This course is held online over 3 days on the following schedule (All times in Eastern Time Zone):

10 am to 6 pm Eastern (Will include the usual breaks)

Please note that we also have the online course, 15-1101-ONL24 Design of Industrial Pressure Piping to ASME B31.3-Practical Examples, scheduled for November 26-28, 2024, which will focus on the design aspect.

This course is part of a two-part Series: Industrial Pressure Piping Code. The topics in this series include:

You can register for any of these courses or register for the series and save 20%.

After participating in this course, you will be able to:

  • Understand all the requirements of ASME B31.1 and ASME B31.3 (relevant interpretations included)
  • Perform an overview of calculations to determine the minimum wall thickness of all piping system components according to associated external loads (pressure, hydrostatic test, water hammer, etc.).

A piping system is a set of pipes and other components (valves, elbows, etc.) used to transport fluid from point A to B. ASME B31.1 (Power Piping) and ASME B31.3 (Process Piping), recognized by the Canadian Pressure Equipment Code CSA B51 (Boiler, Pressure Vessel, and Pressure Piping Code), contain all requirements for industrial pressure piping. These codes are used in oil refineries and terminals and various industries such as chemical, pharmaceutical, textile, pulp and paper, and cryogenics. ASME B31.1 is mainly associated with high-pressure steam boilers.

These ASME Codes establish the requirements for materials, design, manufacturing, assembly, inspection, and certification of pressure piping pressure.

Course Outline:

  • Overview of main Canadian regulations on pressure piping
  • Description of responsibilities of key stakeholders and required qualifications
  • Requirements for materials (impact testing, etc.)
  • External constraints to be included when designing piping
  • Manufacturing requirements (welding, preheating, heat treatment, etc.)
  • Requirements for visual inspection of welds
  • Tightness test requirements (hydrostatic, pneumatic, sensitive leak test, alternative leak test, etc.)

Who Should Attend
Engineers • Inspectors • Technicians • Contractors • Professionals in the industrial pressure piping field

Day 1

  • Definition of a pressure piping system (according to certain Canadian provinces)
  • The boundary between a reservoir and a pressure piping
  • Requirements (overview) regarding piping in Canada, CRN, etc. (CSA B51)
  • The limits of codes (ASME B31.1 and ASME B31.3)
  • How to find information in the ASME Codes
  • Definition of the different fluid categories of ASME B31.3 (Normal, D, M, High Pressure, Elevated Temperature, Severe Cyclic, and High Purity) and the difference between BEP (Boiler External Piping) and NBEP (Non-boiler External Piping) for ASME B31.1
  • Description of the responsibilities of main parties and minimum qualification requirements for each of them
  • Standard vs. non-standard components
  • Material requirements (including lower temperature limit calculations to verify if impact tests are required)

Day 2

  • External constraints to be included in the piping design
  • Definition of pressure and temperature design
  • How to determine the pressure and temperature design based on operation data
  • Under what conditions can we authorize pressure/temperature upsets above design limits?
  • Requirements for protection against overpressure
  • Hoop stress formula to determine the minimum required thickness of a pipe having an internal pressure
  • Type of pipe supports (MSS SP-58, MSS SP-69, and MSS SP-127)
  • Trunnion
  • The formula for piping bends (intrados and extrados)
  • The formula for mitre bends
  • Branch connection opening calculations and examples

Day 3

  • Calculations of flat covers (blank and blind flanges)
  • Expansion joints
  • Overview of ASME B16.5 and ASME B16.47 requirements
  • Calculations of equivalent pressure (external axial force and moment) on standard flange
  • Manufacturing requirements (welding, preheating, heat treatment, hardness test, etc.)
  • Weld defect tolerances
  • Leak test requirements (hydrostatic, pneumatic, sensitive leak test, initial leak test, alternative leak test, etc.).
  • Additional requirements on welds made without hydrostatic test (closure weld)

Appendices (will be covered only if time permits): ASME B31.3 History Water hammer calculations Piping provided with internal refractory: equivalent elasticity modulus (E) calculations Pipes having an external pressure (vacuum) and examples.
