Abstract

A method of assembling a tapping sleeve includes positioning an outlet band on a pipe element with an arcuate portion of the outlet band contacting an outer surface of the pipe element, the outlet band including a front end, a back end, a first side end, a second side end, a first bend line defined between the first side end and the second side end and extending from the front end to the back end, a second bend line defined between the first bend line and the second side end and extending from the front end to the back end, wherein the outlet band defines an arcuate portion between the first bend line and the second bend line, a first flange defined between the first side end and the first bend line, and a second flange defined between the second side end and the second bend line.

First claim

That which is claimed is:

1. A method of assembling a tapping sleeve, the method comprising:
positioning an outlet band on a pipe element with an arcuate portion of the outlet band contacting an outer surface of the pipe element, the outlet band comprising:
a tapping bore extending through the arcuate portion of the outlet band of the tapping sleeve;
a front end,
a back end,
a first side end,
a second side end,
a first bend line defined between the first side end and the second side end and extending from the front end to the back end,
a second bend line defined between the first bend line and the second side end and extending from the front end to the back end, wherein the outlet band defines the arcuate portion between the first bend line and the second bend line,
a first flange comprising a planar top surface defined between the first side end and the first bend line, and
a second flange comprising a planar top surface defined between the second side end and the second bend line; wherein the planar top surface of the first flange and the planar top surface of the second flange are angled relative to each other and are non-coplanar; and

adjustably attaching a cap band of the tapping sleeve to the outlet band and orienting the tapping bore of the outlet band by bending the first flange via a first connector and bending the second flange via a second connector at least until the planar top surface of the first flange and the planar top surface of the second flange are coplanar.

2. The method of claim 1 , wherein positioning the outlet band on the pipe element comprises placing a gasket surrounding the tapping bore defined in the outlet band against the pipe element and into sealing engagement with the pipe element.

3. The method of claim 1 , wherein the first flange and the second flange are angled with respect to a z-axis of the outlet band, and wherein the first flange and the second flange are non-coplanar when angled with respect to the z-axis.

4. The method of claim 3 , wherein adjustably attaching the cap band to the outlet band comprises securing the outlet band to the cap band around the pipe element.

5. The method of claim 1 , wherein adjustable attaching the cap band to the outlet band comprises positioning an arcuate portion of the cap band on the pipe element.

6. A method of manufacturing a tapping sleeve, the method comprising:
forming a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange comprising a planar top surface defined between the first side end and the first bend line;
forming a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange comprising a planar top surface defined between the second side end and the second bend line; wherein the planar top surface of the first flange and the planar top surface of the second flange are angled relative to each other and are non-coplanar; and
forming an arcuate portion defining a tapping bore in the outlet band between the first bend line and the second bend line.

7. The method of claim 6 , further comprising:
forming the outlet band from sheet metal prior to forming the first bend line, forming the second bend line, and forming the arcuate portion;
angling the first outlet flange with respect to a z-axis of the outlet band; and
angling the second outlet flange with respect to the z-axis of the outlet band, wherein the first outlet flange and the second outlet flange are non-coplanar after angling.

8. The method of claim 7 , wherein the first outlet flange and the second outlet flange are angled between about 0° and about 5° with respect to the z-axis of the outlet band.

9. The method of claim 6 , wherein forming the tapping bore between the first bend line and the second bend line comprising:
the tapping bore extending through the outlet band from a top surface of the outlet band to a bottom surface of the outlet band; and further comprising:
welding a neck to the outlet band, wherein the neck comprises a neck bore, wherein welding the neck comprises aligning the neck bore with the tapping bore.

10. The method of claim 9 , further comprising:
forming a gasket groove in the bottom surface of the outlet band around a perimeter of the tapping bore; and
positioning a gasket within the gasket groove.

11. The method of claim 6 , further comprising:
forming a first bend line in a planar cap band between a first side end and a second side end of the planar cap band, the first bend line extending from a front end to a back end of the planar cap band, a first cap flange defined between the first side end and the first bend line, the planar cap band formed from sheet metal;
forming a second bend line in the planar cap band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar cap band, a second cap flange defined between the second side end and the second bend line; and
forming an arcuate portion between the first bend line and the second bend line of the cap band.

12. The method of claim 11 , wherein forming the arcuate portion on the cap band comprises bending the cap band such that the arcuate portion is substantially similar to the arcuate portion of the outlet band.

13. The method of claim 11 , wherein the arcuate portion of the cap band and the arcuate portion of the outlet band are dimensioned to enable the cap band and the outlet band to be fitted on a pipe element.

14. The method of claim 11 , further comprising:
forming a first outlet securing bore in the first outlet flange;
forming a first cap securing bore in the first cap flange;
aligning the first outlet securing bore with the first cap securing bore; and
attaching the cap band and the outlet band together with a bolt positioned in the aligned first outlet securing bore and first cap securing bore.
