무-용존산소 및 pH 8.0±0.3의 130℃ 수용액 내 탄소강과 저-합금강(1Cr-½Mo, 2¼Cr-1Mo)의 침식-부식 예비실험 (I)
A Preliminary Experiment on Erosion-Corrosion of Carbon Steel and Low-Alloy Steels((1Cr-½Mo and 2¼Cr-1Mo) in an Aqueous Solution with pH 8.0 ±0.3 and DO-Free at 130 ℃
A preliminary study on erosion-corrosion of carbon steel with ASTM specification of A106 Grade B and low-alloys with A335 P11(1Cr-½Mo) and P22(2¼Cr-1Mo) was carried under aqueous accelerating conditions of pH 8.0 ±0.3 without dissolved oxygen at 130℃ in an erosion-corrosion test loop. The weight losses on the surfaces of A 106 carbon steels appeared to be dependent upon flow rate and turbulence intensity. The weight losses on the surfaces of P11 and P22 low-alloy steels, measured after 500 hours, showed approximately half of that of A106 carbon steel.
