HRY14 Sheath Type Heater Device
Function
It is made by placing electric heating wires inside an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube. After heat treatment (some tubes do not require it), it is processed into various shapes as needed by the user. It has a simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, as well as for melting low-melting-point metals.

Appearance Classification
Heating tubes can be classified by appearance into: straight single-end heating tubes, straight double-end heating tubes, U-shaped heating tubes, W-shaped heating tubes, special-shaped heating tubes, spiral heating tubes
Manufacturer Introduction:
Electric heating tubes, also known as heating tubes or heating elements, are tubular electric heating elements. They are made by placing coiled heating wires (resistance wires) inside a metal tube, filling the surrounding gaps with insulating powder (MgO) that has good heat resistance, thermal conductivity, and insulation. The ends of the heating wires have lead-out rods or wires. They have a simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. They are widely used in various devices such as saltpeter tanks, water tanks, oil tanks, acid-base tanks, melting furnaces for fusible metals, air heating furnaces, drying furnaces, drying ovens, and hot pressing molds.
