Monitoring process equipment operating at high temperatures can be very challenging. Piping, vessels, and other mechanical equipment are typically insulated to minimize heat loss. Surface conditions can be difficult for NDT technicians to properly couple ultrasound probes and obtain reliable thickness reading as couplant can quickly vaporize at those high temperatures.
With minimal surface preparation (typically use of a file on an area the size of a nickel), the sensor can be affixed to the component using a variety of simple clamping systems, brackets, or fixtures. Installation of the sensor is as simple as tightening a few bolts until a metal-to-metal seal is achieved which is made possible using a thin and pliable metallic foil as the couplant. Beginning to end, the installation process shouldn’t take more than 30 minutes per sensor. After the probe is mounted, thickness measurement is consistently made at the same location every time. This eliminates the variability typically experienced with manual ultrasound thickness measurements.
Sensor Networks Ultra-High-Temperature ultrasound probes are designed for continuous coupling to equipment with surface temperatures up to 932°F (500°C). The probe(s) can be connected to smartPIMS® which are a multi-point approach to corrosion monitoring or fully-wireless microPIMS® single-point sensors for thickness measurements with a resolution of 0.001”/ (0.025 mm)
Utilizing the Ultra-High-Temperature transducer’s accompanying temperature sensor, thickness readings may be temperature corrected thus providing an added level of accuracy to the thickness value especially during start-up, shut-down and equipment upsets.
Sensor Networks’ Ultra-High-Temperature ultrasound probes can dramatically increase the consistency of data (i.e. thickness values), eliminate the repeated manual labor involved not only with accessing the location, but also removing / re-insulating, and actually performing the data collection. Perhaps most importantly, the sensors eliminate the cost and risk of obtaining thickness data in difficult-to-access locations or areas where human safety and cost to access is significant.
Typical Installations include: Overhead Crude Lines, Steam Lines, Cracker Units, Post-Furnace Circuits, High Temp Slurry Lines, Distillation and Regeneration Vessels & associated piping.
