Optimizing Materials Technology and Selection to Increase Plant Reliability - Session 2 - STG 36
Wednesday, March 19 - 8 a.m. to 4:10 p.m. This symposium contains technical papers focusing on the use of materials technology and materials selection to prevent unexpected failures. Papers will contain information describing the use of materials technology and corrosion resistant materials that mitigate various forms of aqueous and high temperature corrosion in chemical and petrochemical plants. The goal of this symposium is to increase plant reliability, reduce inspection frequency, and move towards a maintenance-free; inspection-free, environment consistent with the Risk Based Inspection philosophy.
