Abstract

Ovaj završni rad temelji se na analizi zahtjeva u proizvodnji tlačne opreme, s posebnim naglaskom na cjevovode i tlačne posude izrađene postupkom zavarivanja.
U teorijskom dijelu rada analizirani su relevantni pravilnici, regulative i norme koje se primjenjuju pri projektiranju, proizvodnji i kontroli opreme pod tlakom. Detaljno su opisani svi ključni koraci u konstruiranju tlačnih posuda i cjevovoda, uključujući odabir odgovarajućeg materijala i postupka zavarivanja. Također su navedena neka suvremena rješenja u proizvodnji i zaštiti tlačne opreme, poput primjene kompozitnih materijala. Dodatno, obrađen je pregled obveza proizvođača tlačne opreme, uključujući nužne resurse i postupke potrebne za osiguravanje visokih standarda sigurnosti i kvalitete u proizvodnji.
Eksperimentalni dio rada opisuje proces proizvodnje i pripadajuću dokumentaciju za čeličnu tlačnu posudu, na primjeru isparivača UNP-1800. Analizirana je odabrana tehnologija zavarivanja te ocijenjena sukladnost kvalifikacija postupaka zavarivanja i osoblja uključenog u proizvodnju. Priložena je dokumentacija koja dokazuje sljedivost proizvodnje i kvalitetu zavarenih spojeva. Na kraju je analizirano najkritičniji dio izrade u proizvodnom procesu te su predložene mjere za unapređenje proizvodnog procesa.

Abstract (english)

This final project focuses on the analysis of requirements in the manufacturing of pressure equipment, with a particular emphasis on pipelines and pressure vessels fabricated using welding processes.
The theoretical part of the project examines relevant regulations, standards, and norms applicable to the design, manufacturing, and inspection of pressure equipment. It provides a detailed overview of the key steps in designing pressure vessels and pipelines, including material selection and welding process determination. Additionally, modern solutions for pressure equipment manufacturing and protection, such as the application of composite materials, are discussed. Furthermore, an overview of the obligations of pressure equipment manufacturers is provided, including the essential resources and procedures required to maintain high standards of safety and quality in production.
The experimental part of the project describes the manufacturing process and corresponding documentation for a steel pressure vessel. The selected welding technology is analyzed, and the compliance of welding procedure qualifications and personnel involved in production is assessed. Supporting documentation is provided to verify production traceability and the quality of welded joints. Finally, critical areas within the production process are identified, and measures for process optimization are proposed.
