Stock Lengths, 12 feet price depending upon the quality and size of the pipe and whether it is plain or polished. Fittings are sold by the piece, not by the pound, so that in taking off quantities the pipe would be scaled and the fittings counted the same as for wrought pipe. There is this difference in the case of brass and copper pipe, however - when the number of feet of the various sizes

of brass and copper pipe have been ascertained they should be multiplied, respectively by their weights per lineal foot, to reduce the quantities to pounds.

Note - When "Extra Heavy Iron Pipe Size" is ordered this list is followed unless order specifies a certain per cent heavy.

The weights per foot vary with the quality of pipe specified, which should be stated in the specifications. If not stated the weights can be found in catalogues of plumbing goods. To those who are skilled in working brass or copper pipe it takes no longer to install a piece of work than if the work were to be done with iron pipe. In fact, if anything it is easier and quicker to work brass or copper pipe than it is to work iron pipe. The weights per foot corresponding to the various sizes of brass and copper pipe can be found in Tables XII, XIII and XIV.
