explains Merrick Alpert,” President of EonCoat. “This
‘self heals’ the breach, depending on its size, and
stops the corrosion if necessary.
This capability, along with the coating’s other
properties, enables effective corrosion protection for
the life of the asset with a single application.”
Easy Application, Environmental Benefits
In the electric utility pipeline project, water jetting
the pipeline’s exterior was sufficient to clean and
prepare the surface for coating, since only a NACE
3 / SSPC-SP 6 /WJ-1 commercial blast cleaning is
needed.
The CBPC coating was successfully applied to the
exterior of the ‘sweating’ in use natural gas pipeline
outside the facility when atmospheric temperature
was 87 °F with 58% humidity.
Such CBPC coatings consist of two non-hazardous
components that do not interact until applied by a
standard industrial plural spray system like those
commonly used to apply polyurethane foam or
polyurea coatings.
While EonCoat is normally spray applied at a
thickness of 20 mils before a topcoat is applied, in
this case the CBPC coating was deliberately applied
at 25 mils and no topcoat was used to deter mold
growth on the pipeline’s exterior. The high pH of
the inorganic coating tends to retard mold growth
when used without a topcoat, even in a hot, humid
environment.
Because of the ceramic coating’s multiple layers of
corrosion protection, and the ability to “self heal”
breaches, the power plant is on track to see long term
protection of its pipeline, effectively eliminating the
traditional cycle of blasting and recoating during
costly shutdowns.
