Title: The Measurement of Hardness and Elastic Modulus of non-Metallic Inclusions in Steely Welding JointsAuthors: Ignatova Anna, Ignatov Mikhail. Abstract: Trunk pipelines work under a cyclic dynamical mechanical load because when oil or gas is pumped, the pressure constantly changes - pulsates. Therefore, the fatigue phenomenon is a common reason of accidents. The fatigue phenomenon more often happens in the zone of non-metallic inclusions concentration. To know how the characteristics of non-metallic inclusions influence the probability of an accident the most modern research methods should be used. Keywords – pipeline, non-metallic inclusions, reliability, fatigue, hardness, shrinkage, nano-indentation. |
