Abstract

methodolo ies. st, through weight loss method and
secondly, % y potentio ynamic and potentlostatic electrochemical
methods. The corroding media have been selected based on the
expected environments that a pipeline in the petroleum industry
can possibly meet.These environments are mainly restricted into
two main types of corrodants, namely, saline water with different
concentrations and acidic solution of about 0.1M HC1. The
results show that it is possible to rely on the accelerated
electrochemical methods in order to predict the durability of the
coating material against different corroding media. The study also reveals that some pes of epoxy resins are superior in
corrosion protection an a durability against saline water and
acidic corrosive media as compared to the others.
