Quick-change wear sleeve for high-pressure fluid conduit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure fluid conduits used in oil and gas wells experience severe wear due to abrasive particles, particularly in areas with turbulent flow, leading to erosion and requiring time-consuming refurbishment processes.
Innovation Solution
A quick-change wear sleeve system featuring a hardened cylindrical sleeve with a retainer ring that securely engages with a complementary groove in the fluid conduit, allowing for easy installation and removal, reducing wear and extending the conduit's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional refurbishment methods are used for high-pressure fluid conduits, then wear resistance is improved, but time consumption and skill requirements increase
Solution Approach 1:
The wear protection function is segmented into a separate replaceable sleeve component that can be independently installed and removed from the fluid conduit, allowing quick refurbishment without replacing the entire conduit assembly
Solution Approach 2:
The wear sleeve is designed as a consumable component that can be quickly replaced when worn, rather than attempting to refurbish the expensive main conduit body, reducing both time and cost of maintenance
2Reliability
If complex refurbishment procedures are implemented, then wear resistance is improved, but operational complexity increases
Solution Approach 1:
The retention system uses a dynamic compression mechanism where the C-shaped clip can be compressed to release and naturally springs back to secure the wear sleeve, allowing simple tool-free installation and removal
Solution Approach 2:
The complex retention mechanism is extracted into a separate C-shaped clip component that can be independently applied and removed, simplifying the overall installation process while maintaining secure attachment

AI summary
A quick-change wear sleeve for a high pressure fluid conduit is retained in a fluid passage of the fluid conduit by a resilient retainer ring received in complementary grooves in an outer surface of the quick-change wear sleeve and an inner surface of the fluid passage.
