4" Flange Heaters

Flange heaters consist of hairpin tubular elements welded or brazed into an ANSI pipe flange and provided with wiring boxes for electrical connections. Designed for use in tanks and pressurized vessels, flange heaters are commonly used for heating gases and liquids such as water, oil, heat transfer fluid, and corrosive solutions.

If you have any questions about flange heaters, or for questions or quote requests, you can call us at (866) 685-4443 or send us a contact form or an e-mail.

Please note that, before shipping any immersion heater, we will
email you to verify heater selection, and must receive your confirmation.
