[Fig. 146] represents one form of a pipe cutter which is made to use by hand; cutters are also made for use by power, which are capable of cutting off pipes of immense size. In an engineer’s outfit of steam fitting tools 2 sets are advisable—one to cut pipe 1⁄8th inch to 1 inch, and the other to cut 1 to 2-inch pipe. Figs. [147], [148], represent different forms of pipe tongs—the former called “chain” tongs which will readily hold three-inch pipe. [Fig. 149] represents a steam fitter’s vise which will “take” say, 21⁄2-inch pipe down to 1⁄8th. [Fig. 150] shows a set of taps and dies for small bolts and nuts which is ordinarily to be found in a steam fitter’s outfit although used very generally by machinists and others. [Fig. 151] shows a pair of gas-pliers which are used by steam fitters in gas-pipe jobs. [Fig. 152] exhibits the old-fashioned alligator wrench.
In ice and refrigerating jobs of pipe fitting special tubes are used to assure a niceness of joints and fitting which is not called for in steam and water service.
