Preventing Costly Boiler Failures with RTI
Boiler wall tubes suffer from many forms of degradation while in service. Water wall tubes can suffer from hydrogen damage, pitting, ash and soot blower erosion, graphitization, under-deposit corrosion, thermal fatigue and more. Without the proper tools or inspection protocols in place, such issues can quickly compromise the integrity of the tubes, leading to costly shutdowns and disruption to the entire boiler. Whether degradation is caused by highly aggressive environmental conditions or stresses caused by external loads or uneven cooling throughout the system, knowing the condition of your boilers saves time, money, and helps to ensure a safe worksite for all.
With years of experience under our belt, Russell Group knows the value of ensuring expedited, reliable, inspections for our clients. Our team takes pride in creating technology that enhances the evaluation process, such as the state of the art VertiScan™ System. Developed to quickly detect and report multiple forms of degradation, including pitting, thermal fatigue cracking, under deposit corrosion, and hydrogen damage. VertiScan is a robotic system that scans up to five tubes at once at speeds up to 5m (15’)/min.
Extremely efficient, the VertiScan eliminates the need to scaffold boilers, and relays real time data of the scan on a color map that clearly outlines any degraded areas. For added clarity, indications found during the inspection are further checked with visual and ultrasonic techniques where tubes are accessible.
