Thread: Black iron pipe for cooling tower lines

I'm in real estate and am wondering how long black iron pipes last when used for cooling tower water supply and return?

Bill,

I guess that would be a function of the chemical make up of the water.

I used to live down there, what building where? How old?

The building was built in the late 70's and fully sold out in 81. The building is America's on the Park, 777 Bayshore Drive, Fort Lauderdale. We have had several "experts" give different opinions. 1. all lines need to be replaced. 2. After X-raying the different lines, only slight deteriation was detected. I am trying to advise buyers as to the condition of these lines.
Thanks,
Bill

Bill,

I can't place that building, but Bayshore Drive is on the beach side between Sunrise Blvd and E Las Olas Blvd, as I recall?

Anyway, unless there is evidence to the contrary, I would go with 1. if my neck was on the line.

If I was being brought in to determine whether 1. needed to be done or not, and 2. was performed at many locations (at many levels) and the engineering company which did the X-ray was backing a statement that replacement was not needed, then I would advise my client to make sure the engineering companies insurance was up to date for replacing the lines should they be wrong, and if the engineering company said the x-ray showed little deterioration but is not backing a statement that the pipes do not need to be replaced ... that is enough of a statement to tell me they do need to be replaced.

The other options would be to: 1) shut the piping down and run cameras inside various areas; 2) remove some sections of piping and take a look-see.

Thank you. I like your idea of removing a section for inspection.
