ECA technologies are not very well known in the oil and gas industry and are still undeservedly suffering from the bad reputation of traditional eddy current testing from twenty years ago. Eddy current techniques are often humorously compared to "black magic" in the sense that the results are difficult to understand, the probes are complicated to use, and only eddy current gurus can use it efficiently. However, ECA has evolved significantly over the past 15 years and is now much easier and more intuitive to use.

Insulation Driven Intergranular Stress Corrosion Cracking of Carbon Steel

Product Number: 51324-20914-SG

Author: Matt Krantz; Yuan Li

Publication Date: 2024

Over the past decade, an increasing number of intergranular stress corrosion cracking (IGSCC) incidents have been observed on carbon steel assets operating in Alberta, Canada. At the time of publication, over 128 distinct cracks have been identified on 26 assets spanning at least 5 operators. All incidents have occurred on uncoated carbon steel operating between 70 °C and 190 °C and exposed to wet mineral wool insulation. Both piping and pressure vessels have been affected. Cracking has been isolated to assets with mineral wool insulation produced after 2003; however, a specific change to mineral wool composition in this timeframe has not been identified. The purpose of this paper is to provide a summary of incidents and investigations that have been reported to date and to update the environmental conditions (window of susceptibility) where insulation driven intergranular stress corrosion cracking has been observed. By drawing attention to this issue, it is the authors’ objective to increase awareness and determine if similar cracking incidents are occurring in other geographical regions.
