Receiving inspections metals

Some of these parts, such as the threads on the pipe nipple, may have burrs on them, or shavings of metal that were not completely removed in the threading process done by the manufacturer. Pull these off, or grind them, or file them down. Inspect all parts as you receive them and finish working on them, and remove any such imperfections. 

Clay was added at the stoichiometric quantity needed for the sodium reactions and the ratios to MSW and DSS were 0.0235 g/g as-received MSW and 0.25 g/g dry DSS. During the run, considerable difficulty with the MSW feed system was encountered. Upon shutdown and inspection of the MSW, it was found that large metallic objects were present in the hopper and screw and were probably hindering the MSW feed to the combustor. 

Figure U.l Ultrasonic inspection techniques, (a) Contact pulse echo with a search unit combining a transmitter and receivers, (b) Contact through transmission. Transmitting search unit on top and receiving search unit on the bottom, (c) Immersion pulse echo with search unit (transmitter and receiver) and part inspected under water, (d) Immersion through transmission with both search units (transmitter and receiver) and part under water, (e) Immersion reflector plate. Same as (c) but each unit requires a reflector plate below the part being inspected.
