Application: Steam Reclaiming Valve Springs
Problem: Existing 17-7 ph Stainless steel spring design was breaking in operation.
The MWI Solution:
- Performed extensive testing and failure analysis
- Developed replacement spring design using Inconel 718
- Implemented component-specific load testing procedures to ensure 100% compliance with very tight load requirements
Understanding the cause of the failure necessitated the change in material, which resulted in a higher cost component, but the new design has eliminated the prior spring failure and the associated maintenance costs.
