The utility protects in use, wet
pipeline with an anti-corrosive, water
based, ceramic coating with no VOCs
or HAPs
When an electric utility in the
Southeastern United States sought
to protect above ground natural
gas pipeline against corrosion, the
goal was to cost effectively do so
while minimizing downtime and
environmental impact.
Yet in the power and petrochemical
industries, protecting above
ground pipeline from corrosion
can be a challenge, particularly
when the pipeline carries a cooled
compressed gas that draws
moisture out of a hot or humid
external environment. This causes
in use pipeline to continuously drip
water, or “sweat”, making adhering
a protective coating to the exterior
of the pipeline virtually impossible
without shutting down the line.
Traditional organic coatings also
typically require days or even weeks
of facility downtime depending on
the project, due to complex surface
preparation and application as well
as curing times needed between
coats. This can be tremendously
expensive in terms of lost
production as well as shut down and
start up costs.
Utilizing such coatings near people
or sensitive areas can also be
problematic because they typically
involve dangerous Volatile Organic
