Our Pipelines Should Undergo the Yielding Test

The article deals in general with the process, purpose and significance of developing pipeline yielding test, the mechanism of overcoming defects in Such test, the impact of it upon the deformation of pipelines, the mechanical properties of piping and the elimination of residual stress as a result of welding, and finally the technical and economical efficiency. It ends by a auggestion that the yielding test be taken at home and how to determine the operating stress.
