Corrosion of metals has imposed a serious threat on industry, the society and the nation in terms of both money and manpower. General statistics reveals that overall cost due to corrosion of metals amounts to at least 2-4% of GNP. This loss not only included the cost of replacement of metals, but also the damage to products by contamination, shut down of production, loss of efficiency and in psychological factors associated with failure or explosion of equipments. This loss can be reduced effectively to the tune of 20-25% by the application of appropriate and upgraded knowledge of corrosion and corrosion control science. Present course is an attempt in this direction which includes the basics and applied aspects of diffraction forms of corrosion and introduces to the recent developments in corrosion science and engineering with special emphasis on sour gas corrosion.
Module 1: Basics of Sour Gas Corrosion
HIC and SSC
Module 2: Review of Standards
Understanding of NACE TM0284 - resistance of pipeline and pressure vessel plate steels to Hydrogen Inducted Cracking caused by hydrogen absorption from aqueous sulfide corrosion.
Understanding of NACE TM 0177, EFC 16 and 17 - Sulfide stress corrosion cracking (SSCC) test occurs when a susceptible material is exposed to a corrosive environment containing water and H2S at a critical level of applied or residual tensile stress.
