Although intergranular stress corrosion cracking (IGSCC) of high-pressure gas pipelines has been known for more than 20 years, a transgranular form (TGSCC) was detected more recently. Instances of TGSCC have been associated with dilute solutions with pH values in the region of 6.5 because of the presence of carbon dioxide (CO 2 .
1/1/2017· Corrosion management for high pressure high temperature (HPHT) oil and gas fields is a challenging task due to limited knowledge on corrosion behavior in hostile conditions. In this chapter, we provide some recent developments on corrosion and scale studies at HPHT conditions.
