Structural Integrity of Welded Pipe Joints Made of Creep–Resistant Steel P91 with Multiple Defects: Experimental Characterization and Engineering Critical Assessment
This study provides a comprehensive analysis of the mechanical properties and structural integrity of butt-welded P91 creep-resistant steel pipe joints utilized in high-pressure piping systems. Two pipe specimens with an outer diameter of Ø48.3 mm and a wall thickness of 10.15 mm were welded using the GTAW process in t...
