About the types of nitrogen
Thread Content
What are the differences in the components of N2 and N3? In what specific areas is it used?
Sir, do you think everyone knows what N2 and N3 are that you’re talking about? A parameter is needed to say that. Trying to make people understand what a symbol means just by showing it is a real test of one’s intelligence.
The purity of nitrogen is 2 nines and 3 nines respectively
Oh, I heard about it for the first time; I thought it was something like O2 O3
It is mainly the difference in impurity content. Different requirements apply depending on the end-use
Apart from the difference in purity, it is mainly the pressure rating that differs.
