Expansion Loop Design - Anchor point placement 2

[nikolastrojman]

Hi!

I have a question regarding the expansion loop design and placement of anchor points. Does it make any sense to place an anchor in the middle of the expansion loop?

The conventional way (and the proper way) is to put anchor on both sides of the loop in order to use it´s inherent flexibility to reduce thermal expansion stresses and support displacements.
One of our subcontractors suggested to put it in the middle of the loop.

You need to run pipe stress analysis using various scenarios to determine what is best for your situation, this is a simple model. Are the critical seismic loads perpendicular to the pipe? Can you use an axial stops with lateral slides? If the line is heavy, you can use low friction pipe supports.
