Removable Circular Reinforcement for Defective Pressure Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reinforcing pressure equipment with structural defects are complex, require downtime for implementation, and can compromise the mechanical integrity of the equipment, with potential safety risks from coating failure.
Innovation Solution
A removable reinforcement device comprising circular arc portions and supports is applied to the structure, using removable assembly means to form a circular reinforcement around the equipment, ensuring easy installation and removal without damaging the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current repair techniques are used to reinforce pressure equipment with structural defects, then the structural integrity can be improved, but the implementation complexity increases and equipment downtime extends
Solution Approach 1:
The reinforcement device is divided into multiple modular components including circular arc portions, supports, and removable assembly means. This segmentation allows the device to be assembled in sections around the pressure equipment, simplifying implementation while maintaining structural integrity. The modular design enables easier handling and installation compared to applying a complete coating system.
Solution Approach 2:
The invention extracts the reinforcement function from the pressure equipment itself and implements it through an external removable device. Instead of permanently modifying the equipment through coating application or welding repairs, the reinforcement is achieved by adding a separate circular reinforcement device that can be installed and removed independently, reducing implementation complexity.
2Reliability
If current repair techniques are used to reinforce pressure equipment with structural defects, then the structural integrity can be improved, but the equipment must be completely shut down and dismantled for extended periods
Solution Approach 1:
The reinforcement device incorporates removable assembly means that allow for dynamic installation and removal. The device transitions from a non-removable state (coating or welded repair) to a removable state, enabling quick installation around the defect area and equally quick removal when no longer needed, significantly reducing equipment downtime while maintaining structural integrity during operation.
Solution Approach 2:
The circular arc portions are positioned specifically around the structural defect area rather than requiring complete equipment dismantlement. This localized approach reinforces only the necessary region while leaving the rest of the equipment operational, minimizing downtime and avoiding unnecessary disruption to non-defective areas.
3Reliability
If coating is deposited by cold thermal spraying to reinforce pressure equipment, then the structural defects can be addressed, but the coating may break under pressure and project debris, compromising safety
Solution Approach 1:
Instead of applying a coating that mimics reinforcement, the invention uses a physical circular arc structure that actually provides the reinforcement. This solid structural copy replaces the functional coating approach, eliminating the risk of coating failure and projectile formation while maintaining the reinforcement effect.
Solution Approach 2:
The reinforcement device is designed as a removable component rather than a permanent coating. This disposable-style approach allows the reinforcement structure to be installed only when needed to address defects, removed when no longer required, and replaced if damaged, eliminating safety risks associated with permanent coating failures while maintaining cost-effectiveness.
