistance and sealing properties to ensure the safe transportation and supply of fuel. In the aviation field, fuel pipelines usually use corrosion-resistant alloys, such as stainless steel, titanium alloys, etc. Alloy tubes are used between the fuel filter and the fuel pump to deliver filtered fuel to the engine combustion chamber. These connecting pipes need to have good corrosion resistance and sealing properties to prevent fuel leakage and system failure.

Fuel sensor connection: In the fuel system, alloy tubes are used to connect fuel sensors, such as oil level sensors and pressure sensors, to monitor the status of the fuel system and provide corresponding feedback signals. These pipes need to have good corrosion resistance and mechanical strength to ensure sensor accuracy and reliability. In aircraft engines, fuel injectors are used to inject fuel into the combustion chamber for combustion. Alloy tubes are used to construct fuel pipes for injectors, and their high-temperature and high-pressure working environments require excellent heat resistance and corrosion resistance. Valve bodies and connections in fuel systems also require the use of alloy materials to ensure they have sufficient strength and corrosion resistance. These components need to withstand frequent stress and movement, so the high strength and durability of alloy pipes make them an ideal choice.

Structural components: Alloy tubes are also used to construct structural components of aircraft and spacecraft, such as support structures, frames, etc. These pipes need to be high-strength and lightweight to meet the stringent weight requirements of aerospace vehicles while maintaining adequate structural strength and stability.

Cooling system: In aerospace engines and spacecraft, alloy tubes are used to build cooling systems to keep the operating temperatures of engines and other critical components within control. These pipes need to be resistant to high temperatures, pressure, and good thermal conductivity to ensure efficient operation of the system.

Propulsion Systems: Alloy tubes are also used to construct propulsion systems, such as propulsion ducts for rocket engines. These pipes need to withstand extreme temperatures and pressures and have a high degree of corrosion resistance and thermal stability to ensure propulsion system reliability and performance.

In-cabin piping: In the cabins of aircraft and spacecraft, alloy tubes are used to transport air, water and other fluids to meet the living needs of passengers and crew. These pipes need to have good sealing, corrosion resistance and high temperature resistance to ensure the safety and comfort of the cabin environment.
