Abstract

Claims (24)

1 . A connecting tee comprising:

a run defining first and second openings at first and second ends thereof;

a rise defining an rise opening; and

an inner surface defining a flow path through the rise and run, the flow path being interrupted by at least one raised portion on the inner surface.

2 . The connecting tee of claim 1 , further comprising first and second grooves defined in an outer surface of the connecting tee and configured to receive a coupling for connecting the first and second ends of the run to pipe components.

3 . The connecting tee of claim 2 , wherein the at least one raised portion on the inner surface is adjacent one of the grooves at the first and second ends of the rise.

4 . The connecting tee of claim 2 , further comprising a third groove defined in an outer surface of the tee, the groove being configured to receive a coupling for connecting the rise end to a pipe component.

5 . The connecting tee of claim 4 , the at least one raised portion comprising first and second raised portions on the inner surface aligned with the first and second grooves respectively and a third raised portion on the inner surface aligned with the third groove at the rise opening.

6 . The connecting tee of claim 2 wherein the outer surface at a transition from the rise to the run is arcuate around the entire periphery of the transition.

7 . A connecting tee comprising:

a run defining first and second openings at first and second ends thereof configured to connect to pipe components; and

a rise defining a third opening at a rise end thereof configured to connect to a pipe component, wherein an outer surface of the connecting tee at a transition from the rise to the run is arcuate around the entire periphery of the transition, and wherein the first and second openings at the first and second ends of the run and the third opening at the rise end are configured to connect to pipe components of the same size.

8 . The connecting tee of claim 7 wherein the outer surface of the connecting tee has first and second connecting grooves defined therein on the outer surface of the run and a third connecting groove on the outer surface of the rise.

9 . The connecting tee of claim 7 , an inner surface of the tee defining a flow path, wherein the inner surface has a plurality of raised portions defined thereon extending radially inwardly into the flow path.

10 . The connecting tee of claim 8 , wherein each of the plurality of raised portions is aligned with a connecting groove defined in the outer surface of the connecting tee.

11 . The connecting tee of claim 10 , wherein each raised portion spans the length of the groove with which it is aligned.

12 . A connecting tee comprising:

a run defining first and second openings at first and second ends thereof;

a rise extending from the run and defining a rise opening at an end thereof, the connecting tee having an outer surface, wherein the outer surface is arcuate at a transition between the rise and the run around the entire periphery of the transition;

first and second connecting grooves defined in the outer surface on the run and a third connecting groove in the outer surface on the rise; and

a plurality of radially inwardly extending raised portions defined on an inner surface of the connecting tee.

13 . The connecting tee of claim 12 , each raised portion being in aligned with one of the connecting grooves.

14 . The connecting tee of claim 13 , each of the first, second and third connecting grooves having a length, wherein the length of each is groove spanned by a raised portion on the inner surface of the connecting tee.

15 . The connecting tee of claim 13 , wherein the first and second connecting grooves are configured to connect the first and second ends to first and second pipe components, and wherein the third groove is configured to connect the rise to a third pipe component, the first, second and third pipe components being the same size.
