Anchor Point

Go to the "Search This Forum" box just to the right of the screen and type in "Expansion Loop" and read all you find there.

It might help

Guide support allows for longitudinal expansion and prevent lateral movement. As a design practice, a piping loop must be selected for a total expansion not more than 10".

Hey Abdel,

Did you mean to say 10 feet versus 10 inch ???

Hi Kimba.pa,

No, I mean that each expansion loop of a piping system shall be designed to compensate a max. of 10 inch. I mean when you have a calculated expansion more than 10", you are advisable to use more than one expansion loop, and the piping segments shall be furnished with an anchor support, to be located at the middle between the two loops.

Interesting I have never made and expansion loop that went that high that's good information, where did you get that data?

If I am understanding that correctly that would mean 5" of cold spring on each of the two legs?

No pipeit, you have it wrong.

Please let me try to explain what Abdel is talking about.

A) the total thermal expansion (from anchor to anchor) is 10". That means that 5" of expansion is on one side of the of the Loop and 5" of expansion on the other side of the loop.

b) If "Cold Spring" is used then you only "Cold Spring" one half of the expansion on each side of the loop. This means that you "Cold Spring" each side of the loop 2-1/2", not 5" on each side.

c) "Cold Spring" is not always used. Some people feel it is a good practice and some do not.

I see thanks for clearing that up.

Regards,
