What are the advantages of 304 Stainless Steel Corrugated Low Pressure Oil Pipe in high temperature environment?

304 stainless steel corrugated low-pressure oil pipes show several obvious advantages in high temperature environments, which make them an ideal choice in many high-temperature applications. The following are its specific advantages in high temperature environments:

1. High temperature resistance
304 stainless steel high temperature stability: 304 stainless steel has excellent high temperature resistance and can usually be used for a long time at temperatures up to 870°C (760°C in an oxidizing environment) without significant deformation, embrittlement or failure. This makes 304 stainless steel corrugated low-pressure oil pipes suitable for high-temperature oil delivery systems, such as engine compartments, hydraulic systems and hot oil pipelines.
Oxidation resistance: 304 stainless steel has excellent oxidation resistance in high temperature environments. Even if it is exposed to high temperatures for a long time, a stable oxide film can be formed on the surface to prevent the metal body from being oxidized and corroded.
2. Thermal expansion resistance
Low thermal expansion coefficient: 304 stainless steel has a low thermal expansion coefficient, which means that its dimensional changes in high temperature environments are relatively small. This helps to maintain the shape and structural stability of the pipeline in an environment with large temperature fluctuations, reduce the stress accumulation caused by temperature differences, and thus avoid damage or leakage of the pipeline.
Maintaining sealing: Due to the stability of 304 stainless steel when the temperature changes, the corrugated oil pipe can maintain good sealing under high temperature fluctuations to avoid leakage problems caused by expansion or contraction.
3. Thermal shock resistance
Good thermal shock resistance: 304 stainless steel is not only resistant to high temperatures, but also has strong thermal shock resistance. For some systems that frequently experience rapid temperature changes (such as during the startup and shutdown of mechanical equipment), 304 stainless steel corrugated oil pipes can withstand rapid temperature changes without cracking or breaking due to thermal shock.
4. Resistance to high temperature aging and fatigue

Resistance to high temperature aging: In high temperature environments, the chemical composition of 304 stainless steel materials is stable, and it is not easy to thermally decompose or age, and it can maintain its original mechanical properties and chemical stability for a long time.
Fatigue resistance: When 304 stainless steel corrugated oil pipes are subjected to alternating high temperature and high pressure, they can effectively resist fatigue problems caused by alternating temperature and pressure, and extend the service life of the pipeline.
5. Excellent corrosion resistance
Chemical corrosion resistance: Under high temperature conditions, 304 stainless steel has good corrosion resistance, especially when it comes into contact with oils containing acid, alkaline or other corrosive chemicals, 304 stainless steel can maintain good corrosion resistance and is not easily corroded by corrosive oils or gases.
Not easy to form deposits: The surface of 304 stainless steel corrugated oil pipe is smooth, which can effectively reduce the formation of deposits of oil or gas at high temperature, avoid pipeline blockage and performance degradation.
6. Low maintenance
Long-term high temperature operation stability: 304 stainless steel corrugated oil pipe can operate stably for a long time in high temperature environment without frequent maintenance or replacement. This makes it particularly advantageous in industrial applications because it reduces system downtime and maintenance costs caused by temperature fluctuations.
Lower maintenance cost: Due to its excellent high temperature resistance and corrosion resistance, the maintenance cost of 304 stainless steel corrugated oil pipe in high temperature environment is relatively low. Compared with other materials (such as ordinary carbon steel, aluminum pipe, etc.), it is not easy to rust or deteriorate, thereby extending its service life.
7. Flexibility and adaptability at high temperatures
Flexibility of the corrugated structure: The corrugated design of the 304 stainless steel corrugated oil pipe makes it more flexible and adaptable. Even in high temperature environments, the bellows can effectively alleviate the thermal expansion and vibration of the pipeline, avoiding rupture or leakage caused by uneven force.
Adapt to different temperature changes: The design of the bellows also enables it to adapt to pressure fluctuations and mechanical vibrations at different temperatures, and is particularly suitable for systems with frequent temperature changes or that require flexible connections.

These advantages make 304 stainless steel corrugated low-pressure oil pipes widely used in hydraulic systems, engine compartments, hot oil pipelines and other fields under high temperature and complex working environments, and are a very reliable and efficient pipeline choice.
