“Prykarpattransgaz” for creation of a database of characteristics of operated steels

and for determination the residual lifetime of pipeline sections and substantiation

of their reconstruction. The method for diagnostics of the condition of steels based

on their resistance to fatigue failure was implemented at LLC “Porttehekspert”

(Odesa) to assess the operational degradation of steels of port cranes that are

subjected to combined action of cyclic loading with high asymmetry and marine

atmosphere.

Keywords: pipeline steel, weld joint, electrochemical properties, cavitation,

stress corrosion cracking, corrosion fatigue, hydrogenation, operation.
