American Society of Heating and Ventilating Engineers Guide, 1924-25 All reliable data on this subject indicate that the composition of the iron--i.e., the varying amount of carbon, phosphorous, manganese, sul phur, silicon, oxides, slag and copper usually found in wrought iron and soft steel--makes very little difference in the amount or character of corrosion under water, although under atmospheric exposure the influence of composition is sometimes quite marked. In practice, oxygen removal has been accomplished in two ways, namely; by de-aerating the water mechanically; and by fixing the free oxygen by chemical combination. Suitable apparatus is now being manufactured for this purpose. Size TABLE 89.

From National Tube Co.*s "Book of.Standards." ; 154 American Society of Heating and Ventilating Engineers Guide, 1924-25 WROUGHT IRON PIPE Wrought iron pipe is generally designated by the word genuine when the product referred to is that produced by the puddling process and its cost is from 30 to 60 per cent higher than steel pipe, depending upon its size. In the average heating, plumbing or power piping system the cost of pipe is about 10 to 20 per cent of the installation cost, with the remain- TABLE 90.
