Corrosion Growth Rate Analysis

Home - What we do - Activities - ILI qualification - Corrosion Growth Rate Analysis1

Corrosion of pipelines can occurs in many forms such as selective seam corrosion, uniform corrosion, or internal or external pitting to name a few.  The susceptibility to corrosion is influenced by an interaction of many factors including coating type, coating failure modes, cathodic protection (CP) effectiveness, sources of CP interference, operating temperatures, metallurgical conditions, and pipe interior environment.

In-line Inspections (ILI) are commonly implemented for the continued integrity management of pipelines, particularly in response to the ongoing threat of corrosion. The corrosion growth rate (CGR) plays an essential role in the optimization of re-inspection intervals.

Our method of obtaining the CGR uses successive ILI runs and performs a feature to feature comparison.

Successive ILI data can be correlated to identify areas of feature growth. Using the Kiefner CorroSure software, data can be inputted from two ILI runs from the same or different vendors, or  individual pit data, or interacted features. Sample data is selected at locations with evidence of active corrosion, determined by plotting the frequency of corrosion over the length of the pipe.

With over 20 years of experience, Kiefner has the expertise to support your In-line Inspection qualification needs.
