- 摘要:
- 目前,主要是把智能检测器放到管内,在输送介质的推动下,完成海底管道内、外腐蚀的在线检测,智能检测器的原理主要基于漏磁技术、超声波技术和涡流技术.本文介绍了以上三种检测技术的原理、检测器的结构、适应的介质以及优缺点.
At present,on-line testing method for underwater pipeline corrosion on both side of pipe wall is that a intelligent testing pig was put into the pipeline and pushed by fluid medium.The intelligent testing pig mainly based on the principle of magnetic leakage,ultrasonic & eddy.The paper introduced the principle,structure,advantages & defects for the 3 types testing technology.2001,2(2): 28-30 收稿日期：2000-12-29分类号：U178作者简介：毛宁林,通讯地址:山东省东营市泰山路446号,邮编:257073
