Gas diversion device and method for pipe repair therewith
First Claim
1. A gas diversion device comprising:
- a compression coupling having a first gasket disposed therein;
a first straight pipe section having a first open end and a second open end, the first open end being coupled to the compression coupling;
a Y-pipe having a first Y-pipe portion including a first Y-pipe open end and a second Y-pipe open end, the first Y-pipe open end being coupled to the second open end of the first straight pipe section, the Y-pipe further including a second Y-pipe portion having a second Y-pipe portion open end;
an electrically conductive pipe having a first end coupled to the second Y-pipe portion open end;
a slip to thread male adaptor coupled to the second Y-pipe open end, the slip to thread adaptor having a first threaded portion; and
a threaded cap threadably coupled to the first threaded portion and having a first hole therethrough;
wherein the compression coupling is adapted to be placed over an open end of a gas pipe service riser and wherein the first straight pipe section is adapted to receive a portion of the gas pipe service riser therein; and
wherein the threaded cap is adapted to receive an expansion plug tool through the first hole and wherein the first Y-pipe portion and the first straight pipe portion are adapted to slideably receive a portion of the expansion plug tool therein, the expansion plug tool further including an expansion plug coupled thereto to facilitate positioning of the expansion plug within the open end of the gas pipe service riser.

Abstract
A gas diversion device includes a compression coupling having a gasket disposed therein, and a first straight pipe section coupled to the compression coupling. The device further includes a Y-pipe coupled to the first straight pipe section and an electrically conductive pipe. The device further includes a threaded cap having a hole therethrough. The compression coupling is placed over an open end of a broken gas pipe service riser and the first straight pipe section receives a portion of the gas pipe service riser therein. The threaded cap receives an expansion plug tool through the first hole, and the Y-pipe and the first straight pipe slideably receive a portion of the expansion plug tool therein. The expansion plug tool further includes an expansion plug coupled thereto to facilitate positioning of the expansion plug within the open end of the gas pipe service riser.

7. A method for diverting gas from a broken gas pipe service riser using a gas diversion device, the gas diversion device having:
-
a compression coupling; a first straight pipe section having a first open end and a second open end, the first open end being coupled to the compression coupling; a Y-pipe having a first Y-pipe portion including a first Y-pipe open end and a second Y-pipe open end, the first Y-pipe open end being coupled to the second open end of the first straight pipe section, the Y-pipe further including a second Y-pipe portion having a second Y-pipe portion open end; an electrically conductive pipe having a first end coupled to the second Y-pipe portion open end; a slip to thread male adaptor coupled to the second Y-pipe open end, the slip to thread adaptor having a first threaded portion; and a threaded cap threadably coupled to the first threaded portion and having a first hole therethrough; the method comprising; selecting a first gasket having an inner diameter corresponding to an outer diameter of the broken gas pipe service riser; disposing the first gasket within the compression ring; placing the compression coupling over an open end of the broken gas pipe service riser such that the open end of the broken gas pipe service riser passes through the first gasket and the first pipe section receives a portion of the gas pipe service riser therein; sliding a portion of an expansion plug tool having an expansion plug attached thereto through the first hole, the first Y-pipe portion and the first straight pipe section; positioning the expansion plug within the open end of the gas pipe service riser; and detaching the expansion plug from the expansion plug tool. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A gas diversion device comprising:
-
an elongated body having an upper end and a lower end, the body defining an enclosed longitudinal passageway disposed along a longitudinal axis between the upper end and the lower end; the body further having an upper portion proximate to the upper end and a lower portion proximate to the lower end; the upper portion including a bifurcated section defining a first path and a second path, the first path constituting a portion of the longitudinal passageway and the second path originating from the longitudinal passageway and extending from the side of the body at an angle to the longitudinal axis; the lower portion being at least partially formed of a transparent material such that the interior of the longitudinal passageway is visible through the body from the exterior of the body; a first partial closure removably mountable on the upper end of the body, the first partial closure defining, when mounted on the upper end of the body, a first hole therethrough generally aligned with the longitudinal axis and having a cross-sectional area that is smaller than the cross-sectional area of the longitudinal passageway at the upper end of the body; a second partial closure mounted on the lower end of the body, the second partial closure defining a second hole therethrough generally aligned with the longitudinal axis and having a cross-sectional area that is smaller than the cross-sectional area of the longitudinal passageway at the lower end of the body; and an electrically conductive pipe having a first end coupled to the bifurcated section and defining an enclosed passageway disposed along the second path extending away from the body, the enclosed passageway being in fluid communication with the longitudinal passageway of the body. - View Dependent Claims (15, 16, 17, 18, 19, 20)
