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。
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.
