A Simulation of the Post-Bending Process of the Pipe Billets for Welded Pipe Manufacturing

摘要

The paper presents a result of the simulation of the post-bending process of the pipe billet, using the MSC.Marc software package. It was shown that the use of a standard method for carrying out post-bending process leads to the formation of various defects, such as a variable gap between the edges along the pipe axis, vertical waves and bends at the edges, as well as a decrease in a sheet thickness on the edges.
