It is acting like he has big cajones of steel, but I can see right through him.

Not a lot of wall thickness and no flange. It's already painted blue so I doubt they'll be installing flanges at this factory. I'm guessing that tiny brass section at the end is the bevel to weld to the next spool of pipe. But since it's so small, I bet this thing has a surprisingly low pressure rating. A kajillion gallons a second at 10 PSI or something.
