20.500.12556/DKUM-61251 Metoda za določitev degradacije vročevodnih cevi na osnovi meritev neravnin profila The method for determination of the district heating pipes degradation based on the profile roughness measurements V magistrskem delu je prikazana problematika korozijskih pojavov na vročevodnih sistemih, z njo povezanih dejavnikov in priporočil za obvladovanje tovrstnih tveganj ter posledično stroškov. Na podlagi izvedenih raziskav in analiz vzorcev korozijsko degradiranih cevi vročevodnega sistema se je razvila inženirska metoda za ocenjevanje korozijske degradacije vročevodnih cevi. Metoda temelji na inovativnem pristopu digitalizacije površine korozijsko degradiranih vročevodnih cevi z oblakom točk in kompleksni numerični analizi prereznih ravnin. V delu se je določila relevantna gostota prereznih ravnin na merjencu, ki je še zagotavljala dovolj natančno oceno stanja površine in tako dotrajanosti (stopnje degradacije) jeklene cevi. Predstavljene so tudi metode oz. procedure ocenjevanja vplivov korozijske degradacije na varnost in zanesljivost obratovanja distribucijskih sistemov. Master thesis presents the overview of corrosion phenomena on district heating systems and associated factors, as well as recommendations for hazard and cost management. Engineering method for the evaluation of corrosion degradation of district heating pipes has been developed based oh the research and sample analysis of corrosion degraded pipes of a district heating system. The method is based on an innovative approach of surface digitalization of corrosion degraded pipes with the point cloud and complex numeric analysis of cross-section planes. In this thesis a relevant density of pipe cross-section planes that still provides sufficiently precise estimate of the surface condition and therefore the wear (level of degradation) of a steel pipe has been determined. Methods/procedures for evaluation of the corrosion degradation influence on safety and operation reliability of the distribution systems has also been introduced.
