Discussion on the material selection for ammonia tank
Thread Content
The operating temperature is room temperature, the operating pressure is 0.2 MPa, and the medium is ammonia water. What type of material would be suitable for use in this application?
a Ammonia water storage tank #Reply quickly here#
It depends on the water content of the ammonia; generally, 16MnR is used for liquid ammonia tanks.
Ordinary carbon steel will do. Look, aren’t those ammonia tanks in the countryside just like this?
For liquid ammonia, 16MnDR is also used; for ammonia water, it depends on the concentration.
The specific material to choose depends on the ammonia content; carbon steel will suffice. The problem is that the more expensive, the better; so choosing stainless steel is definitely a good option
Of course, save money wherever possible; if carbon steel meets the requirements, there’s no need to use stainless steel
What I mean is that there are compatibility issues between certain media and materials. In other words, some media are incompatible with certain materials; using carbon steel is fine, but stainless steel doesn’t work in such cases
Yes, the ammonia tank is used only to store ammonia; there are no other impurities present at present. From an economic perspective, if carbon steel meets the requirements, then there is really no need to use stainless steel. Thank you for your answer.
