Mr. Hodgman,
I saw your corrosion control engineer blog and wanted to
make contact concerning some pipeline corrosion issues we have in
Kentucky. I am a research scientist and geochemist at the University of
Kentucky and saw that you had an interest in this area of pipeline corrosion
that I have done some research in.
I have done some preliminary work in the Devonian Black
Shales in Kentucky where about 30-40 % of pipeline failures in our state have
occurred when the pipeline is sited in the Black Shale. There are
geochemical reasons for this, the shale contains pyrite, an iron sulfide which
oxides and forms a mild sulfuric acid, lowering the pH of groundwater and
accelerating the corrosion of any steel pipelines. The Beaumont, Ky
pipeline disaster noted this in the NTSB reports. Building anything
in organic black shales is troubling, but pipelines have the potential for
catastrophic events, so I have been trying to get some research funding
to study this problem..
If you know anyone in the eastern US who has pipelines in
black shales please pass this message on to them. I have a report out on
some severe foundation problems (heaving) in the black shales, http://kgs.uky.edu/kgsweb/olops/pub/kgs/ri18_12.pdf,
which would also extend to pipelines.
Good blog, Keep up the good work.
