摘要
为预测炉管的剩余寿命,研究高温炉管炉管壁和结焦厚度的在线检测技术,在单探头γ射线数字化扫描自动检测技术（GSDM-S）的基础上,开发基于GSDM-S的检测系统,并进行检测系统测试试验,以测试GSDM-S检测系统的精度。结果表明：用GSDM-S检测系统可在线检测炉管管壁和结焦厚度,检测误差好于±0.5 mm,满足GSDM-S检测系统装置设计要求;用基于GSDM-S的技术测得的壁厚结果与用超声方法得到的结果一致。
For the sake of forecasting and evaluating residual life of furnace tube and developing an on-line detection technology of tube wall and coking thickness of high temperature furnace tube,a GSDM-S measurement system was developed based on the GSDM-S measurement technique. Tube wall measurement experiments were carried out with the GSDM-S system. A measurement result comparison was made between the GSDM-S based technology and the supersonic method. The result shows the GSDM-S detection system can be applied to confirm the wall thickness of the furnace tube,the deviation is better than ±0. 5 mm and meets the design requirements of the GSDM-S detection system device,and that the wall thickness measurement results obtained by using the GSDM-S based technology are in agreement with those obtained by using the supersonic method.
