 Abstract
In the paper is presented a method for computing the safety geometry of expansion loops of the steam collectors used in petrochemical plants. The safety geometry of the expansion loops are obtained considering only the thermal expansion effect that is the most important one for the steam pipes. We illustrate our approach with a calculus example that includes three steam collectors (3’, 4”, and 6”).

 Rezumat
În lucrare se prezintă o metodă pentru calculul dimensiunilor geometrice sigure ale unui colector de abur utilizat în rafinării. Geometria sigură a lirelor de dilatare este obținută considerând numai efectul temperaturii exterioare, care este și cel mai important. Rezultatele obținute sunt analizate pe trei colectoare (3”, 4”, și 6”).
