The use of lead in the chemical and metallurgical operations at Trail, B.C. is described. A wide variety of corrosive environments are encountered, including phosphoric and sulphuric acids, sulphur dioxide, fluorides, and ammonium sulphate. It is found that except in the presence of fluorine compounds, 6% antimonial lead is more resistant to corrosion than is soft lead. The mechanical properties of lead are reviewed with particular reference to its high specific gravity, low mechanical strength, creep and fatigue properties. Principles of plant design to give adequate support, to provide for thermal expansion and contraction, and to minimize the effects of creep and fatigue are enunciated, and illustrated by proven designs that have given long periods of satisfactory service.
