dc.description.abstractAccording 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 level. However, it is not possible to apply all rules and standards for the quality during service and after performed repairs that are necessary to sustain the structural integrity of the storage tank. Storage tanks of steel are produced in general as cylindrical or spherical, and individual segments are joined by welding. Welded joints are prone to crack occurrence, and for that they are critical locations for safety and structural integrity. According to standard EN ISO 5817 cracks are not acceptable defects in welded structures, and detected cracks have to be removed. The applicability of quality assurance approach to repaired pressure equipment is analyzed and discussed in this paper. In the first case welded joints in spherical storage tanks produced of normalized high strength steel (460 MPa yield stress) microalloyed with vanadium are analyzed, considering repair and structural integrity assessment. In the second case, dissimilar welded joints of structural and stainless steel are examined.en
dc.description.abstractPrema Direktivi za opremu pod pritiskom (PED 97/23/ EC) novo proizvedeni rezervoari se mogu prihvatiti za tržište samo ako je zahtevani kvalitet i dokazan. Na taj način integritet konstrukcije može biti na zahtevanom nivou. Ipak nije moguće sprovesti sva pravila i standarde za kvalitet tokom eksploatacije i posle izvedenih popravki, potrebnih da se održi integritet konstrukcije rezervoara. Rezervoari od čelika se uglavnom proizvode kao cilindrični ili sferni, na kojima su pojedinačni segmenti spojeni zavarivanjem. Zavareni spojevi su skloni pojavi prslina, i zbog toga su oni kritična mesta za sigurnost i integritet konstrukcije. Prema standardu EN ISO 5817 prsline nisu dopuštene greške na zavarenim konstrukcijama, i otkrivene prsline treba da se eliminišu. Primenljivost pristupa osiguranja kvaliteta na popravljenu opremu pod pritiskom je u ovom radu analizirana i diskutovana. U prvom primeru su analizirani sferni rezervoari izrađeni od normalizovanog čelika visoke čvrstoće (napon tečenja 460 MPa) mikrolegiranog vanadijumom, razmatranjem popravke i ocene integriteta konstrukcije. U drugom primeru su ispitivani raznorodni zavareni spojevi konstrukcijskog i nerđajućeg čelika.sr
