A System for High Speed Detection of Seamless Steel Pipe and Defect Recognition

In the high speed and automatic seamless pressure steel pipe detection system developed, two dimensional magnetic leakage measuring technology is adopted for the detection of various smaller defects, and dynamic ultrasonic thickness measuring technique is used to detect larger defects and to measure the wall thickness. By means of computer supervisory control technique, the compute process of monitoring and measurement, the analysis, computation as well as the storage of the defect signals, the recognition of types of defects, the markings and locations of the defects are displayed in graphs. Practical operations in 6 odd years show that the system is stable and reliable. Some useful data are given.
