Reference answers: (1) It should possess good mechanical properties at the operating temperature, namely high strength, good plasticity and impact toughness, as well as low notch sensitivity. (2) It needs to have good resistance to corrosion by gases such as hydrogen and nitrogen. (3) It should have good manufacturability and workability, along with excellent weldability. (4) Good thermal stability.
The most critical issue is likely corrosion; the internals of packed towers are generally made of stainless steel.

Good mechanical properties at the operating temperature, namely high strength, good plasticity and impact toughness, as well as low notch sensitivity. 2. It is required to have good resistance to corrosion by gases such as hydrogen and nitrogen. 3. It is required to have good manufacturability and workability, as well as excellent weldability. 4. Good thermal stability. As a side note, the answer is concise, but what exactly is going on, and why are such requirements and rules in place? Please ask the moderator to explain in detail! I only know what it is, but not why!
1. Operating conditions of the container, such as pressure, temperature, and medium. 2. Mechanical properties of the material. 3. Corrosion resistance of the material. 4. Processability of the material as well as its price, etc
The hidden function seems to be disabled?? Consider the following: 1. Operating conditions such as pressure, temperature, and medium; 2. Mechanical properties of the material; 3. Corrosion resistance of the material; 4. Workability of the material and its cost
1. The material should be selected based on the properties of the material to be purified (whether it is a corrosive or non-corrosive solution, and whether the material has high or low viscosity). 2. The operating temperature and pressure resistance of the material should be determined according to the operating conditions. 3. It is also necessary to determine the standards for the selected materials ； 4. Final determination of material prices
The properties of the process medium, such as viscosity, hydrodynamic characteristics, and corrosivity, are constraints on the materials used for tower equipment； The tower height and diameter also impose requirements on the tower structure ； The packing material for packed towers is also subject to restrictions ； Cost is also a factor that influences material selection.
