Using the Mathematical Criterion of Gas Pipeline Failure to Determine the Remaining Operation Life

“…Features of operation and reliability of pipelines transporting hydrogen sulfide-containing media are reflected in the works of scientists [4,5].…”

“…Diagram of the main experiments to determine the components of the surface tensor for the Goldenblatt-Kopnov strength criterion. a) в 1 + в 1 − are ultimate tensile and compressive strengths in the direction of axis 1; b) в 2 + в 2 − − ultimate tensile and compressive strengths in the direction of axis 2; c) в 45 + и в 45 − − ultimate shear strengths along areas inclined to the main ones at an angle of 45 degrees; d) в 1,2 − shear strength at the site with axes 1 and 2.In developing his criterion, K.V.Zakharov limited himself only to a coordinate system that coincides with the axes of symmetry of the mechanical properties of the material(5). Zakharov writes the strength condition for materials with different tensile and compressive strength as a second-order surface equation:…”
