Intelligent non-destructive testing
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.
