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 […]
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 […]
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 […]
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 […]
When installing pipelines in rocky areas, additional mechanical safeguards may be necessary to protect the coating. These safeguards may take the form of intermittent supports which elevate the pipeline off the trench bottom. As such supports are non-metallic and are installed directly against the pipeline […]
The Maritimes and Northeast Pipeline on the east coast of North America is constructed through an area where large geomagnetic disturbances can be expected. Because of this it was decided to include consideration of telluric current effects in the design of the cathodic protection (CP) […]
This paper reports another successful application in industry of the rapidly expanding science of anodic protection. In the seven years during which this application has been under development, anodic protection has emerged from the laboratory into industry, where it is now being successfully used in […]
