Design and Analysis of Buried Pipe for Pressure Loads

Abstract

Generally Buried pipe was made up of steel and GRP. Different papers are published based on the Glass Reinforced Polymer(GRP) pipes. The papers focused on the stress developed on the GRP pipes. Buried Pipes undergoes corrosion due to Pressure. The project is aimed to need for lighter and more corrosion resistant components.

                The aim of the project is to analysis the pipe for Eglass/Epoxy and Carbon/Epoxy by replacing GRP. Eglass Epoxy and Carbon Epoxy are considered based on their better material properties. These materials possess less weight and high corrosion resistance same as GRP. In this project, at first 3d modelling of the buried pipe is modelled using NX-CAD software. Next, 3d model of buried pipe with rectangular soil and circular soil was analyzed in ANSYS software.  Buried pipe is analyzed for external pressure caused by soil and internal pressure caused by fluid. From the analysis best model is considered and used for further analysis. In further analysis, orientation of layers is considered for two composite materials. Comparison was done to determine the best material from Eglass Epoxy and Carbon Epoxy. Analysis is done for steel material and then follows for Eglass Epoxy and Carbon Epoxy.
