Abstract
The influence of external factors,
temperature and flow velocity on the corrosion processes
St3 in model solutions petrochemical plant recycled water
with high salinity and hardness without open systems and
in the presence of the inhibiting composition. It was found
that an increase in temperature leads to a linear increase in
corrosion rates, and the change in circulating water flow
rate leads to the extreme nature of corrosion processes;
optimal conditions are determined. Recommended use of
cathodic inhibitors or mixed type inhibitor, in particular,
the composition "SVOD-BI" (means for controlling the
biological corrosion), which can significantly reduce the
effect of temperature and flow on the corrosion rate St3,
promotes the growth and strengthening of the oxide film
in the presence of oxygen, increases the degree of
protection of steel and preventing the formation of at its
surface carbonate-calcium deposits.
