If I recall correctly, a few weeks ago, someone posted something about
anchor rods failing in the vicinity of a pipeline, and having to do with
increasing galvanic action, cathodic potentials, sacrificial anodes and
the like. A large natural gas pipeline will be going thru the back of the
my 80 acres (whether I like it or not) but I wish to be as informed as
possible as to any disadvantages it may bring.
I currently have one tower which is guyed into the proposed right of way -
and fully expect that will be converted into a self supporting tower,
which we are negotiating about currently.
My main question is: what is the sphere of influence of a cathodic
protection system? Do I need to be concerned about other guyed towers
that are 500 feet away? 1000 feet away? I realize more facts may be needed
to give a definitive answer but for now this is all I have. This is a
significant (36 inch), nearly 2000 mile long pipeline. The soil is rather
average black dirt, certainly not particularily acidic or alkili.
Any thoughts, suggestions or additional references would be welcome.
