Modeling and Evaluating the Stress of Two Mechanical Structures in Piping Industry -The Ring Flange and the new Quadra-Sector Flange-

Nour-Eddine M’haouache, Hanaa Hachimi, Safae Assif, Moulay Taib Belghiti


This article deals with the economic aspect and the mechanical reliability of two variants of a structure. One variant is known and marketed (Ring Flange); the other is innovative and marketed without warranty specifications (Quadra-Sector Flange). The raw material benefit is the compromise between the two variants, and the warranty expected by the customers remains the concern. The manufacture of the two structures is carried out in two operating modes and based on the same raw material; they also both work in the same conditions. The rationale behind this study is reassuring the customers, showing them both patterns by means of a thorough structural stress study based on analyzing our input data (external effects) and comparing the results of the two patterns.
