Flow Conduit Insert Positioning for Real-Time Erosion Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Erosion in pipes and flow conduits due to entrained solids causes material loss, production stoppages, and increased costs, with existing solutions like additional thickness or coatings failing to effectively mitigate erosion, and flow directing elements often failing due to erosion themselves.
Innovation Solution
A system with a movable insert, such as an index plate with replaceable wear inserts, is placed within the flow conduit to alter the fluid flow, including mechanisms to adjust its position, which can disrupt flow patterns, reduce wear rates, and extend the effectiveness by rotating or replacing worn surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If additional thickness or erosion resistant coating is added to the flow conduit, then the service life of the conduit is extended, but the device complexity and cost increase
Solution Approach 1:
The flow conduit is segmented into a permanent housing and a replaceable insert component. The insert can be removed and replaced when worn, extending the service life of the conduit without requiring replacement of the entire system. This segmentation allows the wear-prone portion to be independently maintained.
Solution Approach 2:
The insert includes adjustable flow directing elements whose position and configuration can be changed to optimize flow patterns under different operating conditions. This adaptability allows the same insert to effectively mitigate erosion across varying flow rates and solid concentrations, extending its useful life.
2Object-affected harmful factors
If flow directing elements are added to alter flow pattern, then erosion is mitigated, but the elements themselves fail due to erosion
Solution Approach 1:
The flow directing elements are segmented into a replaceable insert that can be removed and replaced when worn. This allows the erosion-prone elements to be maintained independently from the permanent housing, ensuring continuous operational reliability.
Solution Approach 2:
The insert includes movable or adjustable flow directing elements that can be repositioned or reconfigured as they wear, allowing optimization of their protective function throughout their service life rather than being fixed in a single position.
3Adaptability or versatility
If the movable insert is made adjustable, then adaptability to changing flow conditions is improved, but the device complexity increases
Solution Approach 1:
The insert incorporates movable elements with adjustable positions that can be modified to adapt to changing flow conditions, solid concentrations, and erosion patterns. This dynamic adjustability allows optimization of erosion mitigation without requiring multiple different inserts.
Solution Approach 2:
The single replaceable insert design serves multiple functions: it directs flow to protect the housing, provides a sacrificial wear surface, and can be adjusted to handle various flow conditions. This multi-functionality reduces the need for multiple specialized components.
4Ease of repair
If replaceable wear inserts are used, then maintenance becomes easier, but the initial device complexity increases
Solution Approach 1:
The insert is designed as a separable component that can be easily removed from the housing for replacement when worn. This segmentation enables simple maintenance operations without requiring specialized tools or procedures, and the modular design actually simplifies the maintenance process despite adding an initial component.

AI summary
Apparatus and systems for mitigating erosion in flow conduits, and may include a housing including a fluid inlet and a fluid outlet and a flow path there between. A movable or static (passive) insert is disposed within the housing and may be configured to alter a flow of a fluid passing from the fluid inlet to the fluid outlet. The apparatus may also include a mechanism to adjust a position of the movable insert.
