Abstract:

The inspections of cold water pipe lines were made in July 1961 and Feb 1962. Since only about 2 ft of pipe is exposed at each inspection, the condition of pipes reported may not apply over their entire lengths. The pipe wrapped in plastic tape and that wrapped in resin-impregnated glass cloth was rust free and still in excellent condition. However, the bare galvanized pipe, more recently installed, had lost its zinc plating and was covered with a light to medium rust. Furthermore, the bare dielectric-coupled galvanized pipe installed 25 months earlier was covered by a light loose rust and splotches of the zinc plating has suffered galvanic corrosion and is now black in color. The remaining pipes are continuing to deteriorate.
