Corrosion Risk Assessment of Steel Gas Pipelines under Dynamic DC Interference according to In Situ Measurements

Abstract

AbstractDirect current (DC) traction systems such as a subway can cause time-resolved stray current interference in adjacent gas pipelines, leading to serious corrosion risk. It is important to evaluate risk according to the field test. In this paper, a ...Practical ApplicationsThis study proposes a corrosion risk assessment method that provides intuitive and reliable decision support for underground pipeline maintenance. Taking a natural gas pipeline along a metro line as an example, long-term monitoring ...
