Boiler equipment remaining lifespan diagnosis

Evaluation using high-precision master curves! Introducing boiler equipment remaining life diagnosis.

Traditionally, equipment updates have been carried out based on recommendations from manufacturers' residual life assessments. However, with our high-precision residual life diagnostics, it is now possible to extend the timing of equipment updates and regular inspections. In the residual life assessment, we use a pre-established master curve to determine the life consumption rate from the values of damage parameters and evaluate the remaining life. Additionally, we manage and conduct residual life diagnostics for boiler equipment at Chugoku Electric Power's thermal power plants in a consolidated manner. 【Possible Areas for Residual Life Diagnosis】 ■ Equipment: Boiler equipment (2.25Cr-1Mo steel) ■ Diagnostic Areas - Large diameter pipes (main steam pipes, reheating steam pipes) - Pipe supports and pipe racks - Boiler tubes ■ Evaluation Methods - Void area ratio method - M parameter method - Grain deformation method (base material) *For more details, please refer to the PDF document or feel free to contact us.
