CEATI REPORT No. T203700-3715B for project 3715. The testing was performed and the report was prepared by Powertech Labs Inc. PRCI co-funded the CEATI project.
Research into the induction and conduction coupling response of a pipeline co-located with an electric power transmission line to assess the high voltage coupling response under fault conditions. Capacitive discharge tests were performed on primarily…
The objectives of the research were (1) to develop reliable measurement techniques to assess the level of cathodic protection (CP) in stray current areas, (2) to develop reliable CP criteria in the presence of stray currents, and (3) to identify and…
Evaluates commercially available interrupters to establish their limitations and performance characteristics. Six devices were tested over a 96 hour period in the laboratory, 48 hours in cold weather, and 48 hours in hot weather.
Explores new methods for assessing the threat of AC corrosion on buried pipelines. The results from this project will improve indirect inspection methods for assessing the impact of induced AC currents on pipeline corrosion rates and could be used…
This paper addresses the assessment of the corrosion risk of a pipeline due to alternating currents. The state of the art technique is the use of coupons, which simulate a coating fault and which allow to measure the ac-current density and also to…
This report refers to the activities performed in the frame of PRCI project on the refinement of the dynamic DC stray current corrosion criteria by applying an advanced DC corrosion prediction model.
This report refers to the activities performed in the frame of PRCI project on the evaluation of interference risk from high voltage power lines (HVDC) on buried pipelines. There exist different types of HVDC systems and configurations and only some…
Techniques employed by pipeline operators for locating static or dynamic stray current vary widely across the industry. PRCI has requested development of a process that operators can apply consistently to locate, validate, test and provide…
