Internal Corrosion for Pipelines Advanced

Introduction

This course focuses on the monitoring techniques and mitigation strategies required to assess internal corrosion and develop and manage internal corrosion control programs. Data interpretation, analysis, and integration, as well as criteria for determining corrective action for high-level internal corrosion problems within a pipeline system, will be covered in detail. The Internal Corrosion for Pipelines course introduces the fundamentals of implementing, monitoring, and maintaining an internal corrosion control program as part of an overall pipeline integrity management program. It is an introductory level course focusing on internal corrosion of liquid and natural gas pipelines used for transmissions, storage, and gathering systems.

Objectives

Determine if internal corrosion exists by evaluating a set of criteria to identify and apply monitoring techniques such as:

• Corrosion coupons
• Electrical field mapping
• Ultrasonic testing
• Linear polarization and electrical resistance probes
• Hydrogen and microbiological monitoring
• Identify the types of corrosion, influencing key environmental variables, and methods to control corrosion
• Monitor corrosion through devices and tests, including analysis of gas, liquid and sludge/solid samples, coupons, and electrical probes
• Examine exposed surfaces and be able to determine the root cause of corrosion
• Proper selection of mitigation methods such as:
  • Chemical treatment by biocides and corrosion inhibitors
  • Facilities maintenance including the use of pigs, clearing drips, and clearing valves
  • Internal coatings
  • Cathodic protection only for internal protection of tanks
  • Facility design considerations
• Perform integrity assessment methods including internal corrosion direct assessment, in-line inspection, and hydrostatic testing

Properly select inspection techniques including:

• Visual Inspection
• Automated Ultrasonic Testing (AUT)
• Magnetic Flux Leakage
• Guided Wave Ultrasonic Testing (GWUT)
• Manual Ultrasonic Testing
• Eddy Current (EC)
• Ultrasonic Testing (UT)
• Radiographic Testing (RT)

Determine when mitigation is required and the appropriate mitigation methods to utilize including maintenance pigging, physical design changes, and operational modifications

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. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

Individuals responsible for the management of internal corrosion control program for pipeline systems including:

• Implementation
• Maintenance
• Engineering

Prerequisites Required

There are no required prerequisites for this course.

Exam information

The written exam is delivered via computer-based testing (CBT) and is scheduled separately from the course. A voucher for the CBT is included as part of the full-course registration price.
