An exchanger end was running at 258°F ( 126°C ) before being insulated with HOT PIPE COATING ®. Petro Canada's objective was to reduce operating temperature to 120°F (49°C). HOT PIPE COATING ® was applied at approximately 250 mils / ¼" DFT (Dry Film Thickness), reducing operating temperature to 100°F (38°C), which exceeded expectations.
The recommended coating system consists of:
Prime coat: HOT PIPE COATING ® - 250 mils / ¼" DFT ( Dry Film Thickness )
Base coat: SUPERTHERM ® - 10 mils DFT
Top coat: SP SEAL COAT ® - 3 mils DFT
