English: Title: Experts at Bureau of Standards study effect of corrosive soils on specimens of pipe. Washington, D.C., Aug. 8. Of interest to home builders the country over is the study being made by experts at the National Bureau of Standards of the effect of corrosive soils on pipes and protective materials. Samples of pipe which have been buried for four years in fifteen soils differing widely in their characteristics, are being tested. Included are several varieties of ferrous materials as well as copper, brass, and bronze. Soldered and brazed joints, protective materials, and pipe made of a composition of cement and asbestos are also represented. Walter Johnson, of the Bureau, is pictured removing graphitic corrosion from cast iron with an air-driven tool. The corrosion products are too hard to be removed with a brush or by chemical treatment, 8/8/38
