NACE International Tackles Corrosion Costs of $5.4 Billion for Gas and Liquid Transmission Pipelines

Published on 2008-12-26. Author : SpecialChem

HOUSTON, TX -- A recently completed NACE International Corrosion Technology Gap Analysis identifies products and services needed to reduce corrosion costs for the gas and liquid transmission pipeline industry. With nearly 500,000 miles of pipelines in use in the United States, the report stated that the cost of replacing and maintaining these pipelines is estimated at $1.1 million per mile. The costs associated with corrosion-related failures (25% of all accidents), capital investment for repairs, and system maintenance is estimated at $5.4 to $8.6 billion a year. NACE is addressing these findings through the publication of standards and the development of courses and events for the pipeline industry. Among the technology gaps identified were the need to understand how various factors influence corrosion and integrity, how to better detect the onset and extent of corrosion, and how to improve the overall education, training, and public awareness of the influence of corrosion.

NACE has published a series of standards on the direct assessment process, a four-step process to study the history and operating conditions of a pipeline and predict where corrosion is most likely to occur. NACE SP0502-2008 on external corrosion direct assessment has been incorporated by the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) in U.S. pipeline safety regulations. Other NACE standards under consideration by the PHMSA include SP0204-2008 on stress corrosion cracking (SCC) direct assessment, SP0206-2006 on internal corrosion direct assessment for dry gas pipelines, and SP0208-2008 on internal corrosion direct assessment for liquid petroleum pipelines. Specialized training offered by NACE for the pipeline industry includes NACE Operator Qualification (OQ), Internal Corrosion for Pipelines, and Pipeline Corrosion Integrity Management (PCIM). These programs were designed to provide individuals with limited to intermediate pipeline corrosion work experience with the knowledge to perform a range of skills, from basic OQ-covered tasks to maintaining an internal corrosion control system to implementing a pipeline integrity program.

NACE continues to educate the industry and the public on new technologies and applications of the direct assessment process through its External Corrosion Direct Assessment Seminars, with one upcoming in January 2009.

With the significant economic impact of pipeline corrosion in the U.S., NACE International is dedicated to providing corrosion solutions that bridge the technology gaps in the gas and liquid transmission pipeline sector.
