ABSTRACT:
A reusable template is disclosed herein for use in cutting pipe and other related applications in conjunction as a guide for an oxygen cutting torch. The template, as described in a preferred embodiment as a pipe template, has one or more contour ends so configured that after the branch pipe is cut it will fit flush against the external surface of a header pipe at the desired angle determined by the configuration of the contour end. The template is made of oxidation resistant material, with an alloy content sufficient to produce refractory oxides when heated by a flame, thus preventing the template from being cut by the oxygen cutting torch. The template is held in place over or on the workpiece or pipe by means well known in the art. The contour end or shape of the template is used as a guide for the nozzle of a standard oxygen cutting torch. Since the template is made of oxidation resistant material, the torch will cut the workpiece or pipe in the configuration of the contour of the template without destroying the template.
