FLARE TEST ON WELDED STEEL TUBES; 2D SIMULATION

Abstract

This work address the simulation of the flare test as it performed on tubes welded by HF (high frequency) induction. Usually, at ENTTPP (National company of pipe mill and processing of flat products) where the test is carried out, the final products (tube) undergo a series of CD (destructive testing) in order to examine the efficiency of welding. In our context, the focus is on the flare test as one of these CD tests and by exerting efforts (pressure) on a predefined length sections from the pipe (of S235JR steel type in our case) and due to its share parameters namely mechanical (fracture resistance) and geometrical (thickness tube, outside diameter), the variation of this efforts is recorded, and the results is well investigated in order to be simulated on computer using finite element method based programing language (Castem version 2001)
