<p>A method of monitoring thinning of pipe walls (74) in a piping system including selecting locations (82, 84, 86, 90, 92, 94, 98) to be monitored, normally those pipes particularly susceptible to thinning from erosion/corrosion, boring holes in the outer surfaces of the pipes at the selected locations to depths greater than the thickness at which the pipes will rupture to leave predetermined residual wall thicknesses between the ends of the holes and the inner surfaces of the pipewalls, inserting tracer materials in the holes to be released in the pipes when pipe wall thinning exceeds the residual wall thicknesses of the holes, monitoring (114) fluid flow through the piping system to sense the presence of tracer materials in the fluid, and determining the location of the hole from which a sensed tracer material was released to permit pipe wall thinning to be determined prior to pipe rupture allowing repair or replacement during scheduled downtime of the piping system.</p> |
