Carbon steel should be included as the base case of any hydrocarbon pipeline systems materials selection exercise, k is important that all relevant corrosion management issues are adequately addressed at each stage of the business cycle, to facilitate the safe and cost-effective selection and use of carbon steel as a pipeline material. The materials and corrosion engineer has a key role to play in a multi-disciplined team with the design engineers, to ensure that the corrosion risks are adequately addressed during the design stage. The constraints applied by the materials and corrosion engineer at the design stage must be fully appreciated by staff later involved in operating an installation. Equally the maximum benefits should be taken of corrosion monitoring and inspection data in the day to day operation of equipment for ensuring technical integrity at minimum cost as long as it is required.
