本文讨论了超声波导波对钢板下表面腐蚀区域快速定位及连续测厚法准确测定其最小壁厚的检测方法,并通过试验测试验证了上述检测方法的准确性和有效性,从而为不能进入内部的压力容器、内表面被覆盖层或构件覆盖的压力容器及大型原油储罐底板下表面的腐蚀检测提供了一种有效的检测方法。
This article discusses the ultrasonic guided wave on the corrosion of the lower surface of the steel plate rapid positioning and continuous thickness measurement method for the determination of the minimum wall thickness of the test method and tested by the test to verify the accuracy and effectiveness of the above detection methods, Of the pressure vessel, the inner surface of the pressure vessel covered by coating or member and the bottom surface of the large crude oil tank corrosion detection provides an effective detection method.
