摘要
针对石化行业中在高温工作状态下的管道测厚问题,本文研究了超声波高温管道测厚方法中的一些影响因素,并实现了一套高温管道超声波测厚的仿真系统。实验中讨论了不同厚度、不同材料、不同噪声水平以及不同温度对超声波管道测厚结果的影响。此外,比较了不同测厚方法对管道厚度测量的影响。实验结果表明,该系统能够较好的模拟高温超声波测厚系统,能够实现高温管道厚度的测量。
Aiming at the problem of pipe thickness measurement under high temperature in the petrochemical industry,this paper investigates factors affecting high temperature pipe thickness measurements based on ultrasonic spectrum,and develops an ultrasonic thickness measurement simulation system.In the simulation experiment,the influence of different thickness,different materials,different noise levels and different temperatures on the measurement results are discussed.In addition,the influence of different thickness measurement methods on the measurement of pipe thickness is compared.The experiment results show that the system can simulate the high temperature ultrasonic thickness measuring system and measure the high temperature pipe thickness.
