The methodology of a part lifetime calculation

Reducing mills in piece-reduction at the moment of capturing the pipe's front end and on the rear end exit are exposed to increased dynamic loads. However these processes at present time are not fully researched. The relevant problem is to decrease dynamic loads in the clamp engine, to increase reliability and durability of the clamp on the basis of the mill's production growth on the account of pauses decrease, rise of the production amount, and reducing in pipe costs. In the article the results of the study to define a part lifetime in the reducing mill stand have been presented. A part lifetime was calculated in month for more convenient comparison with the production data. The results have been hand over to JSC "PNTZ" for implantation. © 2020 IOP Publishing Ltd.

Exclusion of the pipe rear end defects in the process of the PRP 220 rolling using the FE modeling

A line for the production of hot-deformed pipes on a pipe-rolling plant 220 equipped with an automatic elongation mill is considered. In the maintenance the appearance of longitudinal end defects typical for thin-walled pipes was revealed. On the basis of a software package implemented with the use of FEM, a model of the deformation zone of a two-stage process of the lengthwise rolling of pipes on a short mandrel has been simulated. Analysis of the flow of the hollow bloom metal in this process makes it possible to establish the nature of the defect formation, as well as to calculate its influence on the power parameters of the process. The formation of a defect at the rear ends of the pipe is associated with the loss of stability of the hollow bloom section when the hollow bloom metal flows into the roll caliber outlets, which leads to an increase in the contact surface of the rolls with the workpiece and the mandrel with the workpiece, as well as to contact with the surfaces of the rolls that are not intended for direct interaction with heated metal. As a result, a technical solution has been proposed that allows restricting the loss of stability of the rear end of the pipe and eliminating a decrease in the loads on the working tool of the rolling stand, due to the degeneration of the rear end defects of the pipes. This solution is justified using FE modeling. © 2021 Author(s).European Space Agency, ESA, (15236/02/NL/SH)Deutsche Forschungsgemeinschaft, DFG, (GA 1142/11-1, LI 2827/2-1, RE 1261/23-2)Russian Science Foundation, RSF, (21-19-00279)The authors gratefully acknowledge financial support from DFG (LI 2827/2-1, RE 1261/23-2 and GA 1142/11-1)European Space Agency (ESA) within the project NEQUISOL under contract No. 15236/02/NL/SH, and Russian Science Foundation under project No. 21-19-00279

Theoretical Research on the Pipe Rolling Process in Order to Determine the Deformation of the Pipe Billet and the Load on the Rolling Tool

The technology of the shell case rolling into the rough pipe on an automatic mill of the pipe-rolling plant PRP 220 was considered. In case of the pipe rear end stability losing for a special thin-walled assortment of rolling products the theoretical research was carried out based on the FEM. As the result of the research the nature of such flaw as a "fin" on the end of the pipe was investigated, the evaluation of the loading on the automatic mill for the PRP 220 was obtained for different process parameters. © Published under licence by IOP Publishing Ltd

Intraoperative Intraluminal Endoscopy in the Surgical Treatment of Patients with Esophageal Diverticula of Various Localization

Aim. To improve the results of surgical treatment of patients with esophageal diverticulum of various localization using intraoperative intraluminal endoscopy. Materials and Methods: The Department of Surgery of the Esophagus and Stomach, the Petrovsky National Research Centre of Surgery, has accumulated a large experience in treating diverticulosis patients. Thus, during the 2010–2018 period, 74 patients with esophageal diverticula of various localization were operated. Out of them, 56 (75.7 %), 10 (13.5 %) and 8 (10.8 %) patients underwent surgical treatment with respect to faringo-esophageal, bifurcation and epiphrenic diverticula, respectively. The patients were divided into two groups: 31 people (41.9 %) in the main group underwent diverticulectomy with intraoperative intraluminal endoscopic assistance (IVEA), while 43 (58.1 %) people in the control group underwent diverticulectomy without IVEA. Intraoperatively, at the stage of discovering diverticulum, the endoscopist applied transillumination and air insufflation in the cavity of the diverticulum, followed by controlling the mobilization of diverticulum. At the resection stage, the completeness of the surgical removal was controlled, along with the absence of esophageal lumen narrowing after sewing the neck of the diverticulum using a linear stapler.Results. The average duration of the operation in patients with Zenker’s diverticula and those in the control group was 45.5 ± 8.8 min and 73.8 ± 12.7 min (p < 0.05), respectively. In patients with the diverticula of the middle and lower third of the esophagus, the average surgery duration was equal to 120.3 ± 11.2 min and 150.5 ± 17.3 (p <0.05) min in the main and control groups, respectively. Radiological examination 2–3 days after surgery revealed no complications in the main group. In the control group, 2 (4.7 %) patients showed a small leakage of the contrast agent outside the esophagus (stopped conservatively). Signs of mild dysphagia when taking solid foods were detected in 1 (2.4 %) patient of the control group. This condition was associated with excessive ingress of the esophageal wall into the apparatus suture, which led to a slight narrowing of its lumen. No patients with dysphagia in the postoperative period were recorded in the main group. Conclusion: The combination of surgical treatment of esophageal diverticula with IVEA allows the duration of surgery to be optimized, deformation of the esophageal lumen to be avoided, possible complications to be minimized, thereby improving the results of surgical treatment
