API 5CT N80 CASING PIPE

There is two types for API 5CT N80 oilfield casing pipes: N80-1 and N80-Q types, which have the same chemical composition and mechanical attributes while just various in the heat treatment. N801 steel pipe is treated by normalizing and tempering and N80Q is treated by quenching and tempering. The collapsing strength and internal pressure strength of N80Q are higher than that of N801 correspondingly.
