Abstract: Many pipeline defects may reduce the working security as leakage liquid or may be more serious as cause explosion accidents for gas pipeline. This study focus developing the multiple pipeline defect model by guided waves system. The guided wave system consists mainly of one or group of transducers that are placed on the structure to detect the existence of defect. All testing pipe model section sample parameters are the same to 1 m long, 60 mm diameter and the wall thickness is 4 mm. The solid model FEA, the shell-63 element is selected. The pipes structures are studied by ANSYS Version 17.1 for multi cracks pipes structure in different design versions. The simulation result for the defect degree of central angle is used to identify three cracks types and the size of defect and holes will carry out to simulate in the same way.
