history, causes, and mitigation

خوردگی ترک تنشی بر روی خطوط انتقال گاز :

تاریخچه، علل ایجاد و راه های کاهش خطرات

ABSTRACT

This paper reviews the historical data concerning external stress-corrosion  cracking (SCC) of gas transmission pipelines as it has evolved since 1965 and the factors controlling such SCC (eg, pipe environment, steel, and operation). Discussion of these Factors leads to identification of ways in which this cracking can be controlled / mitigated – in the practical setting of an operating pipeline that is expected to provide a reasonable return on equity.
