"Web18 May 2024 · Even in cases where it is easy to re-round the pipe, damage can occur. Re-rounding the pipe cross section can induce a bending stress, weakening the pipe and making it more susceptible to oval again, and even collapse under stress. Early detection and correction of excessive ovality is paramount in ensuring long term pipeline safety. " - Thickness reduce in bending pipe
