Over a span of 30 years and more than 5 million wall thickness measurements, certain ultrasonic pipe testing investigations still stand out as significant. Test results can go either way, and in many examples we are very pleased to report a limited corrosion problem requiring only minor repairs. As damages and cost escalate, however, other factors and complications often arise.
Below are some true case histories relating to our work in this field. During the couse of most fitness for service piping evaluations we also encounter other aspects of the building operation critically important to the conditions which exist – such as the water filtration, corrosion control, plant design, etc, No names or locations are provided, and minor insignificant details have been changed for the obvious reasons.
