Materials of Construction for Process Equipment

12-01-2020 - 16-01-2020 4200 كوالا لمبور


Course Introduction:


Appropriate material selection is the cornerstone of pressure equipment and piping design, operation and maintenance. The acceptability of materials is controlled by the relevant Codes. The mechanical integrity, safety, and cost-effective operation of plants depend on the in-service performance of the materials of construction throughout the plant life cycle.


This seminar provides comprehensive and practical understanding of engineering materials and guidance on the methods and best industry practices for the selection of the appropriate materials of construction for specific applications while simultaneously satisfying service requirements, construction Code requirements, and least life cycle costs over the entire plant life. This seminar will provide a practical overview of ASME BPVC Section II – Materials, as well as some relevant information from the BPVC Section VIII Div.1 and B31.3 Process Piping.


Course Objectives:


Upon successful completion of this course, the delegates will be able to:

  • Perform the methods of building construction
  • Understand appropriate selection of materials of construction for pressure equipment
  • Understand how materials affect safe, reliable and cost-effective plant operation
  • Enhance awareness of key requirements of relevant design and operation standards and industry practices such as ASME B&PVC and B31.3; ASTM Material Specifications, API 571, 580, 581, 578 and 579, and others
  • Identify and locate in-service degradation and appropriate tools for condition assessment and making sound run/repair/replace decisions
  • Recognize that although all flaws detected by inspection must be evaluated, not all flaws need to be repaired
  • Apply the standard of API Std 579-1/ASME FFS-1 for fitness-for-service assessment may obviate the need for some repairs and result in reduced maintenance cost and downtime


Who Should Attend?


This course is intended for refinery, petrochemical and process plant mechanical, process engineers, project and consulting engineers, technical professionals, inspectors, maintenance personnel, engineering and Technical Personnel involved in plant mechanical integrity and reliability.
