Corrosive and Mechanical Degradation of Pipelines in Acid Soils

The effect of in-service degradation on the deformation behavior of the material of gas mains in soil acid electrolytes has been studied, and it has been shown that depending on the concentration of the corrosive components of the environment, the strain increment can be up to 20–30%. It has been fo...

Description
Summary:The effect of in-service degradation on the deformation behavior of the material of gas mains in soil acid electrolytes has been studied, and it has been shown that depending on the concentration of the corrosive components of the environment, the strain increment can be up to 20–30%. It has been found that in soil acid electrolytes, degraded pipeline steel shows a tendency to sudden strain jumps, which can cause spontaneous depressurization of the pipeline. Исследовано влияние эксплуатационной деградации на деформационное поведение материала магистральных газопроводов в кислых грунтовых электролитах и показано, что в зависимости от концентрации коррозионных компонентов среды прирост деформации может составлять до 20 30%. Установлено, что в кислых грунтовых электролитах деградированная трубопроводная сталь имеет склонность к внезапным деформационным скачкам, которые могут вызвать спонтанную разгерметизацию трубопровода.
