It is composed of a metal tube, spiral resistance wire, and electrically grade magnesium oxide powder with good thermal conductivity and insulation, as well as terminals. It is widely used for heating liquids, air, etc. Common applications include water heaters, ovens, coffee pots, etc.
Product Materials:
Common materials for the outer tube include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected in different specifications according to different usage requirements, such as high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, and there are generally two types of materials: Ni-Cr wire and Fe-Cr-Al.
There are generally two types of lead terminal materials: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Product Process:
It is made by inserting an electric heating wire into 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 required 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 acids, alkalis, and salts, and is also suitable for heating and melting low melting point metals.
Scope of use: Suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low melting point alloys. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, easy installation, safety and reliability.
Shape classification: Heating tubes can be classified according to different shapes: straight single-end heating tube, straight double-end heating tube, U-shaped heating tube, W-shaped heating tube, special-shaped heating tube, spiral heating tube
Technical Parameters:
Tube diameter: 12mm (for other diameters, contact customer service, generally in stock)
Fin outer diameter: 24mm
U-shaped single side length: 500W:
