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, 2-1/2-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.
