Thanks Austsa, To large extent, the pipe was supported on the ground ( it was not fully unsupported for the total length of 20 m) and I guess to assume cantilever case (fixed end) is not realistic.
Thanks BigInch, but at least one can conclude that the pipe out-of-straightness (which we saw when we exposing the pipe prior to cutting) was due to physical pipe bending/beam bending (not that the original pipe profile was installed in that manner). In other words
If the pipe was not under...
Thank you very much for your thoughtful replies. Unfortunately we did not have intial profile of the pipe since the pipe was installed long time ago so we wanted to make sure of the out-of-straightness observed from geopigging when the pipe was exposed was not from initial installation but it...
Hi,
we had a large diameter steel gas-pipe that was installed in potentially unstable slope area. Our ILI geo pigging inspection data indicated that pipe may have deformed and experienced bending (that results in high stress close to yield) due to ground movement . We decided to mitigate the...
