Pipe Thickness Calculation Under External Design Pressure or Vacuum Condition

Course Objective

The objective of this course is to provide participants with a clear understanding of pipe thickness calculation under external design pressure and vacuum conditions in accordance with international codes and standards (e.g., ASME BPVC Section VIII, ASME B31.3). By the end of the course, learners will be able to:

• Understand the fundamentals of external pressure loading and vacuum conditions in piping systems.

• Identify scenarios where external pressure governs thickness design.

• Apply code-based formulas, charts, and methodologies to determine safe pipe wall thickness.

• Recognize stability concerns such as pipe buckling and collapse under external loads.

• Develop competency in performing practical calculations for real-world piping applications.

Subject Description

This specialized course focuses on the mechanical design of pipes subjected to external pressure and vacuum conditions, which are critical in industries such as oil & gas, petrochemicals, power plants, and marine applications. Unlike internal pressure design, external pressure introduces the risk of instability and collapse, making its analysis vital for safe and reliable piping design.

The course covers:

• Introduction to external pressure concepts and vacuum conditions in piping.

• Applicable codes, standards, and design criteria.

• Use of ASME external pressure charts and formulas.

• Example Calculation procedures.

• Case studies and problem-solving exercises to reinforce learning.

By integrating theory with practice, the course equips engineers, designers, and technical professionals with the necessary skills to ensure piping integrity under external loading conditions.
