A New NDT Technology for Precise Measurement of Tubes: The Inner Rotating Ultrasonic Inspection System

摘要: 在管子管束的在役检验和检修中，通常采用的电磁方法对缺陷及壁厚减薄不能进行精确定量。介绍了内置旋转式管子及管束超声波检测技术，可对管子内部缺陷及内外壁减薄进行全面检测。定量精度与普通超声波检测一致，满足检测及检修的要求，提高了热交换器管子及管束检测的准确性和可靠性。

Abstract: In the inspection of tubes in service, the most common method is the electromagnetic method, which however can not measure the defect and corrosion precisely. This paper introduced a new nondestructive testing (NDT) technology: the inner rotating ultrasonic inspection system(IRIS). Using this new technology, we can detect the inner defect and internal or external corrosion omni directionally, which its precision being almost the same as common ultrasonic test method. The proposed method can satisfy the requirement of inspection and overhauling. It also enhances the accuracy and reliability in the inspection of heat exchanger tubes.
