EIS Board

提出了一种基于电阻抗谱（EIS）的绝热层腐蚀缺陷检测系统。它解决了在热绝缘下检测腐蚀的问题，特别是覆盖有厚的、重的隔热层并被外部金属覆层包围的情况。进入的水可以收集并被捕获，加速腐蚀过程，特别是在高温下。大多数当前的SoA要求通常需要去除底层绝缘，昂贵，缓慢，高度局部化，通常是劳动密集型的，并且经常涉及关闭操作。我们的方法- ·不需要拆除隔热层·可以立即扫描很长长度的隔热管道的整个表面·安装速度快且相对便宜·可以检测突然的灾难性泄漏和破坏·在大型密集管网中提供完整的24小时实时腐蚀监测系统。

A novel system for the detection of corrosion defects under thermal insulation based on Electrical Impedance Spectroscopy (EIS). It addresses the problem of detection of corrosion under thermal insulation especially that covered with thick, heavy lagging and surrounded with an outer metal cladding. Water which enters can collect and be trapped accelerating the corrosion process especially at high temperatures. Most current SoA requires often requires the removal of the underlying insulation, are expensive, slow, highly localised, are usually labour intensive, and often involve shutting down operations. Our approach - •Does not require the removal of thermal insulation •Can scan the entire surface of very long lengths of insulated pipeline instantaneously •Is quick and relatively inexpensive to install •Can detect both sudden catastrophic leaks and breaches •Provides a complete real-time 24 hour corrosion monitoring system in large, dense pipeline networks.
