LATERAL FITTING INCLUDING OFFSET PARTING PLANE
First Claim
1. A fitting, comprising:
- a body;
a first flow passage extending through the body, the first flow passage defining a first longitudinal center axis; and
a second flow passage extending through the body to intersect the first flow passage, the second flow passage defining a second longitudinal center axis;
wherein the fitting is formed by a manufacturing process such that the body has a parting plane that is offset from, and parallel to, the first longitudinal center axis.

Abstract
A fitting is disclosed that includes a body; a first flow passage extending through the body; and a second flow passage formed in the body to intersect the first flow passage. The first and second flow passages define first and second longitudinal center axes, respectively. In an exemplary embodiment, the fitting forms a portion of a manifold assembly of a frac system. In one aspect, the fitting is formed by a manufacturing process such that the body has a parting plane that is offset from, and parallel to, the first longitudinal center axis. The fitting may have a first varying wall thickness defined between the first flow passage and the external surface; and a second varying wall thickness defined between the second flow passage and the external surface. In another aspect, a curved surface is formed in the body at the intersection between the first and second flow passages.

14. A method, comprising:
-
forging a fitting body, comprising compressing a material, using a first die having a first void volume and a second die having a second void volume that is greater than the first void volume, to form the fitting body so that the fitting body has a straight section and a branch section extending from the straight section; wherein the straight section has a center line; and wherein compressing the material to form the fitting body results in the fitting body having a parting plane that is associated with a relative position of the first die to the second die, the parting plane being offset by an offset distance from the center line of the straight section. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A fitting, comprising:
-
a body comprising a straight section and a branch section extending from the straight section; a first flow passage extending through the straight section of the body, the first flow passage defining a first longitudinal center axis; a second flow passage extending through the branch section of the body and intersecting the first flow passage, the second flow passage defining a second longitudinal center axis; an intersection formed in the interior of the body between the first and second flow passages, the intersection circumscribing the second flow passage; and a curved surface formed in the body at the intersection, at least a portion of the curved surface being co-planar with a plane in which both of the first and second longitudinal center axes extend; wherein the first and second longitudinal center axes intersect one another to form an acute angle; and wherein the portion of the curved surface that is co-planar with the plane in which both of the first and second longitudinal center axes extend is also located angularly between the first and second longitudinal center axes and within the acute angle. - View Dependent Claims (22, 23, 24, 25)
