Abstract
A method of manufacturing a flow block for use as a T-Block, tree block, manifold block or valve block, the method including: machining a main bore in a body; forming an opening in the body in a side wall of the main bore; providing an insert including a first bore intersecting with a second bore and being in fluid communication with each other; forming a substantially curved surface on at least part of the intersection between the first bore and the second bore; and inserting the insert into the opening, such that the first bore is substantially aligned with the main bore in order to provide a fluid flow path between the main bore and the second bore.
Claims16
A tubing hanger to support a completion tubing, including:
- a body including an exterior, a main bore, and a side bore extending between the main bore and the exterior;
- and
- an insert insertable from the exterior through the side bore and including a first bore and a second bore, the first bore being alignable and concentric with the main bore, the second bore intersecting the first bore at an intersection;
- wherein the intersection defines an inside corner and an outside corner of a fluid flow path;
- and
- wherein a substantially curved surface is positioned at one or more of the inside and outside corners.
A tubing hanger assembly to support a completion tubing, including:
- a body including an exterior, a main bore, and an opening in the body extending between the main bore and the exterior;
- and
- a preformed insert including a first bore intersecting with a second bore at an intersection for fluid communication between the first bore and the second bore;
- wherein the insert is configured for insertion from the exterior through the opening in the body such that the first bore is aligned and concentric with the main bore and the second bore intersects the first bore and is aligned with the opening to establish fluid communication between the main bore and the opening through the insert;
- and
- wherein the insert includes a substantially curved inner surface on at least a part of the intersection between the first bore and the second bore.
