On Repair of Welded Joints of Heat-Resistant T91/P91 Chromium Steels During Use

Resumo

The basic problems that arise in the course of repairing the welded joints of high-temperature elements of heat-recovery boilers, manifolds, and steam pipelines of steam-gas power plants produced from heat-resistant T91/P91 chromium steels while in use are set forth. A review and analysis of repair technologies used abroad is presented.
