Parametric Study of Large Diameter Wye Fittings Using Three-Dimensional Nonlinear Finite Element Analysis
Publication: Pipelines 2023
ABSTRACT
This article presents an in-depth stress analysis of a large diameter wye fitting using finite element analysis (FEA). The analysis aims to investigate the effect of different parameters on deflection and stress distribution at critical points. The paper presents the nominal FEA settings needed to achieve most reasonable results. Additionally, the effects of different boundary conditions of the FEA as well as minimum required fitting length for handling are investigated. Moreover, limitations of the wye fitting stresses are examined against the ASCE MOP 79 Steel Penstocks, and the effects of wye design parameters such as pipe diameter-to-thickness ratio (D/t) and crotch plate length-to-thickness ratio (Dw/t) are investigated in an attempt to reduce the cost and ease of installation of wye fitting with crotch plates. Finally, wye fitting with pressure diameter value (PDV) values of 6,000−10,000 is investigated to evaluate their performance according to the ASCE MOP 79.
