| Abstract: | The leakage of steam bend pipes under high temperature affects seriously chemical industries production. Through analysis effect of temperature on eddy current testing and its regularity , and the measures to eliminate the effect are put forward, the relationship between the flaws and characteristics of eddy current signals is analyzed and studied. Through practical testing, it shows that the eddy current testing can increase the testing speed, improve the sensitivity and test accurately. |
