 Pipeline and Piping Inspection, Maintenance, Repair, Management and Integrity to ASME B31 (O9285) QR Code

Pipeline and Piping Inspection, Maintenance, Repair, Management and Integrity to ASME B31

Overview:

Introduction:

A five-day course on the practical aspects of piping and pipeline design, integrity, maintenance, and repair. The participants will obtain an in-depth understanding of the ASME B31 code rules and API standards, their technical basis, and practical application to field conditions.

The course reviews and applies the ASME code design rules, strength, and fracture design analysis and acceptance criteria.

The participants will be able to recognize causes of degradation in-service, whether mechanically induced (pressure, vibration, fatigue, pressure transients, external damage) or due to corrosion (wall thinning, pitting, cracking), and apply integrity analysis techniques to make run-or-repair decisions.

The participants will review inspection techniques, from the most common (PT, MT, UT, RT, MFL pigs) to most recent (AE, PED, UT pigs, and multi pigs), and the implementation of integrity management programs, periodic inspections, and evaluation of results.

The course will review the various repair techniques, their advantages and shortcomings, and the step-by-step logic to be followed in making repair decisions and selecting the applicable repair.

Course Objectives:

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

  • Explain the many prevention and detection practices to ensure pipeline safety
  • Describe how the use of certain prevention and detection practices from the ASME B31.8S Standard, as well as 49CFR192 regulations, interact for improved performance and ensure maximum safety
  • Specify prevention and repair solutions for each threat and improve the IMP performance for gas pipelines
  • Explain the reasons why one prevention and repair solution may be better than another; or why both together can be even more effective

Targeted Audience:

The course is intended for engineers, maintenance technicians, and inspectors responsible for the design, integrity, maintenance, and repair of pipelines and piping systems.
