Inspection, Repair & Maintenance Programs for Chimneys & Stacks
Chimneys and stacks are vital components of power production and industrial facilities. Their unique operating conditions subject them to a number of different factors that can be detrimental to their integrity including exhaust fumes and gases, fuel ashes, condensation, rain, thermal variations, UV exposure, lightning, atmospheric CO², wind and ground stability. These factors can lead to deterioration of both external and internal components.
Industrial Chimney Inspection
STRUCTURAL, a licensee of STRUCTURAL TECHNOLOGIES’ engineered products and services, offers several levels of chimney and stack condition assessment services based on the specific needs of the owner and the project. The objective of a comprehensive condition assessment is to identify the root cause of problems and the level of damage.
