Product Usage Instructions
Elevated Temperature Inspection:
When conducting elevated temperature inspections, it is important to consider
the thermal gradients inside the wedge. These gradients can lead to variations
in temperature-dependent wave velocity and skewing of the waves. To overcome
these limitations, utilize software simulation of focal law algorithms
combined with careful experimental validation. This approach has been proven
to be reliable and accurate.
FAQ (Frequently Asked Questions)
- Q: How can I ensure accurate results during elevated temperature inspections?
A: To ensure accuracy during elevated temperature inspections, make sure to account for thermal gradients inside the wedge and use software simulation to validate the results.
Dacon inspection technologies, now provide PAUT services both for weld testing and corrosion mapping for pipelines and pressure vessels for up to 350° degree Celsius.
PAUT CORROSION MAPPING
Wlith the same accuracy as inspecting at ambient temperatures to find
remaining wall thickness.
PAUT WELD SCANNING
Form simple butt welds to less accessible flange surface can be inspected with precision accuracy.
Benefits
Interruption of plant operation can be avoided if NDT inspections can be
performed on-line at operating temperatures; this may be done up to 350° C
using PAUT. This capability avoids costly downtime and reduces the risk of
damage from thermal cycling associated with periodic shutdowns. These elevated
temperature inspections provide accurate method of monitoring known flaws, and
detection of new flaws without removing the vessels from service with high
degree of repeatability, thereby actualizing significant cost savings.
Elevated Temperature Inspection
At elevated temperatures, thermal gradients inside the wedge lead to
variations in temperature-dependent wave velocity and skewing the waves. Using
software simulation of focal law algorithms and through careful experimental
validation, these limitations can be overcome and has been proven to be
reliable and accurate.
