Description
Summary:The first paper of the present series appearing in Experimental Techniques highlighted the increased need and opportunity for applying experimental techniques in the field of pipeline integrity.1 The series' second paper2 presented the analysis of strain data acquired by using postyield strain gages bonded inside the metal loss areas of different pipe specimens loaded with internal pressure. At those points, much resistance is offered to the longitudinal strains by the thick walls parallel to the metal loss strip, as can be noticed by the small longitudinal strain values.2 A table was also introduced, summarizing tests that were performed in order to validate calculation procedures for predicting burst pressures of defective pipes, and procedures or products for repairing and reinforcing such pipes.
