 Pipe Insert Heaters use an ANSI flanged heater or an NPT screw plug heater mounted inside a pipe. These offer you the advantages of direct immersion heaters with the benefit of being able to service the heater without draining the tank. The Incoloy sheathed element(s) inside the pipe are carefully designed for this application, and transfer their heat to the inside pipe wall by convection and radiation. The large surface area of the pipe in contact with your liquid greatly reduces the intensity making the pipe insert heater ideally suited for heating:
– Very viscous materials like Bunker C Fuel Oil |

Sheath Materials
| Incoloy 800 ® | Incoloy 800 is used for all pipe insert heating applications. Maximum sheath temperature 1400ºFWATT DENSITY Watt.in² 10 – 30 |
Terminal Housing
| Therminal Housings | NEMA 1 Sheet Metal Housing (Indoor use only)
NEMA 4 (Standard) Moisture Resistant Terminal Housing NEMA 4X Epoxy Painted or Stainless Steel Moisture Resistant Terminal Housing NEMA 7 Hazardous Location Terminal Housing |
Built In Thermostat Options
| Power Ratings | Up to 240 volts, 25-amp double pole, singel throw (DPST)
Up to 600 volts, 15-amp triple pole, single throw (TPST) |
| Temperature Ratings | 320 – 700° F |
| Thermostat Application | Since the thermostat will be located inside the pipe, it will be measuring the internal pipe temperature. The thermostat is intended for high limit purposes and is not suitable for process control. |
Built In Thermocouple Options
| Sensors | “K” calibration thermocouple for high limit sheath protection. Since the thermocouple will be located inside the pipe, it will be measuring the internal pipe temperature. The thermostat is intended for high limit purposes and is not suitable for process control. |
Screw Plug and Flanged Assemblies Complete with Pipe
| Complete Pipe Assemblies | Screw Plug and Flanged assemblies are available complete with a pipe when installation of a pipe into the tank is not feasible or desirable. The pipe wells are 2″ or 2 1/2″ NPT schedule 40 carbon steel in the standard design. Stainless steel pipes and connection fittings are available for chemical corrosion or for immersion into food products. |
