Program Description

This special course entitled “Piping Design and Flexibility Analysis” addresses piping system design aspects such as the determination of the pipe wall thickness for the internal pressure, as well as external pressure based on the ASME B31.3 code and selection of proper schedule number from the ASME B36.10M and B36.19M standards, and selection of pressure and temperature ratings (classes) of flange and valve by referring appropriate standards along with materials for the piping systems for a given process service and operating conditions. Also covered PFDs, P&IDs, General Arrangement Drawings (GADs), Piping Isometrics, and legends used in industry. The flexibility of a piping system is a major issue, and it is dicey if the piping system doesn’t have inherent flexibility. Hence, pipe stress analysis and performing flexibility analysis using industry-accepted pipe stress analysis software are covered. Pipe supports, hangers, expansion joints, good practices, design of jacketed piping, vibration, pipe insulation, Underground (Buried) piping, challenges that arise from corrosion and land sliding, remedial solutions, and cathodic protection to prevent the buried pipe are discussed.

Course Objectives:

  • To explain the difference between pipe and tube, pipe size identification, pipe schedule numbers, and select pipe dimensions from ASME B36.10M and B36.19M standards and determination of pipe wall thickness and final selection of pipe schedule number, and flange and valve class (pressure-temperature rating)
  • To explain the types and classification of loads, induced stresses, and fatigue, and solve the induced stresses in piping systems analytically and perform flexibility analysis of a medium to complex piping system using industry accepted CAEPIPE software
  • To explain the primary and secondary supports, types of primary supports and hangers, vibration in a piping system and its effect, purpose of expansion joints, types, need for jacketed piping, design jacketed piping, thermal expansion of the buried pipe, ground movement, and cathodic protection for a buried pipe from corrosion
