Failure Pressure Analysis of Corroded Pipelines with Spherical Corrosion Pit

تحلیل فشار شکست خطوط لوله خورده شده با خوردگی حفره ای کروی-Corrosion pits were investigated by finite element method. Effects of internal pressure, radius, depth and spacing of corrosion pits on failure pressure of corroded pipeline were discussed. The results show that failure pressure of corroded pipeline with spherical corrosion pit obtained by FEM is bigger than by ASME B31G . ...
