CeRam-Kote PCF is a thin-film, spray applied ceramic
epoxy coating engineered to provide excellent chemical
resistance and corrosion protection to Oil Country
Tubular Goods. CeRam-Kote PCF is a highly modified
novalac epoxy resin system that has been heavily loaded
with a unique package of ceramic particles enhancing its
ability to perform well in a variety of aggressive
environments. The formula is highly cross-linked to
provide chemical resistance.
Acidizing Fluids
If well fluids are not hot and stimulation fluids are
charged through the coated tubing in a short period of
time, there is generally little effect if the fluids are
flushed completely through the tubulars. However,
some organic acids and solvents may have a detrimental
effect on certain organic coating systems, especially as
temperatures increase. If stimulation fluids are left in
the tubing, they can reach formation temperature and
cause accelerated attack on the coating. A Freecom
Technical Representative should be consulted when
acidizing is contemplated.
