This paper presents vibration analysis and mathematical model using Euler-Bernoulli and Hamilton's energy expressions for fluid conveying welded Galvanized Iron pipe with clamped-clamped boundary condition. A 3D CAD Model was developed in NX-ideas for empty pipe, pipe with fluid flow and welded pipe with fluid flow. Vibration analysis was performed on developed models for 3 mode shapes to generate frequency data using ABAQUS. The developed models were imported in to ABAQUS for generating frequency data. For the welded pipe, effects of weldment at girth welds on the vibration characteristics and stability of pipe was investigated. Results acquired from ABAQUS were compared with theoretical results of natural frequencies and observed the variation of 3% error. Introduction. The fluid conveying pipes are widely used in many industrial applications such as chemical plants, fertilizer plants, nuclear plants and pharmaceutical industries etc. The pipes are subjected to different environmental conditions such as wind forces, earthquakes, and Coriolis forces of fluid flow. Over the last sixty years, extensive studies have been carried out on pipeline systems subject to different boundary conditions and loadings. These pipes however frequently transport fluids from initial point to destination. The subject of piping vibration has attracted a lot of attention from various researchers in recent times due to vast applications.
