Process Equipment & Piping Systems: Application, Design, Operation, Failure Prevention & Repairs




Introduction:

Process equipment and piping systems constitute the major portion of plant assets and their integrity and reliability are essential for plant availability and performance. Many process equipment and piping systems are subjected to hazardous service conditions and damage mechanisms which, if not adequately monitored and assessed, could result in major failures with consequential significant injuries and business losses.

It is essential to inspect the process equipment and piping system to detect any damage, characterize it, and assess its impact on the equipment integrity. With so many pieces of equipment and extensive piping systems and networks, it is impossible to inspect every piece of equipment or piping in a plant. Therefore, an approach based on criticality, i.e. risk-based, taking into consideration the damage mechanisms and failure risk must be taken

Targeted Groups:

  • Process, Mechanical and Chemical Engineers
  • Operation and Maintenance Engineers
  • Project Engineers
  • Supervisors and Managers
  • Technical Personnel involved in inspection

Course Objectives:

At the end of this course the participants will be able to:

  • Understand that the mechanical integrity of process equipment depends jointly on the proper design, operation, condition assessment, and maintenance of the equipment.
  • Understand the degradation mechanisms that process equipment could be subjected to over their operating life, how to identify them, predict and determine their impact, and what appropriate measures can be taken to prevent and control the resultant damage.
  • Gain knowledge and failure analysis skills they need to conduct damage and failure analysis to prevent similar failures from happening

Targeted Competencies:

  • Working knowledge in the mechanical design of pressure equipment and piping systems.
  • The inter-dependence of design, operation, and maintenance for achieving mechanical integrity of pressure equipment and piping systems.
  • Understanding, prediction, and identification of degradation and damage mechanisms that affect process equipment fitness for continued service and could result in significant potential failures.
  • Application of risk-based inspection - API 580.
  • NDT methods and their effective application.
  • Performing fitness-for-service assessments - API 579.
  • Failure investigation techniques and root cause analysis.
