Spring Installation near Strain Sensitive Rotating equipment - 10/13/17 05:17 PM
Hi Fellas,
I look forward to hear from people on their approach to install Spring hangers near strain sensitive equipment after hydro testing. Please note the springs has cold load as set load. Few points to touch would be when releasing the lock-nut, how do you make sure equipment is not damaged due to large transfer of forces and moments (if nozzle is loosely bolted for alignment checking). also how you do the cold load setting - using turnbuckle or nut above spring piston plate?
Would appreciate response from someone who has actually done it in the field, as already have heard different stories from design people (speculative but not firm)
Cheers,
