Guide Vane Insert Layout for Erosion-Prone Cross-Drill Bores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flow manifolds in the oil and gas industry face significant erosion issues due to fluid flow, leading to increased size, weight, and cost, as well as potential damage to critical components, particularly at cross-drill intersections, which complicates system design and increases manufacturing costs.
Innovation Solution
The integration of guide vane inserts within flow bores of valve blocks, featuring vanes and a pig bar, which create a more uniform flow, reduce erosion rates, and act as sacrificial elements, thereby minimizing the need for long flow bores and additional corrosion-resistant alloy layers, resulting in a lighter, less complex, and cost-effective design.

Engineering Contradiction Analysis
1Object-affected harmful factors
If long straight flow bores or pipes are used to reduce erosion effects, then erosion resistance is improved, but footprint and overall size increase
Solution Approach 1:
The flow path is segmented into multiple sections with varying orientations (horizontal, vertical, angled) rather than using a single long straight bore. This segmentation allows the flow to change direction progressively, reducing erosion effects while maintaining a compact overall footprint.
Solution Approach 2:
The flow path transitions from two-dimensional horizontal flow to three-dimensional flow by incorporating vertical and angled sections. This dimensional change allows the flow to navigate through the valve block in a compact space while reducing erosion through directional changes.
2Object-affected harmful factors
If CRA layer with increased thickness is applied to flow bores to reduce erosion, then erosion resistance is improved, but manufacturing cost increases
Solution Approach 1:
The flow path is pre-configured with strategic bends and directional changes before the fluid enters critical areas. This preliminary action redirects high-velocity particles away from sensitive components and cross-drill intersections, reducing the need for thick CRA layers and associated manufacturing costs.
Solution Approach 2:
The flow path geometry acts as an intermediary mechanism that indirectly protects critical components by redirecting erosive flow patterns, rather than directly applying thick protective layers to all surfaces. This geometric mediation reduces material costs while maintaining protection.
3Object-affected harmful factors
If target tees are used to damp flow and reduce velocities, then erosion resistance is improved, but device complexity and weight increase
Solution Approach 1:
The flow damping function is merged into the existing valve block structure through integrated flow path design, rather than adding separate target tee components. The flow path geometry itself performs the damping function by creating controlled turbulence and velocity reduction zones within the compact valve body.
Solution Approach 2:
The flow path geometry serves multiple functions simultaneously: it directs flow from multiple sources, dampens velocity through strategic bends, protects critical components from erosion, and maintains structural integrity. This multi-functionality eliminates the need for separate dedicated erosion protection components.
4Volume of stationary object
If cross-drill intersections are positioned close to internals components, then valve block size is reduced, but erosion damage risk increases
Solution Approach 1:
The flow path is designed with locally optimized geometry around cross-drill intersections and critical components. Specific sections feature gentle curves and expanded radii at intersection points to redirect flow away from vulnerable areas, while maintaining compact overall dimensions. This localized geometric optimization protects critical zones without increasing overall valve block size.

AI summary
A valve block may have a cross-drill intersection bore formed within the valve block by a first flow bore intersecting a second flow bore. Additionally, at least one insert may be within the first flow bore or the second flow bore. The at least one insert may include a wall contacting an inner surface of the first flow bore or the second flow bore, a passageway defined within the wall and having openings at opposite ends of the insert, and a plurality of vanes extending from an inner surface of the wall into the passageway. The one of the opposite ends of the at least one insert may align with a surface of the cross-drill intersection bore. The at least one insert may reduce and/or protect the bores within the valve block from erosional damage.
