<jats:p> The study aims to explore the reasons for why the fracture defects in the forging of a long circular pipe part occurred. Besides, the tool design has been proposed to eliminate the fracture defects. The flow direction, the velocity, the effective stress, the effective strain, the damage value, and so on, can be observed by using the point tracking function in the commercial simulation software. Moreover, the forging stream line occurring in the work-piece formation based on the simulation software is compared with that in the real product in order to understand the reasons for the fracture. The tool designs are modified accordingly, and the simulation software is used to confirm the acceptance of tool designs. Finally, appropriate forging has been performed to as per product requirements. </jats:p>
