Oxide Scale Measurement Services
What Is It
Know the True Condition of Your Boiler Tubes
IRC Engineering’s ultrasonic Oxide Scale Measurement service reveals the condition of boiler tubes from the inside out - without tube removal or guesswork.
High-temperature boiler tubes naturally develop magnetite scale on their inner surface as steam reacts with steel. As scale thickens, tube-wall temperature rises, accelerating scale growth and metal damage.
Left unmonitored, this buildup is a leading cause of boiler tube failure.
Why Oxide Scale Measurement
Why Oxide Scale Measurement Matters
Early Warning
Scale buildup below roughly 0.3 mm has minimal impact; beyond this point, damage can accelerate rapidly.
Remaining Life Insight
Regular measurement helps estimate remaining tube service life with confidence.
Planned Maintenance
Identify tubes approaching failure and replace them during a planned shutdown.
No Tube Cutting
Avoid physically cutting tube samples for laboratory analysis, saving time and money.
How It Works
How We Measure It
Using advanced ultrasonic thickness-gauging equipment, our technicians measure oxide scale thickness without cutting a sample from the boiler.
Ultrasonic Testing
A sound wave is sent through the boiler-tube wall.
Signal Measurement
The time difference is measured between reflections from the steel-to-scale interface and the tube’s inner surface.
Scale Thickness Calculation
This measurement allows accurate calculation of internal oxide scale thickness.
Our Technology
Ultrasonic Oxide Scale Measurement
A non-destructive method for assessing internal magnetite-scale buildup in boiler tubes.
Our approach helps reveal internal tube condition accurately, without tube removal or laboratory sample cutting.
