Anyone have any historical data or experience with how long sch 40 steel piping typically lasts outside when filled with brackish (somewhat salty) water?
I have an industrial project where the client wants to reuse some decommissioned existing 16" sch 40 painted steel product piping as their new fire water main. It would be nice to do this, because they need about one mile of fire main 12" or larger and this line is already there, in place, and currently unused. The water supply is the Saint Johns river (vertical turbine pump on a dock), which is normally fresh water but it's brackish at this site - which is about 6-7 miles from the ocean and gets a good amount of salinity with the tides. Does anyone have a feel for how long steel pipe will last in this type of application? It will be normally wet and filled entirely with water. It will likely only be flowed annually with their yearly testing. Thanks in advance for the insights, Steve Kowkabany, P.E.
