Determination of factors affecting on grooving corrosion

WithA.V. Kasyanov, A.E. Belousov, G.G. Popov, V.I. Bolobov

The work describes the experimental definition of the main factors that contribute to the emergence of grooving corrosion: availability of abrasive particles in flow which are transported in specific terms when they are capable of scratching the bottom generating line of a pipeline by creating stress concentrators; availability of considerable residual stresses in pipe metal; oxygen availability in reaction zone.
