Abstract: The paper presents computation technology for numerical analysis of multiaxial non-linear stress state of the corroded pipeline segments. Developed computation technology along with the modern In-Line Inspection (ILI) tools gives an opportunity for the transport company experts to predict the high accuracy values of burst and safe maximum pressures of the corroded pipeline segments. It allows a decrease in accidents, to provide maximal economical effectiveness of technical inspection and repair of pipeline networks. Moreover, wide application of computation technology allows to make recommendations to the technical inspection tool companies for improvement of technical specifications of their products.

Keywords: pipeline corrosion; in-line inspection; computational technology; strength; measurement errors; multiaxial nonlinear stress; pipeline safety; corrosion defects; numerical simulation; nondestructive testing; NDT.
