Curenje posude za skladištenje CO2 od austenitnog čelika / Leakage of an austenitic steel CO2 storage tank
(Institut za ispitivanje materijala, Beograd, 2012)
Posle pojave vodenih kapi na spoljašnjem zidu otvora za reviziju posude za skladištenje ugljen dioksida, detaljnom inspekcijom je otkrivena mreža prslina na prirubnici revizionog otvora, blizu zavarenog spoja između ...
Strategija održavanja zasnovana na riziku - primenljivost na cevovod / Applicability of risk-based maintenance strategy to a penstock
(Institut za ispitivanje materijala, Beograd, 2012)
Rizik od krtog loma cevovoda reverzibilne turbine je ocenjen u ranoj fazi projektovanja. Da bi se smanjili troškovi izgradnje cevovoda prihvaćen je jedan tunel. Zbog toga je za najopterećeniji segment cevovoda izabran HSLA ...
Effect of temperature and exploitation time on tensile properties and plain strain fracture toughness, K-Ic, in a welded joint
(Elsevier Science Bv, Amsterdam, 2018)
Effect of temperature and exploitation time on resistance to brittle fracture of welded joint constituents of new and 40 years exploited low-alloyed Cr-Mo steel A-387 Gr. B has been analysed. The plane strain fracture ...
Integrity and Life Assessment Procedure for a Reactor
(Elsevier Science Bv, Amsterdam, 2019)
Integrity and life assessment of structural elements or structures subjected to variable loads is necessary in order to define the control interval and removal of damages that occurred during exploitation. Integrity and ...
Risk based analysis of temperature and time effects on brittle fracture of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
Risk based analysis of temperature and time effects on fracture toughness values is applied to different regions of a welded joint made of low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. ...
Relation between impact and fracture toughness of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
The influence of temperature on impact and fracture toughness values in different regions of a welded joint is analysed for low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Standard Charpy ...
Numerical prediction of ductile fracture resistance of welded joint zones
(Elsevier Science Bv, Amsterdam, 2016)
This study deals with the numerical prediction of ductile fracture initiation and development in welded joints of a high strength low alloyed steel. Having in mind the material heterogeneity in the joint zone, a combined ...
Crack growth resistance of weldment constituents
(Elsevier Science Bv, Amsterdam, 2018)
The ovennatching can affect the occurrence of cold cracks after welding in high-strength low-alloyed steels of 770 MPa yield strength class. The welding consumable has been designed in a way to produce WM with slightly ...
Analysis of SA 387 Gr. 91 welded joints crack resistance under static and impact load
(Elsevier Science Bv, Amsterdam, 2021)
This paper presents the results of experimental testing of crack resistance of specimens taken from a welded plate made of steel SA-387 Gr. 91, while taking into account different filler materials and welding procedures ...
Influence of temperature and exploitation time on hardness and micro-structure of a welded joint in a reactor mantle
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents the analysis of the influence of temperature and exploitation time on the cross-sectional hardness and microstructure changes of characteristic zones of a welded joint made of low-alloyed Cr-Mo steel ...
