Compressed air pipe manufacturers understand that the resistance in pneumatic components is mainly characterized by a small pressure drop, resulting in similar temperatures at the inlet and outlet. However, there are certain parts, such as pressure reducing valves and throttling holes, where the compressed air expands significantly, causing a sharp drop in temperature. This sudden temperature change can lead to condensation or even icing near these areas. Fortunately, as the air moves further away from these shrinkage holes, its speed decreases and the temperature rises back to its original state. This increase in temperature, coupled with the drop in pressure, causes the condensate to evaporate, reducing the relative humidity.

In long capillary tubes, the temperature at the outlet can be considered equal to the ambient temperature due to friction and heat exchange. If the ambient temperature (Ta) is lower than the temperature at the capillary outlet (T1), condensation may occur, resulting in icing. To tackle this issue, compressed air pipe manufacturers employ theoretical analysis and calculation tools during the design and installation of compressed air pipelines. This approach ensures a more scientific and efficient layout of the pipe network compared to relying solely on experience. The difference between a professional and non-professional approach lies in the amount of gas and water wasted, with the former being more efficient.

Furthermore, under specific temperature and pressure conditions, the amount of water vapor in wet air is limited. When the amount of water vapor reaches its maximum content at a certain temperature, the air is considered saturated. On the other hand, when the water vapor content is below the maximum, the air is unsaturated. When unsaturated air becomes saturated, water droplets condense out, resulting in condensation. This phenomenon is commonly observed in high humidity during summer or when wet air cools under constant pressure, leading to water droplets forming on water pipes or windows during winter mornings.

Additionally, the leakage of compressed air pipes not only wastes energy but also causes operational losses, such as adverse pressure drops. Statistical analysis of compressed air systems reveals that leaks often account for 20% to 30% of the system's gas production. These leaks are primarily due to poor management and tend to increase over time, including issues like pipeline corrosion, loose pipe fittings, improper usage, and equipment leakage. Therefore, it is crucial to measure the amount of leakage at the leak to address this problem effectively.

As market demands for compressed air quality and stability continue to rise, the temperature during the pipeline process becomes a concern. Moisture in compressed air, pipe corrosion, and the presence of microorganisms can all lead to leakage, which falls short of modern enterprise management requirements. To improve the technical and management quality of gas pipelines, manufacturers advocate for the use of superior pipes, such as stainless steel, as well as better design, standardized construction, and management practices.
