An Investigation of External Corrosion At Ambient Temperature On Thermally Insulated Pipes Under Ageing Conditions

Product Number: 51323-19350-SG

Publication Date: 2023

Corrosion under insulation (CUI) is among the key damage mechanisms in the hydrocarbon industry which mainly manifests localized corrosion on thermally insulated equipment, tanks, piping, and pipelines. CUI is a highly frequent degradation in the oil refining facilities where reportedly 40-60% of failures in the piping result from CUI. In addition, small bore piping (i.e., nominal pipe size, NPS < 4 inch. or 100 mm) are even more prone to CUI and reportedly up to 81% of failures in these piping caused by CUI.

CUI (Corrosion under insulation) is among the key damage mechanisms in the process and hydrocarbon industries which results in the localized corrosion (mainly) thereby reducing the service life of the assets (pipes, equipment, etc.) CUI is reportedly known as the reason behind 40-60% of failures in the facility piping whereas small bore piping (i.e., NPS< 4”) are even more sensitive to CUI failures, where up to 81% of reported failures in small-sized piping are known to be from CUI. Monetary spending to inspect and fix CUI-related failures cost 10% of overall maintenance budget in a typical medium-sized oil refinery. CUI risk is influenced by numerous operational and environmental factors which impedes its management in a typical AIM (Asset integrity management) program.

CUI (Corrosion under insulation) is among the key damage mechanisms affecting the integrity of equipment, piping, and pipelines in the hydrocarbon industry. CUI manifests (mostly) localized corrosion.  CUI is a highly frequent degradation in the oil refining facilities where reportedly 40-60% of failures in the piping result from CUI.

CUI (Corrosion under insulation) refers to localized corrosion under thermal insulations, which pose integrity risks to the hydrocarbon facilities. 1 CUI is reportedly a driver behind 40-60% of failures in the facility piping. Smaller-sized piping (i.e., diameter < 4”) are even more prone to CUI, whereas reportedly 81% of failures in small-sized piping are due to CUI. 2 CUI-related failures and associated efforts comprise 10% of a facility’s maintenance budget. Management of CUI risks has always been challenging as it involves maneuvering numerous governing factors. The key driving factor behind CUI is the aerated moisture that comes from soaked thermal insulations.

Publication Date: 2023
$20.00

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.
