Abstract: 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.

Key words: high temperature furnace tube, γ-ray digital scanning technology-single (GSDM-S), corrosion, coking, wall thickness
