The piping can be made of any one of the following materials: iron, steel, aluminum, copper, brass, Reinforced Cement Concrete (RCC). The material selected depends on the medium conveyed and the design temperature. At high temperature, creep is governing. At low temperature, brittleness is governing. Materials with food impact strength and malleability are used. Cross-country piping experience different environments. The valves, gages, instruments and appurtenances should be compatible with the piping. The cost of the piping is directly related to the material of construction.
