Criteria for the evaluation of the technical state of the long-lived metal of HPP equipment based on acoustic structuroscopy
Source abstract
Abstract
The criteria for the maintenance evaluation of long-lived metal of the equipment of heat power plants during the acoustic structuroscopy of weld joints of vapor pipelines and boiler drums are described. The data on the change of the structural state of metal during long-term operation of heat-resistant steels are given. The dependences of the criteria versus the values of local fields of internal stresses of a crystal lattice are given. The relationship between the integrated criterion and the durability of heat-resistant steels is presented.
