the wedges sound messy, and they sound to be attached to the clamp which is
attached to base.
I'm thinking you mean insulated blocking and not tapered wedges.
actually the Gr.... support people have the concept and very very hint
similar product. a spider out from the pipe and high temp ins blocking in
between. called fig 256 "pipe slide".
these work well at high temp.
we've used link seal for high temp also, especially building penetration,
but invariably the fabs want to build all of these themselves, (rather than
purch) and i imagine thats what will happen in your case.Take a look at
Pipeshields.
This fellow in calif patented these and created the business. Its was sold
to Shaw Pipe protection.
and (was) found on shaw group pipe protection website. I now see its been
sold to Piping technology... the usual merry go round.
> Al:
> Thanks for reply. What we have here is a combination: adjustable pipe
wedges plus clamp, attached to concrete support. The pipe usually has a
wear pad bonded to the bottom, to avoid wear/corrosion between the pipe and
support wedges. Same on the pipe clamp, has pad bonded. With temperature
swing from ambient to 500 degrees, pipe grows longitudinally and moves in
relation to clamp. Possibly could weld on a sacrificial pad, but I'm
concerned about it galling and binding up to the clamp and support wedge.
So, I am looking for a non-metallic pad/clamp liner that will live at the
high temp.
