The process of destructive and non-destructive testing of the manufacture of high frequency induction welded steel tubes has always give better results at the Labiod-tèbessa Algeria tube construction plant such as tensile testing, folding, flaring and also the flattening tests whose limits of use were given by the experimental methods which have known deficiencies in measures in particular of the parameter of the height H which is given by the equation and that this difficulty is noted between the calculated and measured height levels. For these reasons it is necessary to find a numerical model of simulation which obviously replaces the experimental process to give reliable results with cheaper conditions in terms of cost and time which has been respected which allowed us to collect data. results and compare the different heights calculated and measure and often confirm the experimental tests.
