The influence of external bending moments on the lifetime of bends in hot reheat pipelines

Durability of bends in high-temperature steam lines under the conditions of long-term operation

“…Along with simplified analytical assessments of the stressed state of pipeline bends based on the theory of thin shells, a finite element solution of the problem in a 3D statement [2,3], which makes it possible to take into account a number of geometrical and force fac tors, has recently been increasingly more frequently used for analyzing the durability of bends.…”

“…This work, which is a further development of the approaches suggested in [2,3], is aimed at studying the 1 Despite the fact that many statements and conclusions contained in this article are subject to discussion, the material outlined in it may be of interest for specialists engaged in carrying out strength calculations and evaluating the lifetime of steam line bends.…”
