AMCO Integrity tube failure services can help plants people to improve boiler tube reliability and avoid costly outages.
AMCO’s expertise and experience can determine the root cause of tube failure with both in situ and laboratory analysis – and provide the remedial action and recommendations to solve tube failure.
Our applicable capabilities include, but are not limited to root cause analysis, metallurgical analysis, visual inspection, deposit weight density determination, chemical composition, wall loss determination, scale thickness measuring, pit depth measuring, mechanical failure analysis, and more.
Our assessing process determines failures by corrosion, stress ruptures, erosion, fatigue and/or maintaining quality control. As a preventative measure potential failures may be identified to avoid costly repairs and lost production.
Tube analysis and evaluation includes:
- Metallurgical evaluation plan
- Visual, non-destructive testing and as-received photo documentation
- Dimensional measurements on ring samples
- Material verification
- Metallographic specimen evaluations
- Hardness testing
- Internal scale and deposit characterization
- Steam-cooled tubes – determine steam side scale thickness and morphology
- Water-cooled tubes – determine the chemistry and deposit weight
- Analysis of data and report
- Cause of tube failure
- Remaining creep life
- Current tube conditionRemaining creep life
- Operational change
- Water chemistry changes
- Chemical cleaning
- Tube replacement
- Design changes
- Additional analysis
Prevent failures before they occur:
Tube assessment isn’t just a case of waiting for failures to happen.
AMCO can help identify key areas and develop inspection programs. Regular condition assessments can help identify potential problems and eliminate them before failure can occur.
Our unique expertise in probabilistic assessment means that you would need to inspect, check and repair or replace lesser number of tubes than under a deterministic assessment which is what most consulting companies or OEM’s will be able to offer you. This will of course help you with saving costs and increasing profitability.
At AMCO’s, we keep up-to-date with the latest research into damage mechanisms and new materials, so our clients receive the most accurate evaluations of problems and the best possible solutions that meet their requirements.
Our partner is one of the European leaders in specialist areas such as application of defect and probabilistic assessment of plant integrity. They wrote a detailed guidelines on Boiler Tube Failure (BTF), please feel free to contact us if you need this guidelines.
