Abstract

The effect of yield-to-tensile strength ratio (Y/T) on failure pressure of X70 pipeline without and with corrosion defects was investigated. The stress-strain response of materials was characterized by a power-law hardening curve. Two formulas to estimate the strain hardening exponent n for a special Y/T were obtained by least squared regression method and the influence of Y/T on n was analyzed. As an application of n-Y/T expression, the analytical solutions of burst pressure for X70 pipeline without and with corrosion defects were also obtained. The results indicate that the burst pressure of defect-free X70 pipe without corrosion defects is a function of the Y/T, pipe geometry t 0/D 0 and engineering tensile strength, and increases as Y/T or t 0/D 0 increases; whilst the burst pressure of corroded X70 pipe decreases with the increase of defect depths, d/t. Comparisons indicate that the present analytical solutions closely match available experimental and numerical data.
