HotScan: Ultrasonic system for inspection and structural health of high temperature superheated steam pipes
Long range ultrasonic system for continuous in-service inspection and structural health of high temperature superheated steam pipes in power generation plant with 100 per cent coverage.
High temperatures and pressures in superheated steam pipes in power plants can lead to the formation of flaws and defects due to material degradation mechanisms such as corrosion, creep and fatigue over time.
The overall aim of the Hotscan project was to develop high temperature ultrasonic guided wave transducers to enable inspection and monitoring to be carried out on high temperature pipe work, and as a result increase the safety and efficiency of power plants and oil refineries. The specific objectives of the research were:
- To improve the current transducers to enable UGW testing at temperatures up to 250C.
- To develop transducers that can operate at temperatures up to 580C.
- To develop a high temperature collar array to enable UGW testing on pipes in laboratory and field conditions.
- To investigate defect detection capability of the developed transducers at elevated temperatures in laboratory conditions, and deploy the developed transducers and the collar array in real life conditions.
The main objectives of this research have been achieved by developing UGW transducers that can withstand elevated temperatures. However, further work is still required for these transducers to be used in commercial UGW systems, including assessing the feasibility of defect detection using LN transducers at up to 580°C, and testing the transducer collar array in a power plant at up to 250°C.
The research has achieved significant advances towards enabling UGW inspection and condition monitoring of high temperature pipe work by developing transducers that can operate at elevated temperatures.
