Abstract
A pipe tee that has been modified to permit a second standard pipe tee to fit within it is described. The resultant 4-way combination fitting permits the angle of the respective annular appendages of the tees to be adjusted relative to each other.
Claims20
A modified pipe tee comprising:
- A longitudinally-extending base portion, the base portion having an arcuate interior surface that extends circumferentially around a longitudinal center axis and an exterior surface;
- and
- an annular appendage, the annular appendage having an appendage interior surface, an appendage exterior surface, and an appendage inside diameter and an appendage outside diameter, the annular appendage extending radially outwardly from the base portion exterior surface;
- wherein the base portion further defined by (i) a longitudinally-extending first cutout having a circumferential width of less than 3.14 radians and spaced apart first and second longitudinal edges, the first cutout being located generally opposite the annular appendage, and (ii) a circumferentially-extending second cutout extending from the first longitudinal edge to a location proximate the intersection of the base portion with the annular appendage, the second cutout having a width substantially parallel to the longitudinal axis and equal or greater than the appendage outside diameter.

A method of making a modified pipe tee, the method comprising:
- providing a standard pip tee, the standard pipe tee including (a) an annular base portion having a longitudinal center axis, an inside and an outside diameter with corresponding exterior and interior surfaces and, an annular appendage extending radially from the base portion and including inside and outside diameter also including corresponding interior and exterior surfaces;
- removing a section of the annular base portion to create a longitudinally-extending first cutout having a circumferential width of less than 3.14 radians and spaced apart first and second longitudinal edges, the first cutout being located generally opposite the annular appendage;
- and
- removing another section of the annular base portion to create a circumferentially-extending second cutout extending from the first longitudinal edge to a location proximate the intersection of the base portion with the annular appendage, the second cutout having a width substantially parallel to the longitudinal axis and equal or greater than the appendage outside diameter.
