Abstract
“Development of different coating systems for protecting steel pipelines from corrosion in different media”
In this work, different coatings were prepared for the corrosion protection of steel pipelines encountered in the oil and gas industry. The main stream is improving the basic components of functional coatings (binder and pigment) and creating new coating systems which can withstand efficiently in the severe corrosive media.
The generated binder systems were based on both water-based system (Acrylic emulsion), oil-based systems (epoxy and polyurethane) and their combinations. On the other hand, novel pigments were prepared based on the combination of different metals to produce new trend of eco-friendly cheap anticorrosive pigments. Two pigments were prepared by the combination of cobalt, zinc and different sources of aluminum (bauxite ore and aluminum foil waste), i.e. natural ore and waste. The two prepared pigments and the generated binders were first characterized and then incorporated in different coating formulations. These formulations were tested for evaluating their mechanical properties (adhesion, impact resistance, ductility and hardness) and also their anticorrosive activity against different media (CO2, NaCl, HCl and H2SO4) using electrochemical measurements and immersion test.
