Claims7
A one-piece seamless reducer comprising a single continuous sheet of material including:
- a) a first section including a first wall symmetrically surrounding and substantially parallel to a central axis, the first wall defining an outer diameter and an inner diameter,
- b) a second section including a second wall symmetrically surrounding and substantially parallel to the central axis, the second wall defining an outer diameter and an inner diameter, wherein the outer diameter of the first wall is greater than the outer diameter of the second wall and further wherein the inner diameter of the first wall is greater than the inner diameter of the second wall, and
- c) a tapered section including a tapered wall symmetrically surrounding the central axis, the tapered wall connected to and extending between the second section and the first section in a direction at an axis angle from about 25° to about 40° with respect to the central axis, wherein the first section, the second section and the tapered section define a one-piece seamless reducer.
