Abstract
Izmjenjivači topline su uređaji u kojima se toplinska energija jednog fluida koji struji kroz izmjenjivač prenosi na drugi fluid koji struji kroz izmjenjivač bez njihovog međusobnog miješanja. Ovisno o izvedbi, često puta se provodi reparacija postojećih izmjenjivača. Primjer reparacije postojećeg izmjenjivača topline opisan je u ovom završnom radu. Za reparaciju je bilo potrebno izraditi novi distributor. Pri konstrukciji i izradi novog distributora korišteni su tehnički nacrti postojećeg distributora kojeg je bilo potrebno zamijeniti. Pri konstrukciji korišteni su različiti tipovi zavara, koji su naknadno ispitivani razornim i nerazornim metodama ispitivanja. U ovom završnom radu dan je opis izmjenjivača topline i njihovih elemenata, kao i opis uobičajenih metoda ispitivanja bez razaranja. Promatrana je konstrukcija jednog distributora izmjenjivača topline i praćena su NDT ispitivanja kontrole kvalitete zavarenih spojeva. Kako se radi o složenoj konstrukciji bilo je potrebno provesti više metoda ispitivanja. Zaključak kontrole kvalitete je kako su svi zavareni spojevi zadovoljili normom propisane vrijednosti, te je distributor bio spreman za ugradnju na postojeći izmjenjivač topline.
Abstract (english)
Heat exchangers are instruments in which thermal energy of one fluid, which flows through exchanger, is transferred to second one that flows through exchanger, without mixing up two of them. The existing exchangers often need reparation, depending on their performance. The example of reparation of the one heat exchanger is described in this paper. For reparation, it was necessary to build a new distributor. In the process of construction and making of new distributor, technical designs of existing one that needed to be replaced were used. In the process of construction, different types of welds were used, which were later tested with destructive and non-destructive methods. In this paper, a description of heat exchangers and their elements are given, as well as the description of usual non-destructive testing methods. The construction of new heat exchanger distributor was observed and afterward the NDT quality control test of welded compounds were monitored. As it was a complex structure, it was necessary to carry out several testing methods. The conclusion of quality control is that all welded joints meet the all requirement prescribed by used standards, and the distributor is ready for installation on the existing heat exchanger.
