    Corrosion Management: Atmospheric Corrosion Prediction of Carbon Steel

    Published: August 01, 2018
    Author(s): C.M. Lo, Department of Environmental Engineering, National Chung Hsing University, Taiwan, Republic of China; and Harbor & Marine Technology Center, Institute of Transportation, Ministry of Transportation and Communications, Taiwan, Republic of China L.H. Tsai, Harbor & Marine Technology Center, Institute of Transportation, Ministry of Transportation and Communications, Taiwan, Republic of China H.H. Lai and W.T. Wu, Department of Materials Science and Engineering, National Chung Hsing University, Taiwan, Republic of China M.D. Lin, Department of Environmental Engineering, National Chung Hsing University, Taiwan, Republic of China

    The main objective of this study was to develop a forecasting model of carbon steel corrosion rates in atmospheric exposures. The corrosion rates in the industrial and coastal zones were all higher than the corrosion rates in the rural zone. The corrosion rates...

    Corrosion Management: Ranking Pipeline Leakage Susceptibility

    Published: June 01, 2018
    Author(s): Olagoke Olabisi and Shibu Abraham, DNV-GL, Safat, Kuwait Saleh Al-Sulaiman and Amer Jarragh, Kuwait Oil Co., Ahmadi, Kuwait

    The causative circumstances for internal corrosion, external corrosion, and stress corrosion cracking phenomena may be dissimilar; but the forms of corrosion are essentially invariant. Inspection and monitoring are the two key processes by which pipeline...

    Materials Selection and Design: The Erosion-Corrosion Limits of Duplex Stainless Steels

    Published: May 01, 2018
    Author(s): Roger Francis, FNACE, RFMaterials, Glossop, Derbyshire, United Kingdom Glenn Byrne, Rolled Alloys, Temperance, Michigan, USA

    When metals are exposed to high-velocity water, there is usually a threshold velocity at which erosion-corrosion rapidly accelerates the metal loss. This velocity is high for most stainless steels (SS); but when solids are present, the threshold velocity can...
