The flower pattern and rolls design for ERW pipes with the different specification in the flexible roll forming process

To produce electrical resistance welding (ERW) pipes with the different specification efficiently and economically, flexible roll forming technology is urgently required. Based on the elastic plasticity deformation theory, combined with the basic parameters of typical roll forming units, the 3D finite element analysis (FEA)models of ERW pipes with seven kinds of sizes were built and the numerical simulations were conducted with the professional...
