load bearing insulation for high temperatures

pipe supports limited incorporate high temperature load bearing insulation in many designs of equipment. for instance where hightemperature piping is to be supported by pipe shoes incorporating slide bearings, such material will be utilised to reduce the temperature sufficiently at the bearing surface.
