Ceramic selection as based coatings for corrosion prevention in oil preservation tanks

Glass frit mixtures were examined in order to select the best type of ceramic coating to protect oil pipelines and tanks. The particle size of glass frit's mixtures has been determined by laser light diffraction instrument and chemical composition analysis by X-ray fluorescence. Particle size analysis results showed the highest value was (7.0928μm) and lowest value (4.5821μm). X-ray fluorescence results illustrate the presence of many element oxides such (Al2O3, 2SiO, CaO, K2O) and other additives. Various dispersion slips have been utilized with glass frit mixtures. Melting temperatures were selected, and fixed at 700°C. The coating surface structural properties have been conducted by field emission-scanning electron microscope as well as, atomic force microscope for evaluating, comparing, choosing the best protection of crude oil and petroleum tanks from corrosion. Microscopic images showed success of two glass frit, with best homogeneity coating surface and high mechanical properties.
