One of the earliest NDT applications for laser-based profilometry systems was for the inspection of marine boiler tubes. Under funding from the U.S. Navy", several systems were developed that were capable of rapidly and accurately mapping the inside surface of 25 mm and 50 mm diameter boiler tubing. Features such as internal pitting and corrosion can be located and quantitatively assessed using computer-graphic analysis. The system employs an...

In addition to their automotive use, PAO oils also find appfication in industrial and aircraft hydraufic fluids, gear oils, compressors, and environmentally sensitive appfications. They are also used in multipurpose greases for army, navy, nuclear, and industrial appfications. Expanding use has led to a growth rate of PAO production from 1985 to 1990 of 19% per year (28).

The large candles used by the U.S. Navy have been produced ia the United States by three companies. Mine Safety AppHances Company, Puritan-Beimett Corporation, and Scott Aviation. These sell for 50— 60. Production is less than 10,000/yr. Smaller candles incorporated ia breathing apparatus are produced by equipment suppHers. Production quantities are tied to the number of complete units and the candles are a small percentage of the total price. Production for aircraft oxygen supply during a decompression incident is about 50,000 units per year. In the United States, Puritan-Beimett and Scott Aviation are the primary suppHers as is Draeger in Germany.
