Thermal Analysis of Repaired and Reinforced Steel Pipe with Composite Materials

Nowadays, composite materials are going to play a very significant role in repairing and reinforcing pipes because of easy installation and suitable cost. The applied reinforced composite layers shall be analyzed in different aspects. In addition to operating condition, one of the most important factors is temperature differences which may cause failure in steel pipe or in composite layers or even delaminating of composite layers as a consequence. In this study, the effect of thermal stresses caused by thermal expansion difference of steel and composite in reinforced piece has been considered. The theoretical analyses have been done for both longitudinal and redial cases to find proper composite layers and materials for a practical defected steel pipeline. Finite Element Analysis has been done by ANSYS software and the results compared with theoretical results. From the investigation, proper composite material and number of layers have been selected for above practical case.
