Abstract: This work presents a comprehensive electrochemical
corrosion analysis conducted on steel coated with glass-reinforced
polymer (GRP), low alloy steel and stainless steel, focusing on their
performance in a simulated aggressive environment (3 % NaCl). The
corrosion rates were established and the corrosion mechanisms governing
each material's behaviour were elucidated. By comparing the
electrochemical behaviour of these materials, we aim to evaluate the
efficacy of GRP coatings in preventing corrosion compared to
conventional metallic materials used for pipeline systems. Furthermore,
in addition to the corrosion analysis, the coefficient of friction
determination between the GRP-coated steel and 25CrMo4 (EN 10083-3)
steel was conducted to assess their tribological compatibility.
Understanding the frictional behaviour between these materials is
essential for optimising pipeline performance, minimising wear and
ensuring operational efficiency in dynamic environments encountered in
the petroleum and gas industry. The study includes, also, an evaluation
of cumulative linear wear to quantify the material loss. This
comprehensive approach provides a complete understanding of the
interplay between corrosion resistance and mechanical durability.
Keywords: GRP coating, steel, corrosion rate, coefficient of friction, wear.
