Your opinion about this accident bending
(OP)
I have an inspection work, for which I inspect the fireproofing network, someone could give me your opinion on what happened here? I ruled out the wind speed is 2m / s so I do not think that was material, the fluid is water at 25 º C normally sometimes the pipe surface temperature reaches 50 º C, so I guess no dilatation
I appreciate all your comments.

RE: Your opinion about this accident bending
This is a case of poor design (No pipe guides at alternate pipe supports) and natural causes (Thermal expansion due to Solar radiation).
There is also the possibility that there is some kind of restraint at both ends of this long run.
RE: Your opinion about this accident bending
It would be helpful to see what is happening at each end.

Are you in a seismic zone?

Seriously, its acceptable to deliberately allow for snaking, if the stress allowables are not exceed (snaking reduces stress) and the plant manager does not consider himself a perfectionist, such that all pipe must permanently remain either parallel to, or at right angles with plant north.

No lateral restraints -> so the pipe twisted sideways, not "up" so it didn't even have gravity to try to pull it back down.
30 degree C rise (from ambient (?)) at 20 degrees in the morning = (roughly) 60 degrees F change. It is enough.
(Unless there is a "moderately large" magnet on one side of the pipe pulling all the pipes that way. Check your compass before looking further. 8<)
