Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bonding urethane layers to flow equipment are difficult and result in equipment needing replacement when damaged, leading to downtime and inefficiency, especially in erosive environments.
Innovation Solution
Erosion-resistant inserts with internal structures and polyurethane coatings are designed to fit within flow equipment, providing mechanical engagement and sealing features to secure and protect against erosion and corrosion, extending equipment life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If urethane coating is applied to flow equipment using bonding methods, then erosion resistance is improved, but manufacturing complexity and difficulty increase
Solution Approach 1:
The flow equipment is divided into modular sections with removable urethane liners. Each liner can be independently installed and replaced without affecting the entire equipment structure. This segmentation simplifies the manufacturing process by allowing separate production of liners and equipment bodies, then assembling them through mechanical retention features.
Solution Approach 2:
A retention system acts as an intermediary between the urethane liner and the flow equipment structure. This intermediary mechanism (comprising retention members, engagement features, and sealing elements) facilitates easy installation and removal of liners without requiring complex bonding processes, thus improving ease of manufacture while maintaining erosion resistance.
2Reliability
If entire equipment is replaced when urethane layer is damaged, then erosion protection is maintained, but loss of time and productivity increase
Solution Approach 1:
The urethane protective layer is segmented into removable liners that can be independently replaced. When a liner becomes damaged, only that specific liner needs to be removed and replaced, not the entire flow equipment. This dramatically reduces maintenance time and equipment downtime while maintaining continuous erosion protection through staggered replacement of multiple liners.
Solution Approach 2:
The design allows for easy discarding of worn urethane liners and recovery/reinstallation of serviceable components. The modular structure enables rapid removal of damaged liners and installation of new ones, minimizing equipment downtime. The retention system facilitates quick disassembly and reassembly, allowing maintenance teams to efficiently replace only the worn protective layers.
3Reliability
If urethane coating is applied to entire equipment, then complete coverage is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The protective system is segmented into multiple removable liners rather than a single complex integrated coating. Each liner is a simple, standardized component that can be manufactured independently and installed in modular sections. This segmentation reduces device complexity by breaking down the protective system into manageable, interchangeable parts while maintaining complete coverage through proper arrangement of multiple liners.
