Experience and problems of estimation the structure and mechanical properties degradation for pipeline steels

Abstract

The problem of estimation of the actual technical state of metallic constructions of the different setting
in industry becomes especially actual in the conditions of sharp requirement in extending of exploitation
of objects that worked the normative resource. With the increase of age of the pipeline systems the
new scientific and technical problems of estimation of degree of degradation of structure and physical
mechanical descriptions of material of pipelines and possibility appeared them further exploitation
