Corrosion resistance of welded pipe in oil wells / Otpornost na koroziju zavarenih cevi u naftnim bušotinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Steel pipes in oil and gas wells are continuously exposed to the process of corrosion-assisted elevated temperatures and pressures prevailing in the interior of the tube. Corrosion can lead to significant reduction of ...
Strength design calculation of a horizontal pressure vessel / Kontrolni proračun čvrstoće horizontalne posude pod pritiskom
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
Standards SRPS M.E2.250-262 for calculation of pres-sure vessels have been replaced by SRPS EN 13445-3. This means that calculations of new equipment and check calculations of equipment in service are subjected to ordinance ...
Effect of the pH of artificial saliva on ion release from commercially pure titanium / Uticaj pH vrednosti veštačke pljuvačke na otpuštanje jona iz komercijalno čistog titana
(Faculty of Technology, Novi Sad, 2013)
Due to their excellent characteristics, such as chemical inertness, mechanical resistance, low Young's modulus, high corrosion resistance, and outstanding biocompatibility, titanium and its alloys are the most used metallic ...
Influence of working conditions on strength calculation of pressure vessel of austenitic steel according to SRPS EN 13445 / Uticaj radnih uslova na proračun čvrstoće posude pod pritiskom od austenitnog čelika prema SRPS EN 13445
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
Upon the adoption of regulations for pressure equipment the series of standards SRPS EN 13445 began to apply. The paper illustrates strength calculation of a vertical cylindrical pressure vessel of austenitic steels according ...
Preparation of glass-ceramic in Li2O-Al2O3-GeO2-P2O5 system
(University of Novi Sad, 2013)
The results of preparation and structural characterization of glass-ceramics from the system Li2O-Al2O3-GeO2-P2O5 are shown in this paper. The crystallization behaviour of the selected glass was examined under non-isothermal ...
Characterization of oxide coatings formed by plasma electrolytic oxidation of aluminum in sodium tungstate / Karakterizacija oksidnih slojeva dobijenih plazma elektrolitičkom oksidacijom aluminijuma u natrijum volframatu
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
This paper presents our recent research on morphology and phase composition of oxide coatings formed by plasma electrolytic oxidation of aluminum in 0.1 M sodium tungstate at constant current density of 15 mA/cm2 and ...
Efficiencies of different methods for determination of organophosphate pesticide residues in fermented wheat substrate / Efikasnost različitih metoda za određivanje ostataka organofosfata u fermentisanim uzorcima žita
(Institute of Pesticides and Environmental Protection, 2013)
In the present work, the efficiencies of three different sample preparation methods for GC/ MS determination of pirimiphos-methyl and chlorpyrifos-methyl residues in wheat (Triticum spelta) samples fermented by Lactobacillus ...
Quality assurance of storage tanks after in-service crack repairs / Osiguranje kvaliteta rezervoara u eksploataciji posle popravke prslina
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
According to the Pressure Equipment Directive (PED 97/23/EC) a new produced storage tank can be accepted on the market only if the required quality is proved. In this way the structural integrity might be at the requested ...
Microstructural characterization of glass-epoxy composites subjected to tensile testing / Mikromehanička karakterizacija staklo-epoksi kompozita izloženog zateznom opterećenju
(Faculty of Technology, Novi Sad, 2013)
The main objective of the research presented in this paper was to carry out a statistical-mechanical analysis concerning the tensile test of glass-epoxy composite materials in order to calculate their relevant tension ...
Examination of wear resistance of polymer-basalt composites
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2013)
Olivine basalt, as a natural material, has excellent physical and mechanical properties such as hardness, compressive strength, wear resistance, color and gloss. On the other hand it is difficult for processing, because ...
