- Title
PECULIARITIES OF DEGRADATION OF METAL OF WELDED JOINTS OF STEAM PIPELINES OF HEAT POWER PLANTS.
- Authors
DMITRIK, V. V.; BARTASH, S. N.
- Abstract
The peculiarities of degradation of structure and damageability of metal of welded joints of the steam pipelines of heat power plants of long-term operation period (more than 250,000 h) under the conditions of creep and low-cyclic fatigue are given. It is shown that welded joints of steels 15Kh1M1F and 12Kh1MF are damaged mostly along the areas of fusion, overheating and partial recrystallization of metal in the near-weld zone and also in the places of joining pipe elements of different thicknesses. 13 Ref., 1 Table.
