A THULIUM 170 NUCLEAR GAUGE FOR MEASURING SUPERHEATER TUBE WALL-THICKNESS IN A MARINE BOILER,

reportActive / Technical Report | Accession Number: AD0615050 | Need Help?

Abstract:

The nuclear gauge consists of a radioisotope which can be applied to the exterior of superheater tubes, and a geiger counter tube which can be inserted into the boiler tubes from the header. A sectional drawing of the arrangement is shown. The principle of the nuclear gauge is based on the absorption of radiation by the steel tube wall the thicker the tube, the lower the count, and the more wastage, the higher the count.
