Earlier this year, a valued client referred to Callidus to fix a repeating incident of failing valve inline due to external cyclic loading. Being categorised as a major and serious safety concern, an immediate solution was requested.
The process
Callidus engineers utilised the vibration data from previous assessments, and redesigned a valve body that can withstand cyclic loading over the equipment’s life expectancy.
A series of FEA study trials, focusing on fatigue failure and several dimensional adjustments, were performed to optimise the design.
The solution
At the end of the study, Callidus offered two option to the client:
- A body with the same Ti12 material. In this option, the weight of the body increased significantly due to the added mechanical reinforcements.
- A body upgraded Ti5 material. In this option, there is a minimal increase in the overall weight due to improved mechanical properties.
The outcome
The client responded positively with the outcome of the study and decided to install the option 2 modified design. And not only for their 600CL, but also on the 300CL locations.
