“…Via comparing the exerted force in the simulation with the average of 53.199 kN and the experimental results with an average of 48 kN and comparing the force fluctuations during the process, the accuracy of the FEM simulation results can be confirmed with the use of experimental results at the first 5 s of the process. 8 After mathematical modelling and carrying out simulation via FEM software, the extracted results are shown from all four assumed specimens within the process. In Supplementary table 2, the comparison has been illustrated between the geometrical parameters of the manufactured tube in all assumed types of RTP process.…”

The rotary tube piercing (RTP) is the first process of making the seamless tube after producing the desired alloy ingot. There are several approaches to manufacture a seamless tube, but one of the most common types is RTP. This approach covers a wide range of processes that are categorized according to the number and shape of the rollers. On the other hand, each of these types has designed guides in the output and input of the piercing process. In this paper, a new design of the input guide for four types of rollers have been examined and simulated. Thus, four specimens including Diescher and Conical rollers were considered, with the different number of rollers. Results including torque, total force, mandrel wear, temperature distribution, and strain were extracted using FEM simulation. In order to the validation of simulation, the total force and oscillations of applied force within the process have been compared with the experimental results. The results obtained through this simulation, are more in line with the empirical results obtained from previous research. As well as, the FEM simulation confirmed the performance accuracy of the output and input guides of the RTP process. On the other hand, the results indicate that the three-roller Diescher type with 17° feed angle, has the most suitable arrangement for production of seamless tube.

“…This point can express the condition of the mandrel is more critical than other components of the piercing system. Mao et al 7,8 developed the rolling process through numerical theoretical and experimental methods. The upper bound solution has been implemented as the theoretical section to calculate the load force was calculated.…”

“…It was found that the increased isotropy of the deformed and annealed aluminium sheet is a product of the texture heterogeneity and reduced volume fractions of the separate texture components. Mao et al [8] proposed tandem skew rolling (TSR) for the production of seamless tubes. In order to study the deformation characteristics and mechanism on tubes obtained by the TSR process, a numerical simulation of the process was analysed using Deform-3D software.…”

The wall thickness eccentricity is one of the most important weaknesses that appears in seamless tubes production, since this imperfection is subsequently transferred downstream through the manufacturing stages until the final product. For this reason, in this article a finite element model of the rotary tube piercing (RTP) process is developed aimed at analysing the wall thickness eccentricity imperfection. Experimental data extracted from the industrial process is used for the validation of the model, including operational process variables like power consumption and process velocity, and deformation variables as elongation and longitudinal torsion, originated by axial and shear strain respectively. The cause of longitudinal torsion is also analysed. The two most important conclusions derived from this study are: (I) the longitudinal torsion of the tube is a crucial parameter for the correct model validation, and (II) the combined effect between the uneven temperature distribution of the billet and the plug bending deformation is identified as the major cause of the wall thickness eccentricity flaw.
