If only the medium factors are considered, does the shell side of this heat exchanger require heat treatment?

Question: In a floating-head heat exchanger, the fluid flowing in the shell side is liquefied petroleum gas. Considering only the properties of this fluid, is it necessary to perform heat treatment on the shell side of this heat exchanger?
:Q doesn’t know. . . I guess a safety valve needs to be added:o
Does it contain H2S? ? Be careful of stress corrosion; heat treatment should be considered
Do you mean that heat treatment is not necessary if the H2S level is below 100 mg/L, or is heat treatment required regardless of the level?
Specifically, it depends on the tolerance specifications – there are a total of 4 conditions. If these conditions are met, then measures such as controlling the materials, managing welding processes, increasing the frequency of inspections, and adding heat treatment steps are required. It’s necessary to check the tolerance specifications in detail~
