How to Anchor PVC and CPVC Pipe

How to Anchor PVC and CPVC Pipe

How to Anchor PVC and CPVC Pipe

(OP)
I'm trying to find a way to anchor runs of PVC and CPVC piping, where there will be an expansion loop midway between anchors.  The anchors will be used to secure the pipe so I can take up the thermal growth with expansion loops.  I am looking at a pipe clamp, Cooper B-Line B2000 Series, that is used in a Uni-strut support.  The problem with the B2000 type of clamp is that it will only hold an axial reaction of 150 pounds.  My reactions will exceed that.

Some data:
a) typical pipe sizes are 3/4 to 4 inch, Schedule 40.
b) pipe materials are PVC and CPVC.
c) installation temp = 50 degrees F.  Operating temp = 130 deg F.
d) pipe run between anchors = 40 feet.

Any ideas out there?

Make a steel backing plate for a PVC Flange Fitting and run extra long flange bolts through the flange and the backing plate.

Make a concrete encasement around a slip joint.

Other ideas,

Thanks, BigInch.  Excellent reference.

RE: How to Anchor PVC and CPVC Pipe

If you load is in excess of 150lbs you may find the material challenged and will buckle.

RE: How to Anchor PVC and CPVC Pipe

I recall seeing a procedure where "shoulders" made from split pipe were solvent welded either side of a standard pipe clamp to act as anchors, but can't find the reference offhand.  The clamp was not tight to the pipe, more as a guide.  I'd check Chemtrol (Nibco) or Harvel, both have pretty good technical info on their websites.

As an aside, if you are operating at 130 Deg F, I'd stay away from PVC.  It is only rated to 140 maximum.

jdarco: thanks for the "shoulders" tip.  Also, you are 100% correct: forget about PVC at 130 degrees F; use CPVC instead.  That was my brain fart for the month.
