Critical Issues on Cast Iron Pipelines

Abstract

Cast iron pipelines are still utilized for water and gas transportation. Recently several dangerous events occurred. Thus the study of both endogenous and exogenous critical issues on cast-iron pipelines is again of interest.Those critical issues have been analyzed, also considering some actual cases. Experimental results, obtained from tests performed on lamellar cast iron coming from pipes broken in works, have been reported. Particularly toughness, crack growth rate and UTS have been determined by considering also the defectiveness and corrosion conditions of the studied material. A system for cast iron pipelines monitoring is proposed.
