Purpose – The purpose of this study is to develop a new classification system for corrosive soils by considering the most effective factors of metal corrosion in soil environments. Design/methodology/approach – The classification is based on valuing each factor as its different range effects on soil corrosion. Finally, according to this classification, the soils with corrosion potential are divided into four major groups, including extremely, strongly, moderately and slightly corrosive. A total number of 20 soil samples were taken from Bushehr, Iran, and their corrosion potentials were evaluated. Findings – Results showed that most samples were within the slightly corrosive group, although these have high contents of soluble salts. Originality/value – The study’s findings could be insightful in mapping of corrosive lands for pipeline works.
