Frangible Disk Configuration With Sleeve and Releaser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rupture disks in the resource recovery and fluid sequestration industries require high pressure for containment, leading to increased costs and ancillary difficulties due to the need for exceptional pressure-related releases, which can be costly and complex in well construction.
Innovation Solution
A frangible disk configuration with a housing, a sleeve, and a releaser that retains the sleeve in a fixed position until a threshold pressure is reached, allowing the sleeve to slide and contact the frangible disk for rupture, reducing the need for high-pressure containment and associated costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high pressure is used for containment before rupture, then the barrier function is improved, but the cost and complexity of well construction increase
Solution Approach 1:
The releaser is pre-configured to detach at a predetermined pressure threshold, automatically initiating the rupture process without requiring complex high-pressure containment systems. The sleeve is pre-positioned to slide and contact the frangible disk once the releaser detaches, ensuring reliable barrier function at lower pressures.
Solution Approach 2:
The releaser acts as an intermediary mechanism between the pressure source and the frangible disk. It mediates the pressure transmission by detaching at a specific threshold, allowing the sleeve to then slide and rupture the disk without requiring the full high-pressure containment system.
2Reliability
If high pressure is used for containment before rupture, then the barrier function is improved, but the cost increases
Solution Approach 1:
The releaser is pre-configured to detach at a predetermined pressure threshold, automatically initiating the rupture process without requiring complex high-pressure containment systems. This preliminary setup reduces manufacturing costs while maintaining reliable barrier function.
Solution Approach 2:
The system is designed to self-activate at a predetermined pressure threshold without requiring external intervention or complex high-pressure containment infrastructure. The releaser automatically detaches and the sleeve slides to rupture the disk, reducing manufacturing and operational costs.
3Manufacturing precision
If a releaser is used to retain the sleeve in a fixed position, then the controlled rupture at threshold pressure is improved, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional components: the releaser for pressure threshold detection, the sleeve for sliding motion, and the frangible disk for rupture. This segmentation allows each component to perform its specific function with relative simplicity, achieving precise pressure threshold control without overall system complexity.
Solution Approach 2:
The releaser serves as an intermediary mechanism that simplifies pressure threshold control by automatically detaching at the predetermined threshold. This intermediary function reduces the complexity of precisely controlling the rupture pressure compared to direct mechanical linkages.
