Failure Analysis and Pipeline Corrosion Assessments
Cormetrics lab facilities are custom suited for failure analysis and corrosion assessments. We perform corrosion analyses ranging from downhole failures, production pipelines, facility piping and more. With our in-house equipment and expert knowledge & experience we can accommodate all your failure and corrosion assessment needs.
OUR CAPABILITIES INCLUDE:
A detailed examination behind the causes of failure within a sample (pipes, joints, tubing, valves etc.). It involves the dissection and cleaning of the sample received for documentation of the corrosion activity.
Our standard reports include the following:
- System Description: This includes operating conditions, flow characteristics/modelling, production volumes, gas/liquid hydrocarbon analyses, system history and any other relevant information.
- Water Chemistry: Discussion of water analysis, including scaling and corrosion tendencies- Validity of the water analysis is checked.
- Sample Description: Description of sample as received including measurements and digital photographs as well as any other significant observations prior to any analysis being performed.
- Sample Examination: Detailed description of all analysis performed in the laboratory including any spot tests and observations during and after cleaning of wall scale and corrosion products. Inhibited acid cleaning is used to preserve the fine details of the corrosion damaged surface. Mechanical properties of the sample as well as micro-structure may be checked to ensure the material meets the expected specifications.
- X-Ray Diffraction Analysis: Any significant/relevant scale and corrosion product will be sampled and analyzed by XRD. Identification of the nature of solids associated with a failure is often critical to understanding corrosion modes.
- Degradation Mechanism: A detailed discussion of the root cause(s) of the failure and of any contributing factors will be presented. The role played by system parameters, operating methods and mitigation practices is usually discussed.
- Conclusions & Recommendations: Clear and concise statements of conclusions are presented. Considering restrictions of the system, recommendations are made to avoid occurrence of further failures.
SAMPLE REPORT
Corrosion assessment of a pipe segment(s) or other metal sample will document the as-received condition. Assessments entail splitting and cleaning of the sample to allow detailed documentation of the type and extent of corrosion activity. Additional testing, such as scale analysis, can be performed as needed.
SAMPLE REPORT
Corrosion assessment of a pipe segment in comparison to the In-Line Inspection (ILI) data will document the as received pipe condition and extent of corrosion activity in comparison to reported ILI data. Activity entails splitting and cleaning of the pipe sample to allow documentation of corrosion activity.
Additional testing capabilities include:
- ATP analysis – quantitative analysis of active microbes in solid and liquid samples
- Copper Ion Displacement Test – visual analysis for gaps in inhibitor film through copper plating
- Magnetic Particle Inspection – visual analysis for crack features
- Liquid Penetrant Inspection – visual analysis for wall crack features
- Ultrasonic Thickness Measurement – measurement of remaining wall thickness
- Coating Thickness Measurement
