Analysis of failure of process pipeline, including a study of the properties, chemical composition and structure of the metal of welded joints, as well as the center of fracture and nature of crack propagation, made it possible to establish the most probable causes that led to its premature failure. It is assumed that such reasons are: a defect in a longitudinal weld; residual stresses in the pipe resulting from local heat treatment of the assembly circular weld; and probable longitudinal stresses arising from pipeline sagging between the supports. Ref. 9, 4 Tables, 7 Figures. [ABSTRACT FROM AUTHOR] |
