Here is the long answer...take 1.9 in od pipe .145 wall r is. 626
For ASD...the easy stuff
KL/r is 1*48/.626 is 76.67 which is less than 200 so it is not slender
Cc is sqrt((2*pi^2*E/Fy) is 126
Fa is ( (1-(76.67)^2 / (2*126^2))*36)/(5/3 + ((3*76.67)/(8*126)) - ((76.67^3)/(8*126^3))
Equals 15.71 ksi * .75in^2 is about 12k!
Got it? Lol
Read up in AISC ASD Chapter E.
So...there is way more to it than just critical buckling load....this does not buckle before it is overstressed so to speak...plenty of safety factor in there.
Got to go back work....was on phone...sorry about the typing...but my dick does feel bigger now.
