Are EXPANSION JOINTS necessary in piping with small temperature change ?
Are EXPANSION JOINTS necessary in piping with small temperature change ?
(OP)
Hello everybody,
I am investigating whether the use of expansion joints is necessary in a certain piping system.
To be more precise:
Material = Steel
L = 20 m
Delta T = 25 K
Delta L = 5.75 mm (due to temperature effect)
Test pressure = 12 bar ( Working = 6 bar)
So far I have come to the conclusion that the expansion joint is not necessary if we have sufficient routing/elbows and that the axial expansion load is compensated by natural flexibility of the system.
Also, I was wondering if the flange connections can take any axial expansion load or they are the same as anchor points ?
Thanks,

I am on my last year of studying a double degree on Building, Business Management and Administration, and yesterday in the Installations subject we were just talking about expansion joints.
I can't answer your question with total certainty based on the data you provide, but I comment the advice that our teacher told us, and it was that whenever we can and if we doubt, we should always put expansion joints on that critical points.
Anyway I let you here this link: https://www.corzan.com/blog-sp/considerar-expansio... ; that belongs to a company which is specialized in piping.
So I hope that you could find some useful information there.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?

Refer Design of piping system by M W Kellogg for flexibility analysis of piping loops and decide based on that.
