Al,
Look for Lubrite in the web. It will help you out. They have copper plates
with graphite inserts for the kind of application you are describing. I have
used them for HP Steam pipe supports.

Asunto: Re: [PipingDesign] High Temperature Piping Support Pads
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.

sorry george, dont understand
everybrand Fig 295 hgr good to 750F ++alloy to 1050F . some brands go
slightly higher.
whats wrong with steel on steel? it only gets tricky on high temp supports
>1200F such as for high press high temp steam and other specialty high
temp
stuff.
if you need low friction use polished ss wear / slider plates for really
hi
temp.
cheers

> Anyone have any experience with high temperature pipe support/insulation
pads? I have a job that is heating natural gas to about 500 degrees (F),
for regenerating a dry bed dehydration unit. I have worked with EZline
pipe
supports, clamps and wedge systems, which are variants of fiber reinforced
plastic (FRP), and limited to around 400 degrees. Any one have experience
in steam plants or such - teflon or other materials for lining clamps, or
what? I can try insulating pipe, but then I can't get a good solid
retainer/anchor.
