The type of media conditions that cause ammonia induced stress corrosion cracking on the vapor side of copper alloy cooling pipes is also the type of media conditions that cause condensate corrosion, which is limited to air cooling areas with high concentrations of oxygen and ammonia. At the same time, in the presence of oxygen, spherical condensate corrosion trenches will be formed on copper alloy pipes. When the tightness of the vacuum system is poor, the oxygen content in the steam side of the condenser increases, and the corrosion strength of oxygen in the condensed water is not inferior to that of ammonia.

The cooling pipe is composed of curved metal pipes, installed in liquid, and is an important part of power equipment. The exhaust gas generated by the operation of the power system can reduce the temperature through the cooling pipe. It can be divided into metal and plastic, suitable for machine tools, hydraulic machinery, CNC machine tools for oil and water cooling systems.
