Corrosion  Get seen by the people that USE your products THIS SPACE can be yours

Corrosion is a subject that any Instrument Engineer should have knowledge in as selecting the correct equipment and process instruments for a plant is dependant on it. This page provides some excellent technical information about corrosion, forms of corrosion, corrosion effects, how to mitigate corrosion and corrosion monitoring and control. In addition there are Material Selection Guidelines and Corrosion Tables.

Selecting Fluid System Components for use in Sour Oilfields - The conditions under which oil and gas are brought from their reservoirs to the surface can be outright hostile to many common materials used in fluid system components employed in industry. Potentially dangerous mechanisms include localised corrosion, stress corrosion cracking (SCC) and sulphide stress cracking (SSC). SSC has become increasingly common as more sour reservoirs are being developed - for example, those in the northern part of the Caspian Sea that contain up to 20% hydrogen sulphide (H₂S). Ageing reservoirs can also turn sour as abiotic and biotic reactions take place. This article describes how to select the optimal materials of construction for components that need to perform reliably for many years in the demanding sour environments of oil and gas exploration and production - from Process Online and Swagelok.
Real-Time Corrosion Monitoring - Integrating Corrosion Data with other Process Variables - Russell Kane and Keith Briegel - Existing programs on the control system can assess, identify key plant relationships - The petrochemicals and pharmaceuticals sectors spend $2.5 billion annually to combat corrosion. Worldwide, the cost of corrosion in the process industries appears to be about $50 billion per year and will probably climb higher over the next five years. Many operators currently see corrosion on a “straight-line basis” in terms of repair, maintenance, and replacement during fixed interval turnaround inspections. New technology, however, is available that assesses corrosion deterioration in real time using the plant control and automation system. This makes linking corrosion to process conditions more direct and immediate. It also allows the assessment of corrosion in much shorter time intervals with the ability to control and mitigate the rate of damage and more accurately factor in its true economic impact on plant operations - from ISA and InTech.
3.12 Corrosion Monitoring: Breaking down the Misconceptions -Sridhar Srinivasan - The latest technology links corrosion to process conditions more directly and immediately. It also allows corrosion depreciation to be assessed in much shorter time intervals with the ability to control and mitigate the rate of damage and more accurately factor in its true economic impact on plant operations - from www.processonline.com.au
