N80-Q is different from N80-1 in heat treatment and the color of the coupling.
N80-Q needs to be given normalizing and tempering ( or quenching and annealing) in order to meet the requirements in API 5CT . But it is not neccessary for N80-1.
The coupling of N80-Q is painted with red green colors.
The coupling of N80-1 is painted with whole red color.
Therefore, it is very easy to tell of the N80-Q from N80-1 from the couplings
