Davis and Warschau (pipes) (212) 234-5100. Ask for dennis; They have decent prices and they cut their pipes well -- nice clean edges. They have everything you could possibly want in black steel plumbing pipes. They deliver.
If you want untreated black steel that's not threaded call Mount Vernon Iron Works. (submitted by David Schwarz)
