Mechanical Joint vs. Flanged Joint
Mechanical Joint vs. Flanged Joint
(OP)
Does anyone have a listing of prices for mechanical and flanged joint DI piping for sizes (4"-54")... I realize that there are location adjustments, but I am just trying to get a general idea.. In general, is mechanical joint more or less expensive than flanged joint???

My preference for assebling DI water piping systems is to butt weld everything except where I need to install a a manual valve or a control valve and then it is a flanged connection.
Are you serious about DI water piping as large as 54"?

It is for local piping at a water treatment plant.. They prefer DI pipe in that size to concrete pipe...

you should get some healthy competition
If you are below ground, I would consider steel with welded joints or bell and spigot if thrust restraint is not an issue. Above ground, flanged is OK but also consider victaulic or dresser couplings.
