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.

Who Should Attend?

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

 

Course Objectives:

   At completion of this 5-day course, the participants will be have an in-depth understanding of the ASME B31 design, construction, inspection and testing rules; as well as their application to integrity assessment of operating systems.

   The participants will gain an in-depth knowledge of pipe and fitting material specifications, fabrication process and influence on mechanical properties of strength and toughness, to help in material selection and failure analysis.

   The participant will understand the technical background to the design equations, and their application to the design of piping systems and pipelines. The course addresses rules of good practice in layout of piping systems for reliable operation. The course provides an in-depth, step-by-step review of operating transients in piping systems and pipelines, their cause, and the methods for their analysis.

   The course covers construction and welding practices, weld inspections, weld flaws and acceptance criteria. The course covers hydrotesting methods and alternative leak detection techniques.

   The participant will gain a practical understanding of piping and pipeline corrosion mechanisms, how to recognize them, classify them and resolve them.

     

   The participant will be introduced to the latest techniques and research in piping and pipeline integrity to analyze a degraded condition due to either corrosion or mechanical damage.

 

   The participants will review case histories of field failures and will evaluate their cause and solutions to avoid recurrence.
