Detailed Description
Project Background
The equipment operates long-term under high-temperature, vacuum, or corrosive process environments.
Due to inappropriate material selection and welding methods, the original sheet-metal structures gradually suffered from deformation, weld fatigue, or sealing failure, resulting in reduced equipment stability and potential impact on process yield and uptime.
Furthermore, differences in mechanical load, thermal expansion, and structural tolerance among various equipment modules make standardized sheet-metal designs or single-material solutions insufficient for real operating conditions.
Improvement Approach
- Re-evaluated sheet-metal material properties based on actual operating conditions (temperature, vacuum, chemical exposure, and structural loads)
- Selected suitable combinations of metal and non-metal materials to meet high-temperature, corrosion resistance, and structural rigidity requirements
- Redesigned welding methods according to load distribution to reduce stress concentration and deformation risks
- Optimized sheet-metal structure design and fabrication tolerances to support assembly and maintenance requirements
- Incorporated long-term operation and maintenance considerations into the design phase for overall reliability evaluation
Results
- Significantly improved long-term structural stability and reliability of sheet-metal assemblies
- Reduced abnormal risks caused by weld fatigue or improper material selection
- Enhanced sealing performance and structural consistency, minimizing unexpected downtime
- Extended component service life and reduced overall maintenance and replacement costs
- Improved long-term equipment performance under actual process environments
All projects are custom-designed based on actual equipment operating conditions and process requirements.
