Want to learn about the IRIS internal rotation detection system

Finally, I’ve found the information; here I share with everyone the product introduction materials represented by Tianjin Haoda Company. Visit the website http://www.haodapana.com.cn/. There is a link on the home page titled \"New Product Introduction\"; it contains detailed information about IRIS. It is said that only the China National Special Equipment Inspection and Testing Center and the Tianjin Special Equipment Inspection and Testing Center are interested in purchasing this new technology and equipment to launch new projects. . .

The website http://www.smle.cn/goods252.aspx provides information on the ultrasonic heat exchange tube inspection system, the IRIS 9000 system; those who are interested are encouraged to pay close attention to it. The following content is excerpted from the linked page for reference: *************************************** Non-destructive testing | Fault diagnosis -> Ultrasonic testing system IRIS -------------------------------------------------------------------------------- Ultrasonic heat exchanger tube testing system ------------------------------------------------------------------------------- IRIS testing services IRIS Testing Services was established in 1985 and is a leading provider of internal-rotation ultrasonic systems for measuring the wall thickness of heat exchanger tubes. For 22 years, we have been the first manufacturer and supplier of digital internal-rotation ultrasonic B- and C-type heat exchanger tube scanners, setting industry standards in this field. Experience, a strong sense of responsibility, and continuous innovation have made IRIS Detection Services the undisputed industry leader in IRIS technology. IRIS basic system, IRIS 9000 printer, water filters/pressure regulators/probe tool sets, probe decoders/motor drives (optional), calibration test tubes. A brief description of the IRIS ultrasonic principle: The IRIS 9000 utilizes ultrasonic immersion pulse-echo technology; the ultrasonic sensor is installed in the testing head and is designed to extend into the heat exchange tube and remain at its center. Ultrasonic pulses are sent along paths parallel to the axis of the tube, where they are reflected by 45-degree mirrors within the tube walls, resulting in reflected pulses that are directed toward both the inner and outer walls. These reflected pulses return to the sensor along the same paths. The time difference between the first echoes reflected from the inner and outer surfaces of the tube indicates the thickness of the tube wall. As the rotary mirror turns, the ultrasonic beam moves around the pipe; each successive pulse creates a pattern on the IRIS 9000 screen that resembles a horizontal scan line. One full rotation yields 192 readings, with 2400 rotations per minute. When the probe moves along the pipe at an optimal inspection speed of 2.54 meters per minute, the ultrasonic pulses trace out a continuous spiral path that covers the entire pipe wall. The inspection results for finned heat exchangers and plastic tube bundle heat exchange tubes are also highly reliable. Driven by a spirit of leadership in research and innovation, the IRIS 9000 combines edge-ultrasonic imaging technology with reliability in field use, along with unparalleled customer support. It features excellent performance, self-calibration capabilities, and high precision of +/-0.05 mm (0.002”). The maximum pipe length is 30 m (99), while the inner diameter of the pipes ranges from 8.6 mm (0.34”) to 82.6 mm (3.25”). On-site calibration and text encoding of inspection data are available. The probe is driven forward by a motor, and the device has a menu-based operating system. It supports both imperial and metric units for measurements. It is designed for special applications without relying on a PC. This technology provides reliable inspections with good repeatability. Compared to other inspection methods, it is a variable-based technique that does not produce unreliable estimates or fixed initial wall thickness percentages (which may be unknown!) ). Since the calibration of this instrument allows the determination of the speed of the material being tested, the results are independent of a specific reference sample or nominal wall thickness. Furthermore, this technology is not affected by the structure of the heat exchanger. The coverings, hardeners, tube sheets, fins, and their positions do not affect this ultrasonic technique. The IRIS 9000 graphical display of the tube wall cross-section facilitates the identification of the type and location of tube wall damage

This post deserves to sink to the bottom! No one has yet recognized the value of the IRIS system, at least not in our **. Let me ask: how should the wall thickness of the tube bundles in tubular heat exchangers and air coolers be evaluated? We can’t wait until it corrodes and perforates before replacing it; by then it will be too late. It is difficult to measure thickness during maintenance, and even more so online. This system is already being used very well abroad. During maintenance, it is very effective to use the IRIS system to inspect the minimum wall thickness of the tube bundle, its corrosion status, and the presence of any defects.

Reply to 4# qldch2306: Give it some support. Pre-inspection of domestic equipment has not yet developed; not enough attention is paid to it, and it will take some time!
