The U.S. Bureau of Mines (USBM) was the primary United States Government agency conducting scientific research and disseminating information on the extraction, processing, use, and conservation of mineral resources.
Founded on May 16, 1910, through the Organic Act (Public Law 179), USBM's missions ...
A tester developed by the U.S. Bureau of Mines for detecting and controlling corrosion in steam-condensate-return lines of large heating plants. This tester determines types and rates of corrosion and can distinguish among various possible causes. It is assembled from ordinary black iron pipe nipples and couplings, the linings are easily machined, and the corroded linings can be analyzed quickly in any laboratory.
