Abstract

This chapter is dedicated to the analysis of the efficiency of a given repair system using composite material wraps intended for damaged sections with volumetric surface defects of transmission pipelines (for petroleum, liquid petroleum products or natural gas). The analysis refers to the composite repair system investigated in Chapter “ Inner Pressure Testing of Full-Scale Pipe Samples” and it has used the experimental data presented in Chapter “ Inner Pressure Testing of Full-Scale Pipe Samples”. The tests performed were defined based on the considerations in Chapter “ Development of an Experimental Programme for Industrial Approbation”. The efficiency assessment has been made, in the first place, considering the change of volume and the yield pressure, then taking into account the changes observed in the samples perimeter. The effect of the composite wrap on the deformations recorded for each defect and the loading diagrams have also been investigated. Finally, the efficiency has been assessed using a numerical finite-element model.
