Strain/Deformation Measurement

Strain/Deformation Measurement

Strain/Deformation Measurement

(OP)
Hey all, I am looking to see if there are simple options to monitor online strain, strain rate, deflection or swelling.  I have a steam pipe that was deformed by an impact.  Most of the pipe was replaced but a small section that was away from the impact has to stay online for a few years.  I would like to monitor it without using high temperature strain gaging.  Anyone have any input.  Thanks in advance for your comments.

RE: Strain/Deformation Measurement

Reality check:  Seems like if you're really serious about wanting to monitor strain on that piece of pipe, you need to be shutting down and replacing it now.

0.001 inches = 30,000 psi stress.  Looks to me like you need those strain gages... or a blue laser micrometer.
