Introduction. Longitudinally submerged arc welding (LSAW) pipes are widely used in the construction of oil and gas transportation pipelines, and most of such pipes are made from steel plates by the JCOE process (progressive forming process of J-shape, C-shape and O-shape, welding and mechanical expanding) and UOE process (progressive forming process of U-shape and O Effects of Simulation Parameters on Springback in Air In order to improve JCO forming quality, it is necessary to analysis deformation characteristic of air bending. So, air bending is analyzed using finite element method. Taking the air bending of

JCO is a widely used cold forming method for pipes which is named by the shape of the plate in the forming process, i.e. J-shape, C-shape and O-shape, and the forming process is an important parameter that determines the level of imperfections and residual stresses in a pipe, and residual tensile stress will accelerate corrosion failure of the pipe. Plastic deformation and fracture behavior of X65 pipeline Mar 15, 2018 · In this work, the plastic deformation and damage behavior of pipeline steel grade X65 were investigated experimentally and numerically by means of the Gurson-Tvergaard-Needleman (GTN) damage mechanics approach. The differences between observed microstructure characteristics of the center and skin region of examined pipe were taken into account. Research on deformation characteristics of JCOE forming in Taking the JCOE forming process of X80 steel 1 219 mm×22 mm×12 000 mm welding pipe for instance, the deformation characteristics of JCOE forming are analyzed, in which the geometry of the formed pipe, residual stress distributions and effects of process parameters on JCOE forming quality can be obtained. Thus, the presented results of this research provide an effective approach to improve welding pipe forming

The effect of spiral cold-bending manufacturing process on

Jul 01, 2019 · Moreover, an advantage of the spiral forming compared with other manufacturing process (UOE or JCOE processes) is that there is no final expansion stage. Due to the continuous nature of the forming process the circularity of the spiral pipe is very good.
