Taking Corrosion To Extremes In Brazil Managing corrosion in new territories and extreme environments is an area in which the industry is struggling because we don’t understand the challenge of these environments.

A lot of R&D work is being done to replicate these extreme conditions in the laboratory and the findings will be of great assistance, especially in relation to issues around Brazil’s pre-salt layer.

It contains impurities such as nitrogen oxides (NOx) and sulphur oxides (SOx) which are produced particularly from coal-fired power stations.

To bring the impurities down to levels below which they have a negligible effect on corrosion is not currently cost-effective.

Financial Argument For Lifecycle Management High-performance corrosion-resistant alloys are certainly available, but they are expensive and unlikely to make an immediate, significant impact on the enormous preponderance of carbon steel pipelines, which account for 90% of the world’s stock.

These new alloys combine the strength of steel with the resilience of lining and, in an ideal situation, businesses would make increasing use of them as part of an effective lifecycle management program.

In some cases, costings can show that higher initial investment in better materials and technology can greatly reduce operational maintenance, and hence reduce overall costs over a project’s lifetime.There are significant business benefits but sadly, many people simply aren’t aware of them.Short-termism and the culture of instant returns is a serious problem.The country has exploited its vast natural resources and huge labor pool to become Latin America’s leading economic power and the discovery of several extensive gas fields in the pre-salt layer has opened a new chapter of growth opportunities.I was in Brazil in September when I delivered a paper titled, “Pre-Salt Compliance With International Standards for New Corrosive Environments” at Rio Oil & Gas 2012, an event supported by UK Trade and Investment Brazil.
