What is refractory inspection?

Refractory inspection is the process of evaluating the condition and integrity of refractory materials used to line high-temperature equipment such as furnaces, kilns, incinerators, and reactors. Inspectors assess for wear, cracks, erosion, and other types of damage that can compromise thermal efficiency or safety. Regular inspections help prevent costly failures and unplanned downtime by identifying maintenance needs early. The process may involve visual checks, non-destructive testing methods, and sometimes removing sections of refractory for closer examination.
