IN THIS ISSUE
CORROSION PREVENTION AND CONTROL WORLDWIDE MATERIALS PERFORMANCE
This month, MP offers several articles that fulfill the duel
editorial themes of oil and gas pipeline corrosion and the
impact of corrosion on the environment. The technical
article beginning on p. 32 describes the conventional
understanding of how cathodic protection works and
an alternative view of the mechanism as it relates to
buried pipelines. See p. 48 for an article that addresses
calcium carbonate (CaCO
3
) scale formation and inhibition
during enhanced oil recovery. The Material Matters
article beginning on p. 14 discusses a research project
between four Canadian universities on microbiologically
influenced corrosion of pipelines. Among articles focused
on environmental impacts of corrosion is the Coatings
& Linings Essentials article on p. 43 on how to prevent
power plant leaks. Finally, MP has a new monthly feature
beginning this month on NACE International's Strategic
Plan, including the planning process, the goals and
components, and how you can become involved (p. 64).
