This pipe is 400 F \ 204 C inside. It is insulated with HPC® COATING which brought the surface temperature down to 100 F \ 38 C with a thickness of only 550 mils\ 1/2 " \ 14 mm DFT. HPC eliminates CUI (Corrosion Under Insulation) as it is totally bonded to the surface and the top coat seals out air and moisture.
