A333 Grade 6 Low Carbon Steel in Pipelines – Microstructural Characterization and Hardness Properties

M. N. Ervina Efzan*, S. Kesahvanveraragu, J. Emerson   1.0 INTRODUCTION 1.1 Offshore Pipeline Material Pipelines in offshore platform are made up of various types of materials. Selection of material relies upon certain considerations such as cost, functional requirement, operating conditions of pressure and temperature, corrosion rate and so forth [1-2]. Since there are varieties of pipelines in offshore platform, material selection and those considerations are highly required. In offshore industry, metal is the highly used material that can be assorted into ferrous and non-ferrous metals [1-3]. Metals containing iron (Fe) as their premier composition are known as ferrous metals, whereas metals containing other elements are termed as non-ferrous […]
