Metal loss anomalies
All engineering structures contain defects and pipelines are no exception. Metal loss anomalies can be introduced at all stages of a pipeline’s life – during manufacturing, in construction or while in service through material defects, gouges, corrosion, etc. Metal loss anomalies are characterised by an area of pipe wall with a measurable reduction in its thickness.

GE’s inspection capabilities
Specialised inspection capabilities are essential in order to identify and accurately describe metal loss anomalies, and GE offers several proven in-line inspection services for this critical task. The best choice for your situation will depend on the application, type of corrosion mechanism, medium being transported and the nature of the pipeline steel. Since the inspections generate a variety of data forms, special consideration should also be given to your integrity program requirements. Their tools use advanced ultrasonic and magnetic technologies to obtain precise descriptions in the widest range of pipe diameters and wall
thicknesses for gas and liquid pipelines.

Any type of metal loss in a pipeline can be characterised by considering its dimensions. The Pipeline Operators Forum (POF) has established a graphical representation of a number of common metal-loss features, as shown below.

GE’s worldwide fleet of in-line inspection tools has an unmatched breadth and depth of data-collection and analysis capabilities to address all types of metal-loss threats to your pipeline.

In order to determine the best tool for the job, operators need to consider three things:

• The level of accuracy required
• Defect types to be identified
• Operation and pipeline characteristics

The value of these tools does not simply end with data collection. The level of information provided, combined with their advanced analysis capabilities, will help you more accurately determine the risks involved in each case and substantially reduce the number of excavations necessary for direct assessment and repair.

By incorporating all data into a long-term integrity management process, they (GE) can perform ongoing data analysis services or provide you with the advanced, user-friendly software tools to complete the work internally – giving your staff more access to complete information, and more control over the future integrity of your pipeline.

Protect the future of your pipeline by GE
They provide a comprehensive range of metal-loss detection services for pipeline operators. Our inspection tools draw on an unparalleled history of technological innovation and in-field success. They have accurately and consistently identified anomalies of every type and
size, in every kind of pipeline. And the information they gather helps you move beyond detection – to enhanced long-term safety and productivity.
