摘要

The peculiarities of disassembly-free repair of steel grade 15KhlMlFL body of the control valve of the medium pressure cylinder of the turbine PT-200-130 of the heat power plant, in which a crack was formed after a long-term service, are given. The repair without disassembly of the valve is possible due to the use of technology of repair arc welding by pearlite electrodes with preheating and thermal recovery.
