This course provides an overview and covers the main topics for process piping requirements according to the B31.3 Process Piping Code: design and fabrication of piping components or piping flexibility analysis process, including practice application of simplified methods and illustration of computer analysis methods. The Code provides requirements for the design, fabrication, examination and testing of metallic piping systems designed for the wide variety of fluid services used in the process industries. Selection of materials, pipe, valves and fittings will be discussed. The candidates will be able to understand the pressure and thermal stress design requirements of ASME B31.3 Code and go beyond the literary words of the Code by explaining the intent of the Code paragraphs and related Code interpretations, where even a close study of the Code on its own may not produce a clear conclusion. This is accomplished with numerous real life practical examples, including many photos of actual plant piping and pipeline situations in many different locations worldwide. These photos enrich the practical approach taken to explain the Code with real life engineering experiences.

By the end of this course delegates will be able to:

  • Explain how to apply Code rules to common design and fabrication situations 
  • Identify pipe stress calculations for various loading situations 
  • Describe inspection and testing requirements
  • Describe the structure and proper use of Section IX
  • Identify welding requirements
  • Explain how to create a PQR, WPS, and WPQ
  • Develop the required skills to review welding documents
  • Use design calculations for various loading situations
  • Identify Inspection and testing requirements
