Abstract

A mechanical branch outlet includes: a housing defining: an outer surface; an inner surface; and an outlet bore extending between the outer surface and the inner surface; an insert defining: a wall; an axis; a rim extending radially outward from the wall with respect to the axis, the rim being a flange; a first end extending from the rim in a first axial direction aligned with the axis; and a second end extending from the rim in a second axial direction opposite from the first axial direction; the first end received fully within the outlet bore of the housing; the outlet bore of the housing configured to slidably receive the second end and retain the first end, an outer diameter of the rim being greater than an outer diameter of the second end.

First claim

That which is claimed is:

1. A mechanical branch outlet comprising:
a housing defining:
an outer surface;
an inner surface; and
an outlet bore extending between the outer surface and the inner surface; and

an insert configured to be formed from a tubular member defining a first end and a second end, the tubular member defining a constant wall thickness from the first end to the second end, the insert defining:
a wall defining a thickness equal to the wall thickness of the tubular member;
an axis;
a rim extending radially outward from the wall with respect to the axis, the rim being a flange;
a first end extending from the rim in a first axial direction aligned with the axis; and
a second end extending from the rim in a second axial direction opposite from the first axial direction; the first end received fully within the outlet bore of the housing; the outlet bore of the housing configured to slidably receive the second end and retain the first end, an outer diameter of the rim being greater than an outer diameter of the second end.

2. The mechanical branch outlet of claim 1 , further comprising a gasket defining an inner bore defining an inner diameter, the inner diameter sized to receive the first end of the insert.

3. The mechanical branch outlet of claim 1 , further comprising a gasket comprising a first sealing leg and a second sealing leg, the first sealing leg positioned to contact a pipe when the housing is installed on the pipe and the second sealing leg contacting the insert.

4. The mechanical branch outlet of claim 3 , wherein the gasket defines a pocket between the first sealing leg and the second sealing leg, the pocket facing radially inward with respect to the axis of the insert.

5. The mechanical branch outlet of claim 1 , further comprising a gasket, the rim of the insert positioned between the housing and the gasket.

6. The mechanical branch outlet of claim 1 , wherein the rim is integral with a material of the insert.

7. The mechanical branch outlet of claim 1 , wherein a thickness of material forming the rim is equal to a wall thickness of the wall of the insert.

8. The mechanical branch outlet of claim 7 , wherein a thickness of the rim is equal to the wall thickness of the wall of the insert.

9. The mechanical branch outlet of claim 1 , wherein the outer diameter of the rim is greater than a maximum outer diameter of each of the first end and the second end of the insert.

10. The mechanical branch outlet of claim 1 , wherein the insert is formed from copper.

11. The mechanical branch outlet of claim 1 , wherein the second end is folded back over itself and extends towards the first end in an axial direction with respect to the axis of the insert.

12. A method for assembling the mechanical branch outlet of claim 1 to a pipe, the method comprising connecting a piping system element to the insert with a crimped joint.

13. A method for assembling the mechanical branch outlet of claim 1 to a pipe, the method comprising:
assembling a gasket to the pipe between the housing and the pipe by contacting a first sealing leg of the gasket with an outer surface of the pipe; and
contacting a second sealing leg of the gasket with an outer surface of the insert of the mechanical branch outlet.

14. A pipe system comprising:
a mechanical branch outlet comprising:
a housing defining:
an outer surface;
an inner surface; and
an outlet bore extending between the outer surface and the inner surface;

an insert defining:
a wall;
an axis;
a rim extending radially outward from the wall with respect to the axis, the rim being a flange;
a first end extending from the rim in a first axial direction aligned with the axis; and
a second end extending from the rim in a second axial direction opposite from the first axial direction; the first end received fully within the outlet bore of the housing; the outlet bore of the housing configured to slidably receive the second end and retain the first end, an outer diameter of the rim being greater than an outer diameter of the second end; and

a gasket received within the housing and about the insert, the gasket comprising a first sealing leg in contact with an outer surface of the pipe and a second sealing leg in contact with an outer surface of the insert, the gasket defining a pocket between the first sealing leg and the second sealing leg, the pocket configured to receive a fluid contained within the pipe system; and

a pipe, the pipe defining a transverse bore in an outer wall of the pipe, the transverse bore sized to receive the first end of the insert, the mechanical branch outlet being assembled to the pipe.

15. The pipe system of claim 14 , wherein the insert extends from the pipe at an angle to a longitudinal axis of the pipe that is equal to 90 degrees.

16. The pipe system of claim 14 , further comprising a gasket positioned between the housing and the pipe, a curvature of a lower surface of the gasket matches a curvature of the pipe.

17. The pipe system of claim 14 , wherein the housing of the mechanical branch outlet is isolated from a fluid path defined through the pipe and through the insert when the pipe system is in an assembled state.

18. The pipe system of claim 14 , wherein the pocket faces radially inward with respect to the axis of the insert.

19. The pipe system of claim 14 , wherein the insert extends through the outlet bore of the housing, the pipe system further comprising a piping system element, the piping system element secured to the insert with a crimped joint.

20. A method for manufacturing a mechanical branch outlet, the method comprising:
forming a housing defining:
an outer surface;
an inner surface; and
an outlet bore extending between the outer surface and the inner surface; and

forming an insert from a tubular member defining a first end and a second end, the tubular member defining a constant wall thickness from the first end to the second end, the insert defining:
a wall defining a thickness equal to the wall thickness of the tubular member;
an axis;
a rim extending radially outward from the wall with respect to the axis, the rim being a flange;
a first end extending from the rim in a first axial direction aligned with the axis; and
a second end extending from the rim in a second axial direction opposite from the first axial direction; the first end received fully within the outlet bore of the housing; the outlet bore of the housing configured to slidably receive the second end and retain the first end, an outer diameter of the rim being greater than an outer diameter of the second end.

21. The method of claim 20 , wherein forming the insert comprises mechanically deforming material forming the rim of the insert.

22. The method of claim 20 , wherein forming the insert comprises heating at least a portion of the tubular member from which the rim is formed.

23. The method of claim 20 , wherein forming the insert comprises:
folding the second end of the tubular member back over itself; and
extends the second end towards the first end in an axial direction with respect to the axis of the insert.
