Weird. This plant closed years ago. What's it still doing in there?
In my younger days I worked for a mechanical contractor in Burlington. We did a job in that building replacing titanium and stainless steel piping that the cranberry juice ate holes through!! Mostly on 90 and 45 degree turns and "T" junctions where the "sludge" would sit
I'm no expert but if the pipe wore at those locations it sounds like it may have been from something abrasive in the juice and not acidity.
On another note, I like cranberry juice but I especially like it mixed with other juices (grape, apple, raspberry, etc.) or vodka.
