NACE 10A392-2019 PDF Download

The NACE 10A392-2019 standard addresses the issue of external corrosion control on thermally insulated underground metallic surfaces. The standard highlights the current trend of using barrier coatings or adhesives prior to the application of thermal insulation as an effective method for preventing corrosion on metallic surfaces. It also emphasizes that the effectiveness of cathodic protection (CP) on bare or inadequately coated metallic surfaces under thermal insulation is generally limited.

This standard serves as an information guide, providing guidance and considerations for implementing effective corrosion control measures on thermally insulated underground metallic structures. It aims to inform and educate stakeholders, including engineers, corrosion experts, and maintenance personnel, about the importance of proper corrosion control techniques and the limitations of cathodic protection in specific conditions.
