ABSTRACT:
An improved resistance heater tube for use in heating process streams uses a moisture impermeable and heat resistant insulating material on the cold pin section to prevent shorting of the heater. In a heater tube hollow tubing to surrounds wire resistance elements and a non-conductive and heat resistant packing fills the tube to insulate the wire from the tube wall. Air permeates the packing to allow proper oxidation of the resistance wiring. Cold pins provide terminal ends for electrically connecting the wire ends to a power source. The cold pins extend into the Tube through the packed material and connect with the wire. The water impermeable coating covers cold pin at the tube end to prevent water absorption from grounding the cold pin to the tube wall and shorting out the heating element.
