Information × Registration Number 0207U000028, 0104U006840 , R & D reports Title Research of modifications of service performances of metal of pipes from of controlled-rolling steel during long operation and development of methods of taking their into account for evaluation of availability index of product and residual safe life es of ріреlines popup.stage_title Head Rybakov Anatoly Aleksandrovich, Кандидат технічних наук Registration Date 03-01-2007 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 New data have been obtained about specifics of deformation ageing (DA) of material of pipes, made from controllable rolled steel, including those under conditions of service at arduous regions, and also about characteristics defining DA. Negative consequences are shown, which are observed in welds and soft regions of deformation localization in HAZ under the action of time, low temperature. It was established that hardness measurement can be used for defining DA at increased deformation. Rules of assessment of metal state and application of pipes of controllable rolled steel at arduous regions have been worked out. Product Description popup.authors popup.nrat_date 2020-04-02 Close
