Introduction,ponsibility of which depends on plant personnel. However, indirectly it largely depends on how the plant has been built with respect to material selection, engineering design and proper supervision during fabrication and construction activities. The plant personal has to ensure the reliability of th

Classification of Metallic Engineering Materials,uirements to be considered as the most suitable engineering material. Amongst metals, the largest use in the petrochemical industry is of ferrous metals and alloys like carbon and low alloy steels and stainless steels. Once selected, it is necessary to finalize the material specification as per requ

Structure of Metals and Alloys,est of which is called a crystal. Most of the metals solidify in three crystal forms of face centered cubic (f.c.c.), body centered cubic (b.c.c) and close packed hexagonal (c.p.h.). The crystal undergoes no change till it melts except in some cases like iron where changes before melting occur in th

Mechanical Behaviour of Metals and Alloys,rties. Under the influence of stress metal undergoes deformation and finally fails in ductile mode. Deformation occurs by sliding of atoms along slip planes under the influence of stress and by movement of dislocations. Any hindrance in dislocation movement would increase the strength and this princ

Heat Treatment,he treatment is most significant for ferrous materials because the phase transformation from austenite to ferrite can be controlled as the process involves nucleation and growth, which is reflected in time temperature transformation (TTT) curves of different alloys. The time being an important facto

Material Degradation, is degradation of material due to metallurgical changes. Corrosion is an electrochemical process and there are many forms of damage, important amongst which are uniform corrosion, galvanic corrosion, stress corrosion cracking and pitting and crevice corrosion. These modes of damage affect the usefu

The rate is also affected by characteristic of produced water, flow rate, oil/water ratio, oxygen, etc. Number of predictive models have been developed which have been classified as mechanistic or empirical. However, the predicti
