ANALYSIS OF GRE PIPES WITH EPOXY RESIN COMPOSITE MATERIAL AND MATERIAL TEST SPECIFICATION

Abstract

At present scenario composite materials has been extensively used in variety of fields right from house holds to aircrafts for its superior properties like lower specific weight, strength to weight ratio and modulus to weight ratio. In this project effort has been made to extend its application to pipes. Conventional pipes have its own disadvantages such as higher specific weight, low corrosion resistance and low strength which can be replaced by the composite pipes .Design of composite pipe has been done as conventional pipe for its inner diameter and its wall thickness. Structural analysis has been made with ANSYS 12 for its deformation and stress. Comparative study of ANSYS results for M.S.PIPES, and GRE pipes were done to justify the usage of GRE pipes.Filament winding process has been adopted to manufacture GRE pipes in a conventional lathe by implementing a winding setup. Hardness test and compressive test of GRE pipes to be done to assess its strength, leak and corrosion test for its ability to carry liquids.
