Batch Pipe Forming Method Using Burring And Ironing of Diameter Steel Pipe by Fem Analysis

Abstract
Abstract - This paper describes Batch Pipe Forming Method Using Burring and Ironing of Large Diameter Steel Pipe. Branch pipes are one of the components of the piping system in a factory that serves as a flow path for gases and fluids. The bifurcated tube is formed by burring as a typical molding technique. The burring process is to form a branch pipe by raising the peripheral portion of the prepared hole formed in the mother pipe. There is a problem that the cutting of the edge is required in the post process. Therefore, a branch pipe batch forming method has been developed in which burring processing that does not require a cutting step in the subsequent step is combined with ironing processing using FEM analysis. The purpose of this study is to establish a batch forming method for branch pipes using the burring and ironing processes. Comparison of the analytical results with the experimental results suggests that a batch forming method for branch pipes can be performed using the burring and ironing processes.
