石化行业普遍使用直径数十米的钢制储罐储存石油、天然气和其他化工原料,在腐蚀、应力等环境作用下,储罐底板在长期服役后会出现腐蚀缺陷,对这些缺陷进行检测是保证储罐安全运行和视情维护的重要依据。本文介绍了基于虚拟仪器技术的储罐底板缺陷漏磁检测器,具体包括机械扫查装置、传感器模块、数据采集与传输模块、数据分析处理软件等。实验研究和现场应用证明,该检测器能实现对储罐底板的快速普查、缺陷的准确定位及量化,具有较高的检测灵敏度和可靠性。
Steel tanks with diameters of tens of meters are used to store oil,gas and other chemical materials in the petroleum industry.Tank floors will have corrosion defects under corrosion and stress environment after long-time service.Detection of these defects is critical for tank s safe operation and maintenance.This paper introduces a defects inspection system for tank floors based on virtual instrument technique.The inspection system includes mechanical scanning module,sensors,data acquisition and transmissio...
