High Temperature Piping Support Pads

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.

Bright ideas?

Thanks
