What grade of steel does 20Ⅱ refer to in the material design for ammonia pipelines? Thank you, fellow sailors------------
First, 20Ⅱ refers to 20# steel, grade 2 forgings. Second, is it appropriate to use carbon steel pipes for ammonia media?
I just checked – anhydrous ammonia can be handled using carbon steel materials.
Well, gaseous ammonia is highly soluble in water, so it should be free of water.
