Welcome!
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 water pipe shall be firmly bound with the reinforcement framework or erected reinforcement to prevent water blockage or leakage due to deformation or joint detachment of the water pipe during concrete pouring. After the installation of the water pipe network, connect the inlet and outlet pipe orifices with the inlet and outlet main pipes and water pumps for a water connection test. The water pipes are required to be smooth and free of water leakage.
