Technical Data
   
   

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 applicaton, 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
- Temperature sensitive materials like glucose & liquid sugars
- Bulk storage of corrosive Material

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 TERMOCOUPLE 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 Heating Assemblies
Screw plug (SPA Series) 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 ½” NPT schedule 40 carbon steel in the standard designs. Stainless steel pipes and connection fittings are available for chemical corrosion for or immersion into food products.
