Abstract High pH Stress Corrosion Cracking (HpHSCC) was identified in the 1960 s for the
first time and is considered to be a significant threat for buried pipelines. When certain …

Corrosion can occur on underground pipelines especially at coating defects, where metal
can be considered directly exposed to the soil, or under disbonded coatings, where the …

The susceptibility to stress corrosion cracking (SCC) of X70 pipeline steel under cathodic
protection in near-neutral pH and acidic solutions was investigated by slow-strain-rate …

The cracking failure of a new heat exchanger during first start-up operation has been
analyzed. Through the investigation of the operating history of the equipment, analysis of the …

A gathering pipeline in a gas field in Northeast China transporting mainly natural gas and
also some water and sands was welded using two 20G pipes with different wall thicknesses …

One of the main reasons for oil-field pipeline failure is groove corrosion. The residual life of
such pipelines is estimated based on defectoscopy corrosion rate—a ratio of the formed …

The determination of critical plastic strain-induced stress (σ cr) is significant to clarify the
influence of stress level on an environmental fracture. The σ cr of high strength pipeline steel …

Unscheduled shutdown often occurs in diesel hydrogenation unit due to the corrosion
leakage of heat exchanger. After a series of analyses of technological and flow processes …

In this study, the corrosion behaviors of four pipeline steels, ie, X70, X80, X100, and X120, in
acidic soil (Yingtan and Xishuangbanna), alkaline soil (Korla and Dagang), and dry sandy …

A defect that contains both dent and crack, often known as dent–crack defect, may lead to a
failure due to rupture or leak in the pipe wall. Hence, the pipeline operator becomes …
