There was localized corrosion in most of the evaluated test conditions, confirming the importance of using laboratory techniques that allow such analysis. Localized as well as generalized corrosion kinetics decrease over time, confirming that laboratory tests...

ISO15156-3/NACE MR0175 3(1) is generally used as one of the standards in the material selection with SSC and SCC resistance in H 2 S...

... ABSTRACT A previously developed modeling framework has been extended to predict the general and localized corrosion of various corrosion resistant alloys (CRAs), including alloys 2507, 2535, 28, 29, S13Cr, S15Cr, and S17Cr in complex aqueous systems relevant to oil and gas production...

... to localized corrosion under complex buried pipeline conditions. Electrode array-based corrosion probes were successfully deployed in selected locations across Victoria Australia. The probes performed as expected, providing a new point of view over the field conditions and the corrosion processes affecting...

... ABSTRACT Localized corrosion (pitting and crevice) is one of the main causes of damage of stainless steels in industrial applications. In order to study the corrosion behavior of stainless steel in the presence of chlorides, the Pedeferri’s diagram can be used. The diagram, originally...

..., which was pressurized to 1,000 psi with nitrogen. Two samples were tested for each neat product, one contained a UNS S31603 coupon and a second a UNS S31803 coupon. Test duration was one week. The analysis consisted of evaluation of the general and localized corrosion of the metal coupons and a visual...

ABSTRACT In the previous study by the same authors, a localized corrosion mechanism related to the presence of pyrite corrosion product was proposed by observing and replicating severe localized corrosion in sour environments. In the present study, in order to further validate this localized...
