Improving quality in steel tubing for

nuclear power stations STEEL tubing is an essential component in the infrastructure of nuclear power stations. These tubes are used in various critical applications, including the transportation of coolant, steam and other fluids necessary for the reactor’s safe operation. In cooling systems, tubing is used to circulate coolant to dissipate heat generated during nuclear fission, preventing the reactor from overheating. Tubes are also used to transport steam from the reactor to turbines, converting thermal energy into electrical energy, and are also used to house and protect sensitive instrumentation that monitors reactor conditions, ensuring accurate and reliable data collection. Given the extreme conditions within a nuclear reactor, the quality and reliability of these tubes are paramount. Within a nuclear power station, steel tubing must be able to withstand high temperatures, pressure and radiation. The tubes are often exposed to corrosive environments, especially when used in cooling systems that utilise seawater. Therefore, the materials used must be highly resistant to corrosion and capable of maintaining structural integrity under stress. Stainless steel, particularly austenitic stainless steel, is commonly used due to its excellent corrosion resistance and ability to withstand high temperatures. Grades such as 304L and 316L are frequently employed within nuclear applications. These materials ensure that the tubes can perform reliably over long periods, reducing the risk of failures that could lead to catastrophic consequences. To meet the stringent quality requirements of nuclear power stations, manufacturers rely on advanced measurement and control systems in the production of steel tubing, and as a global leader in non-contact measuring technologies, Zumbach Electronic offers a range of products including the ODAC ® and USYS that play a crucial role in this process. The high performing ODAC ® laser measuring heads utilise the very latest laser technology to measure the diameter and ovality of steel tubes with exceptionally high accuracy and reliability. These non-contact measuring devices can detect even the smallest deviations from specified dimensions, ensuring that each tube meets the required standard, and can be used in almost every harsh environment. ODAC ® ’s are exceptionally durable and offer virtually maintenance-free operation even where there is the presence of oil, steam and dust in the atmosphere. The high scan rates and accuracy of ODAC ® systems make them ideal for in-line measurements during production, allowing for real-time quality control. The USYS processor complements the ODAC ® by providing comprehensive data acquisition, processing and display capabilities, as well as linking to higher level systems. USYS collects data from the ODAC ® measuring heads (as well as other measuring devices offered by Zumbach Electronic), processing it to provide reports and detailed insights into the manufacturing process. This real-time data allows tubing manufacturers to make immediate adjustments, improving both the quality and efficiency of the production.

The integration of Zumbach ODAC ® and USYS systems in the production of steel tubing offers: • Enhanced quality control: continuous monitoring and precise measurements ensure that each tube meets the highest quality, reducing the risk of defects. • Increased efficiency: real-time data processing and feedback enable manufacturers to optimise production processes, reducing waste and improving throughput. • Cost savings: by minimising defects and optimising production, tubing manufacturers can reduce costs associated with rework and material waste. • Compliance with standards: Zumbach systems help manufacturers comply with stringent industry standards, ensuring that the steel tubing manufactured for use in nuclear power stations is safe and reliable.
