The general principles for classifying according to the equipment section are: 1. Temperature; 2. Whether oxygen is present in addition to hydrogen sulfide； 3. Is it possible to experience dew point corrosion caused by sulfur dioxide, etc.? This is a rather broad topic. However, for the pipes in sulfur recovery units, since there is no oxygen present in the system, carbon steel is generally sufficient. But in the quenching section, where there is a risk of sulfur dioxide penetrating, it is recommended to use stainless steel
