Information × Registration Number 0212U002878, 0111U008629 , R & D reports Title Tool design development for the plate flanging press at pipe electric welding installation "1020B" for the production of 508-1067 mm diameter, 7-32 mm wall thickness single-seam pipes of up to K60 strength group steel at VMZ JSC pipe electric welding shop. popup.stage_title Head Zaplatkin Urij Ananijvich, Registration Date 24-02-2012 Organization State Scientific Research Tube Institute popup.description2 Analysis of the current technology for press crimping of plate edges in line of 1020B pipe welding installation by the results of manufacture of 508-1067 mm diameter, up to 32 mm wall thickness pipes of K65 strength group steel has been made. It was established that the designed product range was expanded by 9% in the entire diameter range, pipe wall thickness was decreased by 10-22% and yield strength of the used steels was increased by 16.6%. Based on the analysis of the technology and the used tools of P9047edge crimping presses, it was found that after crimping of plate edges for making thick-walled pipes, overformed edge sections are observed resulting in higher deviations from a theoretical circle in the zone of the finished pipe welds. Measures were worked out for elimination of the revealed imperfections and press crimping tool design was improved for the operating 1020B pipe welding installation in accordance with the Technological Direction 22-TR.TS-40-2011 up to K65 strength class and X80 strength group. Punch and die dimensions were determined in accordance with the design position of the tool shoes. The calculation of energy-power parameters of the process with the use of the developed tooling has shown that the forces acting during crimping of edges of the plates produced from X80 strength group steels do not exceed the press name table data.
