Деформаційний чинник у діагностуванні пароперегрівників парових котлів зі сталі 12Х1МФ

Abstract

The influence of deformation factor on serviceability of reheaters made from 12CrMoV steel is found. The changes of mechanical properties and microstructure of tubes from different sites of the creep remaining deformation are investigated. The estimation procedure concerning durability of the steam boilers reheaters of termal power plants on the basis of determination of exploitation equivalent temperature, degradation of microstructure and mechanical properties are presented.
