HDPE PIPE SUPPORTING

Hi friends
Actually recently I am involved in a polyethylene piping system in a mineral plant. I found an interesting supporting for these pipe, Continuous Support of PE Pipe. I attached this support sheet to this note and ask you some questions if anyone has same experience in such project.
1- the thermal expansion for polyethylene pipe is different with steel. in this case pipe tightly clamped around the pipe and also welded to beam support.
2- what should we do for slot piping? should we use shoe support under profile?
3- should we guide and stop the system by supporting profile?

i hope if you guide me and also send me or refer me to standard, image, specification or anything.

best wishes

There is no official codified guidance available for HDPE piping, unless your piping manufacturer offers it, and therefore no support for it exists officially in CAESAR.

Unofficially, you might be able to rig a model to emulate this for purposes of calculating sag and clamp loads only, but it won't qualify the pipe or the steel the pipe sits on. That would have to come from somewhere else.

1.PE Pipe thermal expansion is mostly 10 times of C/S. For exact value, check with vendor. Tight clamp welded to structure sounds like an anchor to me. Do you prevent the solar effect to the pipe? if not your pipe can be heated up to 50~80℃. Either pipe or support will suffer from it.

2.Not sure what is slot piping. Are you saying that the coupling in your drawing is not fixed?

3. Guide support is possible, but stopper it's complicated. Check out the PPI(https://plasticpipe.org/)

How long is your pipe line? If line is long enough, I strongly recommend you to bury them.
