The Effects of Sour Candy

The Minnesota Dental Association has started a campaign to combat the effects of acidic drinks and candies on tooth corrosion. They've compiled a chart of listing several popular sour candies, some of which are more acidic than battery acid. More details here.

St. Louis Gateway Arch Showing Rust and Decay

Almost 45 years into its reign atop the St. Louis skyline, the 630-foot monument is suffering from growing rust and decay. And nobody knows how extensive. Corrosion, some of it feared aggressive, and severe discoloration of the stainless steel skin have long been present, according to engineering reports reviewed by the Post-Dispatch. ... The problems are increasingly evident, with streaks and spots marking the upper reaches of the Arch exterior.

US Department of Defense Corrosion Defense website

The DoD Corrosion Defense (CorrDefense) Web Site is a state-of-the-art corrosion prevention and control information management and distribution e-portal sponsored by the Office of the Under Secretary of Defense for Acquisition Technology and Logistics (OUSD(AT&L)), Office of Corrosion Policy and Oversight. The website has been designated as one of the cornerstones in the DoD's long-term strategy for corrosion prevention and mitigation detailed in 10 U.S.C. 2228, which was enacted by the Bob Stump National Defense Authorization Act for FY 2003. CorrDefense is a free service for all individuals and organizations from Industry, Academia, and Government who have an interest in corrosion, particularly as it relates to DoD weapon systems, equipment, related commercial assets, and infrastructure.

ECDA For Cased Pipelines

From Pipeline and Gas Journal article "Mears Hosts Workshop On ECDA For Cased Pipelines":

Fifty-six integrity representatives from pipeline and gas utility companies across North America attended the day-long event at Mears headquarters in Rosebush, MI. Speakers included Max Kieba, Central Engineer, Office of Pipeline Safety, who gave directions to attendees on the upcoming PHMSA cased-pipe guidelines. Demonstrations included field indirect and direct inspections of coated and uncoated cased pipe, and a demonstration of wax filling a casing by Royston.

Casings are a common historical practice to prevent overburden stresses and mechanical damage to pipelines, typically at crossings, but they cause some unique problems with cathodic protection and corrosion surveys. Uncased crossings are usually preferable to cased crossings from a corrosion point-of-view. The NACE Standard SP0200 "Steel-Cased Pipeline Practices" (PDF, 833k, free to NACE members $35 for non-members) says:

1.2 Use of cased crossings should be avoided unless required by load considerations, unstable soil conditions, or when their use is dictated by sound engineering practices.

The issue has become critical in the gas transmission industry with the requirements of the Gas IMP rule and the limitations of performing ECDA on cased crossings. There was a PHMSA public meeting in July 2008 to address all the issues of cased crossings. There is more information on the PHMSA meeting website. In particular, this presentation from a liquid operator gives an overall perspective on the issues of casings.

The author also recently participated in an article in the March 2009 Pipeline and Gas Journal titled "Protecting Pipelines At Crossings: Are Casings Obsolete?".

Current and Future Corrosion Challenges

The chemical, refinery, and petrochemical industries are facing new challenges in order to develop more environment friendly processes and to manufacture "green" products. Corrosion management is an essential element for the development of a sustainable industrial society, including issues such as the selection and development of corrosion resistant materials, coatings, and environmentally friendly inhibitors.
