Abstract

Claims (23)

1. A fluid manifold for a high-pressure fracturing system, the fluid manifold comprising:

one or more spool sections;

a flow passage at least partially defined by the one or more spool sections that extends along a longitudinal axis;

a first flow altering assembly positioned along the flow passage, the first flow altering assembly including a diverter surface positioned to divert fluid flowing within the flow passage radially away from the longitudinal axis; and

a second flow altering assembly positioned along the flow passage and spaced from the first flow altering assembly along the longitudinal axis, the second flow altering assembly including:

an annular flange; and

a flow altering tube extending axially from the annular flange such that the annular flange and the flow altering tube define an annular cavity that extends radially between the flow altering tube and an inner wall of the flow passage and that extends axially along the flow altering tube to the annular flange,

wherein the flow altering tube comprises an inner surface extending axially between an open upstream end of the flow altering tube and an open downstream end of the flow altering tube such that the inner surface defines a through passage extending axially through the flow altering tube,

wherein at least one aperture having a first diameter extends radially through the flow altering tube to the through passage,

wherein the open upstream end of the flow altering tube defines an axial opening having a second diameter greater than the first diameter.

2. The fluid manifold of claim 1 , wherein the second flow altering assembly is upstream of the first flow altering assembly.

3. The fluid manifold of claim 1 , wherein the first flow altering assembly comprises:

a second annular flange; and

a plurality of supports extending between the second annular flange and the diverter surface, the plurality of supports being circumferentially spaced about the longitudinal axis so as to define a plurality of flow passages circumferentially between the plurality of supports.

4. The fluid manifold of claim 3 , wherein the diverter surface is spaced from the second annular flange along the longitudinal axis.

5. The fluid manifold of claim 4 , wherein the diverter surface comprises a convex curved surface.

6. The fluid manifold of claim 3 , wherein the plurality of supports extend radially from the second annular flange and the diverter surface.

7. The fluid manifold of claim 1 , wherein the open upstream end defines a leading edge of the flow altering tube and an outer surface of the flow altering tube defines a truncated cone-shaped profile between the leading edge and the open downstream end.

8. The fluid manifold of claim 7 , wherein the second flow altering assembly comprises a rear flow altering tube extending axially away from the annular flange on an opposite side of the annular flange from the flow altering tube, the rear flow altering tube diverging radially outward when moving axially away from the annular flange.

9. The fluid manifold of claim 1 , wherein:

a leading edge of the flow altering tube defines the open upstream end,

the leading edge includes a frustoconical surface, and

the frustoconical surface angles radially inward toward the longitudinal axis when moving axially away from the leading edge.
