Process for boring bolt holes in mating coupling flanges

Abstract

A method of boring a plurality of aligned, mating bolt holes in a pair of separated coupling flanges comprising the steps of: a) providing a template with pre-formed holes matching a desired location for bolt holes in the pair of coupling flanges; b) securing the template to a first of the pair of coupling flanges; c) attaching a boring tool to the template in alignment with one of the bolt holes; d) re-boring one of the bolt holes in the first coupling flange and repeating steps c) and d) for each remaining bolt hole individually in succession; e) removing the boring tool and template from the first coupling flange; f) relocating the template on the second of the pair of coupling flanges; and g) repeating steps b) through e) for the bolt holes in the second coupling flange.
