Assessing the remaining life of bends of live steam conduits from steel 15Kh1M1F

  • Published:
Power Technology and Engineering Aims and scope

Abstract

It is shown that the remaining life of bends of steam conduits from steel 15Kh1M1F should be evaluated on the basis of results of estimation of microdamage of the metal performed on a representative sample with allowance for the operating factors.
