The double-ended electric tubular heaters, with
their round cross-sectional geometry, are highly adaptable for
bending—especially when bending is performed in the field.
Double-ended tubular elements offer various combinations of resistor
coils and thermocouples inside one sheath. They have the ability to
sense the heater's internal temperature accurately every time, or
offer three-phase capability in one element.The resistance wire is
centered in the heater sheath and electrically insulated with
compacted, high-grade magnesium oxide for superior heating
performance. |
