| Popis: | We analyze the causes of violation of the integrity of the body of gas-pressure regulator between the high-pressure and low-pressure compartments after 10 yr of operation, which caused the uncontrolled flows of gases between these compartments. The role of corrosion processes in the in-service degradation of the body of regulator is demonstrated. We study the structural features of 35L cast steel and analyze the causes of changes in its characteristics of plasticity and brittle-fracture resistance. |
