Abstract
U teorijskom dijelu objašnjeno je zašto je baš vodik aktualan u energetskoj tranziciji i zašto se kod distribucije medija javljaju značajni problemi na područja zona zavarenih spojeva. Objašnjeni su njegovi mehanizmi djelovanja za zonu zavarenog spoja te kritične mikrostrukture. Prikazati su čelici za izgradnju cjevovoda prema zahtjevima norme API 5L s naglaskom na čelik X70 koji se najviše koristi te je dan pregled automatskih postupaka zavarivanja. U eksperimentalnom dijelu na temelju mehaničkim karakteristika zavarenog spoja načinjenog postupkom 135 automatskim zavarivanjem na cijevi D406,4x25 mm ocjenjena je prikladnost tehnologije za transport vodika. Posebno su analizirane tvrdoća i makrostruktura spoja te je na kraju dana preporuka o prilagodbi postojeće tehnologije za tzv. „hydrogen ready“ cjevovodne sustave.
Abstract (english)
In the theoretical part, the relevance of hydrogen in the energy transition is explained, along with significant challenges in the distribution of the media in the areas of welded joints. The operating mechanisms for the welded joint zone and critical microstructures are elucidated. Steels for pipeline construction according to API 5L standards are presented, with a focus on X70 steel which is most commonly used, along with an overview of automatic welding procedures. In the experimental section, based on the mechanical characteristics of a welded joint made by the automatic welding process 135 on a pipe of D406.4x25 mm, the suitability of the technology for hydrogen transport is evaluated. The joint's hardness and macrostructure are specifically analyzed, and recommendations for adapting the existing technology for "hydrogen-ready" pipeline systems are provided.
