Pipeline and Piping Design, installation, Operation, inspection, Testing, Maintenance, Repair, FFS, Pigging, integrity and Rehabilitation (ASME B31 and API 579 Standards)

Introduction

Covers natural gas and practical aspects of gas transmission, 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 participant in this integrated and comprehensive course will learn to apply the rules of the API/ASME 579 standard "Fitness-for-Service" to evaluate the integrity and remaining life of pressure vessels, storage tanks, piping systems and pipelines, to make cost effective run-repair-replace decisions, and select the appropriate repair options.

Objectives

In this program you will learn:

• Fundamental principles of fitness-for-service, their practical application through case histories, and a step-by-step evaluation process for each type of degradation mechanism
• The basic design of pressure vessels, piping and storage tanks, fundamental principles of component integrity, application of the ASME code rules, material properties of strength and toughness, and the introduction to stress and fracture mechanics
• A review of degradation mechanisms and the application of API/ASME 579 to brittle fracture, general metal loss, local wall thinning, pitting, blisters and laminations, mechanical defects (dents, gouges, misalignment, and distortion), crack-like flaws (stress corrosion cracking, weld flaws, crack-like defects), fatigue, HIC & SOHIC and fire damage

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.

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
