METHOD FOR DETERMINING POTENTIALLY HAZARDOUS PIPELINE SECTIONS WITH BEYOND-DESIGN LEVEL OF STRESS-STRAIN STATE

摘要

FIELD: pipes.;SUBSTANCE: invention relates to operation of main pipelines, particularly to operation of potentially hazardous sections (PHS) with beyond-design level of stress-strain state (SSS).;EFFECT: invention comprises determining the PHS with beyond-design level of SSS, consisting in calculation assessment of bending stress according to in-line inspection (ILI), which measures radii of elastic bending of the pipeline during passaging a pig along the route.;1 cl, 1 dwg
