Oxide Scale Measurement of for boiler tubes

About Oxide Scale Measurement of for boiler tubes

Asignificant limiting factor that affects tube life in fossil fired steamboilers is the growth of iron oxide scale (magnetite) on the inside and outsidetube surfaces. The oxide scale, which forms under long term exposure to veryhigh temperatures, acts as a thermal insulator. While external scale limitsheat transmission into the tube and reduces boiler efficiency, internal scalebuildup represents a potentially more serious problem. The insulating effect ofinternal scale limits heat transmission into the water vapor inside the tube,which in turn causes chronic overheating of the tube wall and promotesaccelerated metallurgical failure. Non Destructive measurement of internaloxide scale thickness is of major interest in the power generation industry andother users of fossil fuel steam boilers, since scale thickness may be used topredict remaining tube life. While very high frequency ultrasonic gagingtechniques have been available for this measurement for a number of years, theyinvolved use of cumbersome, expensive pulser/receiver and oscilloscope systems.Recent advances in instrumentation technology have made available small,hand-held ultrasonic gages with software optimized for measurement of internalscale and advanced data logging capability. Additionally, the use of normalincidence shear wave transducers improves resolution of thin scale layers,permitting measurement of scale buildup down to approximately 0.125 mm withhand-held equipment. ITE has uses Olympus 38 DL plus with suitable probes fortesting of tubes for deposition of oxide scales. We have been providing theseservices for more than a decade and have various customers across the countryin Power Sector who regularly use our services.

Advanced Measurement Technology

Employing either magnetic induction or eddy current probes, this instrument delivers highly accurate oxide scale thickness measurements (05 mm) with a rapid response time of less than two seconds. The device also features automatic zero and span calibration, ensuring reliable and reproducible results even in challenging industrial conditions.


Versatile and Reliable in Tough Environments

The devices robust build, IP54 protection, and shockproof carry case enhance its durability for industrial settings. With an operating temperature range of 050C and measurement capability up to 600C, it endures in high-heat environments common in boiler operations. Its portable form factor and moisture resistance ensure seamless field usage.


Intuitive Interface and Flexible Data Management

The backlit digital LCD display provides clear readouts in low-light situations, while the memory can store up to 1,000 readings. USB and serial communication (RS232/RS485) streamline data transfer and documentation. The visual and audible alarms quickly notify inspectors when oxide scale thickness exceeds preset limits, boosting safety and maintenance efficiency.
