Hi Thomas
yes I am sort of. Its for a pipeline that will be built soon. I want to be sure that the selected pipe material/surface treatment is suitable fror a 20 year life.
The coated steel options will be the tricky ones to estimate life, but may be the cheapest.

Cheers

Steve

are you concerned with corrosion rates as a function of Langlier Saturation Index?
