Large Diameter Steel Plant Main and Fittings

[tonyfahres]

Good day! I feel bad that my first official post on this forum is a question not an answer, but I am looking for help if anyone can give it. I am working on a project installing valves in water treatment plant piping, and I am having trouble finding the needed parts for the steel water main portions. Does anyone have any recommendations on manufacturers who can produce steel piping and fittings for 60" and 84" diameters? If there is any published information about laying lengths I would be doubly grateful.
Thanks!

I am in the process of ripping out 250ft of 18" spiral welded steel pipe that thinks it is a sprinkler system.

I would steer clear of this garbage.
