MATERIALS OF CONSTRUCTION FOR OIL & GAS INDUSTRIES

OVERVIEW

Description

This course explores all of major categories of materials while offering detailed guidance on material selection for the various service environments encountered in oil refineries and petrochemical plants. In any process plant in oil and gas industry like Refinery, Petrochemical plant etc. the process equipments, piping and tanks form the vital part of the installation. The success or failure of any of such process plants depends on whether the correct materials are used for manufacturing these equipments. The materials must be suitable for the required process, the corrosive conditions, temperature considerations etc, and should last the expected design life. This should be achieved at the optimum cost keeping in view safety and reliability considerations and meeting the codes and standards for the materials.

The theme throughout the course will be focused on how to put the right material in the right place in the right way. Practical guidelines in selection of materials against many forms of corrosion will be presented. The participants also will understand the basic metallurgy of iron-carbon and other complex alloy systems and predict their physical, chemical and mechanical properties, so that one may be adequately equipped to select and specify the most appropriate alloy grade for a particular engineering application. The attendee is treated to the major ASTM specifications and selection of their common equivalents in BS, JIS,DIN specifications, including Do’s and Don’t in selecting material substitutes. The course also covers methodology of the Unified Numbering System and Index to UNS Designations by Base Elements.
