Simulation and Mathematical Modeling on Bending of Pipe Subjected to Internal Pressure

Abstract:

This Paper Aims from the Simulation Tests to Highlight the Influence of the Diameter and Material Quality, Reflected by the Flow Limit of the Pipe and the Quality and Technological Parameters at the Bending under Pressure of the Pipes. from Literature, those Quality Parameters which Characterize a Correct Bending are: the Ovality of the Transversal Section, the Variation of the Wall Thickness or Eccentricity, the Lack of Whetstones, the Resistance in Function of the Bent Pipe. Pipe Material Characteristics Influence the Quality Parameters of the under Pressure Modeling Process, in the Sense that at the Materials with Small Flow Limit, Ovality or Variation of the Wall Thickness are Small. at Pipes under Pressure Modeling, Ovalities and Variation of the Wall Thickness are in Permissible Limits Valid Recommended for Domains without Special Precision Restrictions.
