APPARATUS FOR SEVERING AND COUPLING A PIPE

摘要

This apparatus provides a two-part rotatable housing which is mounted about a continuous gas or other pipeline for the purpose of cutting a section from the pipeline and coupling the separated parts together. The upper portion of the housing includes a built-in cutter assembly having a cutter advancing mechanism and the lower housing portion includes a cup for receiving the severed pipe section. The housing portions are separated by seals which facilitate rotation of the housing about the pipe during the cutting process. The seals prevent leakage from the pipeline and, in addition, electrically isolate the separated parts of the pipe.
