Since our founding on November 23rd 1950, employees from all parts of the organisation have written and published in excess of 150 technical papers on corrosion prevention topics.
Many of our technical papers are available only in typewriter printed form, and we are currently in the process of typing and uploading those abstracts to this site. If you do not find the paper or the author that you are looking for, please check back in a week or two.
Recent close-interval potential surveys have raised concerns about the accuracy of potential measurements on some older pipelines. Two significant sources of error were identified: metallic IR-drops and equalization currents. These resulted in measured on and off potentials which differed by hundreds of millivolts from the […]
This paper covers various methods for dealing with sources of errors affecting the accuracy of the Direct Current Voltage Gradient (DCVG) coating defect identification and sizing tool. Topics reviewed in detail include: eliminating the influence of local soil resistivity and varying pipe depth on the […]
The quality of the indirect inspection data is a critical factor in conducting a successful ECDA. It is therefore essential to increase the accuracy of the field data collection, to improve the data processing and to effectively present the results. This paper describes several challenges […]
An AC interference study was conducted in 2015 following the installation of a new 240 kV powerline in a remote area of Alberta, Canada. The calculations indicated severe risk of AC corrosion for the paralleling pipelines and safety hazards for pipeline personnel, especially under fault […]
In recent years, effective techniques have been developed for conducting integrity assessments along cross-country pipelines. In order to provide similar confidence in facility integrity, it was proposed to apply a modified external corrosion direct assessment process to a small station. Until now, congested facility environments […]
Quelques avancées récentes dans la protection anodique des clarificateurs de liqueur blanche et verte et des réservoirs de stockage
La protection anodique (PA) est une technique performante pour réduire la corrosion des réservoirs de liqueur blanche et verte. Il est question des améliorations récentes. L’utilisation de sources de courant distribué (SCD) a entraîné la diminution de : 1) la participation du personnel des usines de […]
The analysis of indirect inspection data is a critical factor in conducting a successful ECDA process. This paper covers two lessons learned recently when dealing with bonded pipelines along common rights-of-way and also with equalization currents. The “old” challenge of differentiating between “threat” related versus […]
L’analyse des données d’inspection indirecte est un facteur essentiel dans la conduite d’un processus ECDA réussi. Cet article couvre deux leçons récemment apprises de l’utilisation de pipelines liés le long de droits de passages communs et des courants d’égalisation. Il sera aussi question de l’« […]
