Влияние концентрации хрома, температуры и давления CO2 на коррозионную стойкость насосно-компрессорных труб

Abstract

Проведены исследования коррозионной стойкости хромистых сталей (26ХМФА; 15Х5М; 20Х13) в условиях движущейся среды при повышенной температуре и давлении углекислого газа. Установлено, что с увеличением температуры скорость локальной коррозии исследуемых материалов уменьшается. The present work was carried out to study the CO2 corrosion resistance of steels with different chromium content (1; 5 and 13%). Corrosion tests were performed during 240 h in flow loop autoclave at different temperatures (100; 150; 200°С). Results obtained from test reveal that the corrosion rate decreases with temperature rise.
