Methodology of Analyzing the Causes of Accidental Failure of Pipes Made of Various Steel Grades

Аннотация

The statistics of the emergency of gas lines induced by stress corrosion cracking (SCC) is presented. A model is proposed to study accidental failure, and a method is suggested to estimate the behavior of steels under complex line conditions and to choose SCC-resistant steel grades for the line sections that are susceptible to SCC.
