AB  - Topic of this work is the integrity assessment of the pipeline section from hydropower plant Pirot. Crack-like defect size, maximum depth, is determined based on non-destructive evaluation - the largest crack depth is taken as the initial value for load carrying capacity estimation. Also, the crack dimensions (both length and depth) are varied. Limit pressure values are determined from 3D and 2D models of pipes with axial cracks on external surface. The influence of tensile loading on the load carrying capacity of the pipes with circumferential cracks is also examined. Integrity of pipes with both types of defects (axial and circumferential) is assessed through application of FAD diagrams.

AB  - The selection of steel, the dimensions and methods of seam welded steel tubes fabrication are closely connected to the function of tube as a whole structure in specific working conditions, for a calculated service life. The quality of welded joints in the fabrication process of seam welded tubes is defined by properties the tubes must possess in order to satisfy defined requirements, and can be achieved by choosing appropriate procedures and welding parameters, by following control programmes in all fabricating operations, and through mechanical and technology stress and strain tests of base metal and seam welded joints. The paper presents the results of the mechanical properties of spiral welded pipes, the two production processes with different welding parameters. Tubes designed for oil and gas pipelines are made by welding the powder (EPP) steel increased strength of API X60.
AB  - Izbor čelika, dimenzija i načina proizvodnje zavarenih cevi je deo procesa konstruisanja, jer je u uskoj vezi sa funkcijom cevi kao konstrukcijske celine u određenim uslovima eksploatacije za predviđeni vek trajanja. Kvalitet zavarenih spojeva u procesu proizvodnje cevi definiše se karakteristikama koje one moraju posedovati da bi zadovoljile određene zahteve, što se postiže izborom odgovarajućih postupaka i parametara zavarivanja, sprovođenjem programa kontrole svih tehnoloških operacija u njihovoj izradi i mehaničkim i tehnološkim ispitivanjima otpornosti i deformacije osnovnog materijala i zavarenih spojeva cevi. U radu su prikazani rezultati ispitivanja mehaničkih osobina spiralno zavarenih cevi, za dva proizvodna procesa sa različitim parametrima zavarivanja. Cevi namenjene za naftovode i gasovode su izrađene zavarivanjem pod praškom (EPP) od čelika povećane čvrstoće API X60.
