Abstract:
1. A system for non-destructively examining degradation of an ammonia refrigeration line, wherein such line has a metal layer and a composite insulation layer, the system comprising: a collar sized and shaped to be mounted on an outer surface of the ammonia refrigeration line; a radiography device movably coupled to the collar, the radiography device including a source of radiography signals positioned to direct radiography signals through at least a portion of the metal layer and the composite insulation layer and a detector to detect the radiography signals; and a computer connected to the detector to display graphical or numerical data of the ammonia refrigeration line generated from the detected radiography signals, wherein the radiography device is coupled to the collar in a manner so that it is movable about at least one of: 1) around the circumference of the ammonia refrigeration line; 2) along the axis of the ammonia refrigeration line; and 3) along a path perpendicular to the axis of the ammonia refrigeration line.
