Northern Natural Gas has over 2,000 heat exchangers suffering from CUI.  The client was looking for an alternative to conventional jacket insulation due to severe corrosion and maintenance costs.  HOT PIPE COATING has been applied on dozens of heaters since 2018 with specifications to replace every heater with HOT PIPE COATING.

300 mils DFT of HOT PIPE COATING, 8 mils DFT of ENAMO GRIP

Reduced Corrosion Under Insulation, improved insulation as seen in jump in water bath temperatures and increase in metal temperatures (see pictures)
