Piping Systems and Pipeline integrity With An Application of ASME B31 Codes

Introduction

This course comprises two sections.

The first examines the design requirements for process plant piping systems. The second section examines the maintenance requirements for these systems. In each case, the course goes beyond merely repeating the material contained in the governing standards. It discusses practical applications and typical procedures. The course also contains sample problems that are put together with written exercises for you to complete.

Objectives

After completion of the course the participants will be able to:

• Understand the total structural integrity of process plant piping systems throughout their useful life
• Discover how the ASME B31.3 code has been correctly and incorrectly applied.
• Ensure the total structural integrity of process plant piping systems throughout their useful life.
• Discuss and apply the design requirements of the ASME B 31.3 Code.
• Achieve higher levels of maintenance excellence in refineries and other process plants.
• Examine and apply the maintenance and inspection requirements of API 570 to process plant piping systems.
• Perform engineering audits of designs and procedures

Training Methodology

The training methodology is interactive with group exercises and is suitable for all employees involved in functions management. The pace and level of the training workshop is customized to the understanding of the delegates. Ongoing back-up and support is available after the training on request to the supplier, and the training course is also available for in-house presentation as well as for “Competency Transfer”.

Who Should Attend?

Engineers, chief Engineers, Maintenance Engineers, Plant Engineers, Facilities Engineers, Mechanical Engineers, Inspection Engineers, Process Engineers, Design Engineers, Planning Engineers, Operations Engineers, Corrosion Engineers, Structural Engineers, Reliability Engineers & Integrity Engineers.
