Next Step To Advanced Data Analysis With Pulsed Eddy Currents

Product Number: 51322-17568-SG

Author: Donald Picard, Olivier Bellavance, Gabriel Cyr, Andréanne Potvin

Publication Date: 2022

$20.00

Pulsed Eddy Current (PEC) technology is a widely accepted inspection method now covered by several industry standards such as ISO⁽¹⁾ 20669, API⁽²⁾ RP 583, and the new ASME⁽³⁾ Section V (BPVC for Boiler and Pressure Vessel Code), article 21. PEC is a versatile inspection technology which provides an average remaining wall thickness through insulation and coatings. The technique can also be used to safely assess the minimum remaining ligament under corrosion scabs or blisters without surface preparation. PEC is resilient to liftoff variations and provides volumetric measurements of remaining material. It is capable of both detecting and assessing general corrosion on the outer surface of the pipes such as scabs and blisters, and detecting erosion or Flow Accelerated Corrosion (FAC) on the inner surface.

Modern-day risk-based inspection (RBI) platforms are designed to evaluate the safety and/or financial risk of assets using industry-recommended RBI methodologies (e.g., API 581). There are cases where the RBI methodology does not represent the true risk profile of the asset, despite implementing the best possible inspection programs and careful input of inspection data. One of the main pitfalls present is the inherent limitation in the risk calculation methodologies that makes no or little use of the inspection data. An example of such a situation is the CUI risk assessments that are subjected to uncertainties due to numerous scientific parameters that are partially addressed (or even unaddressed) in modern-day RBI approaches. This work addresses two case studies of external corrosion rates due to CUI for two pairs of test rigs made with small bore piping deployed with two different insulation designs, namely conventional design, and moisture egress design. The assemblies were tested using two different methods for CUI simulation and testing conditions. The first pair was tested per ASTM G189-07 under isothermal wet-dry conditions at 100 °C (212°F) for three days, while the second pair was submerged under water for two days followed by outdoor exposure for one year. The experimentally determined corrosion rates were compared to those calculated using API 581-compliant RBI software. The comparisons of resulting corrosion rates are complemented by an explanation of the deviations and pitfalls.

The range of factors affecting the susceptibility of equipment to corrosion under insulation (CUI)
are numerous. Some of these factors might be controlled through better design, more robust
installation procedures, and using better quality coatings. However, there are other risk factors such as operating temperature, material type, and environmental conditions that cannot be easily modified.

Corrosion under thermal insulations namely CUI (Corrosion under insulation) is among the key degradations posing integrity risks to the hydrocarbon processing, chemical, and petrochemical facilities. CUI is reportedly known as the reason behind 40-60% of failures in the piping for the oil refineries. Whereas the small-bore piping (i.e., NPS< 4”) is more prone to this damage mechanism where reportedly where up to 81% of failure result from CUI.
