Technical Guidelines for Life Evaluation of Main Pressure-bearing Components of Power Plant Boilers1 ScopeThis document specifies the contents of the life assessment of the main pressure-bearing components of the utility boiler, establishes the life assessment procedures, and describes the life assessment procedures. method, which specifies the content of the life assessment report. This document is applicable to the life assessment of pressure-bearing components of boilers in use in power plants. This document does not apply to the pressure-bearing part of the boiler of the power station with excessive defects life assessment of parts.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
