The influence of defects on strength characteristics of heat-exchanger tubes of steam generators PGV-1000

  • Published:
Strength of Materials Aims and scope

The test data for ring specimens from heat exchanger tubes without defects are compared to those for specimens with various types of defects. A relation between strength characteristics of the specimens and the nature and depth of defects has been clarified.
