20.500.12556/DKUM-58520 Načini spajanja cevi v slovenskih plinovodnih omrežjih s primerom zagotavljanja kvalitete varilskih del na plinovodu R23A Different techniques of joining Slovenian gas network pipelines with example of quality assurance of welding on pipeline R23A Diplomsko delo obravnava področje varjenja plinovodnih cevi in zagotavljanje kvalitete varilskih del. Varjenje je najpogostejši način spajanja cevi na plinovodih v nerazstavljivo celoto. S povečanjem potreb po energiji in s tem tudi po plinu, se prenosna in distribucijska plinovodna omrežja širijo tudi v Sloveniji. Zato je ob povečanem obsegu varilskih del, potrebno izbrati prave postopke in zagotoviti kvaliteto del. Opisani so postopki varjenja in spajanja plinovodnih cevi ter postopki zagotavljanja kvalitete varilskih del. Na praktičnem primeru prestavitve prenosnega plinovoda R23A je prikazan celoten postopek od zasnove, izbire materialov in postopkov, priprave, varjenja cevi, kontrole kvalitete zvarov, zaščite, dokumentacije pa do predaje objekta v uporabo. The thesis focuses on the field of welding gas pipelines, and quality assurance of welding works. Welding is the most common way of fusing pipes in gas pipelines into a conjoined entirety. Due to the increasing need for energy, and consequently gas, gas transmission and distribution networks are also expanding in Slovenia. Therefore it is important to choose the right procedures, and ensure the quality of the ever-growing work. Described are the welding procedures of gas pipelines, and the quality assurance procedures for the welding works. The procedure of designing, choosing materials and procedures, preparation, welding of the pipe, quality control of the welds, protection, documentation, and handover of the object for usage are shown on the practical example of the transmission gas pipeline R23A. zvar varjenje cevi plinovod kontrola zagotavljanje kvalitete weld pipeline welding gas pipeline inspection quality assurance true true false [Z.
