V = pi r squared times height so figure about 3 times 18 squared times 36 thats about 35K cubic inches if solid, or 2 inch thick walls means subtract 3 times 14 squared times 35 thats about 21K cubic inches. So a good 14K cubic inches of stainless. Engineering rule of thumb to one sig fig (I mean we are assuming pi=3) is stainless is about a quarter of a pound per cu inch, so that pipe weighed about 3500 pounds. A good engineer should be able to do all this in his head; to one sig fig that pipe weighed about as much as a lightweight F-150 pickup truck (not the extended bed super crew cab LOL thats probably 5000 pounds)
World record squat lift was 1036 pounds as I recall. LOL No not my record, my heaviest set on Friday was 480 and 8 reps.
At the time, I could lift one end of an upright piano in the sense of getting both wheels off the floor.
I had never experienced the sense of utter futility before trying to lift that pipe. The complete and overwhelming sense that I would never be able to make it move even 1mm off the floor.
