MSGW pipeline ultrasonic guided wave detector

Product Features The MSGW ultrasonic guided wave detection system is a long-distance and large-scale fast scanning technology suitable for detecting corrosion and crack defects on the inner and outer walls of in-service pipelines; The MSGW ultrasonic guided wave detection system achieves full cross-section coverage testing on pipelines with single point layout, unidirectional tens of meters or even hundreds of meters. In conjunction with conventional non-destructive testing technology, it achieves efficient and high-precision defect detection of large-scale pipelines; The MSGW ultrasonic guided wave detection system can not only realize rapid detection for conventional pipelines, but also perform efficient detection for pipelines in special occasions, such as crossing pipelines, high-temperature pipelines, overhead pipelines, oil platform riser networks, etc; The MSGW ultrasonic guided wave detection system can detect metal pipelines, tank bottom plates, tank wall panels, power line towers, bridge cables, and other structures.

UGPM Pipeline Structure Health Online Monitoring System

Product Features Select appropriate monitoring points and install monitoring transducers; Collect stable and representative signals and set them as reference signals; Regularly collect data using ultrasonic guided wave inspection systems or real-time online monitoring systems to obtain batch sampling signals; Analyze the collected data and perform difference analysis and trend analysis separately.

Distance circumferential scanning system in MRCS

technical parameter Product Features MRCS scans the circumferential direction of pipelines or plate planes to achieve B-scan visualization digital imaging; MRCS scans the pipeline circumference or plate plane to achieve circumferential positioning of pipeline corrosion; MRCS scans the pipeline circumference or plate plane to improve defect detection sensitivity and image resolution; MRCS scans the circumferential direction or plate plane of pipelines, making up for the limitations of long-distance ultrasonic guided wave detection, such as difficulty in signal interpretation and poor detection effect in the attachment area.

Railway Switch Broken Track Monitoring System

Product Features Actively excite and receive encoded ultrasonic guided waves of specific frequencies in the steel rail to avoid the influence of other interference signals Actively suppress non target frequency signals such as vibration noise and electromagnetic noise of the contact network to ensure robustness The excitation interval of the guided wave can be set at least 15 seconds, which can complete the structural safety state scanning of the rail in an extremely short time The workflow and damage identification are automatically completed by server scheduling algorithms, enabling unmanned operation While collecting guided wave monitoring signals, record multidimensional non damage parameter information such as switch status, train passing status, and environmental temperature and humidity data The system automatically tracks suspected damage signals and records their growth process. When the crack damage cross-section extends to 5% of the switch rail cross-section, a stable alarm can be output Adopting two modes, PE and PC, redundancy detection and increased sensitivity, reducing low false alarm rate while ensuring zero false alarm rate

Ultrasonic Guided Waves on Steel Pipe Poles of a Transmission Line of a State Grid Jiangsu Electric Power Company

Our company collaborated with a certain power company from State Grid Jiangsu to conduct guided wave testing on the corrosion of transmission line steel pipe poles in Jiangsu Province. A total of over 2000 transmission line steel pipe poles were tested, and some of them were found to have severe corrosion. Among them, a total of 1219 pieces were tested in 2018, which took 113 days. During the inspection process, it was found that there were 11 defects in the steel pipe poles of the transmission line, of which 9 were internal corrosion and 2 were external corrosion. In 2019, a total of 660 steel pipe rods were inspected, lasting 79 days. During the inspection process, 8 steel pipe rods were found to have defects, of which 5 were internal corrosion and 3 were external corrosion.

Ultrasonic guided wave inspection of overhead pipelines on an offshore platform of China National Offshore Chemical Corporation

In April 2016, entrusted by CNOOC Testing Company, ultrasonic guided wave testing was conducted on an important pipeline of a CNOOC South China Sea offshore platform. The testing cycle was one month, and more than 200 locations were completed. During this inspection process, corrosion was found in local pipelines.

Ultrasonic Guided Wave Detection of Embedded Depth of Expressway Columns in Hubei Province

In August 2016, a testing center of the Science Research Institute of the Ministry of Transport used our company's developed highway column burial depth detector to test the burial depth of multiple highway columns in Hubei Province. The testing cycle lasted for 4 months, and more than 20000 locations were completed. This technology does not damage the roadbed during detection, with fast detection speed and high detection accuracy.

Ultrasonic guided wave monitoring of a gathering and transportation pipeline in a certain oil field of PetroChina

In June 2017, there was a leakage phenomenon in the condensate gathering and transportation pipeline of a certain oil field of PetroChina. Our company was commissioned by a certain oil field to conduct regular ultrasonic guided wave monitoring of the condensate gathering and transportation pipeline with high-risk leakage. This time, 10 monitoring points were installed. Regularly collect and analyze ultrasonic guided wave monitoring data for condensate gathering and transportation pipelines every quarter, and the monitoring equipment is currently operating well.
