The paper describes equivalent stress change of pipe with longitudinal volumetric form defect on pipe surface – approximated as half of ellipsoid. The optimal experiment design created to analyse that defect increase. For every size of modelled volumetric surface defect created different thickness of applied bandage. The equivalent stress for working pressure is numerically calculated using ANSYS software in pipe without defect, with defect and after composite repair with varying thickness of the bandage for different sizes of defect . All results are approximated and analysed.
