Tube heater product introduction:

Tubular electric heaters are composed of metal tubes, spiral resistance wires, and electrical grade magnesium oxide powder with good thermal conductivity and insulation, as well as terminals. They are widely used for heating liquids, air, etc. Common ones include water heaters, ovens, coffee pots, etc.

Product materials：
The general material for the outer tube is In800, In840，304，316L，310S， Aluminum, copper, low-carbon steel, etc.
Magnesium oxide powder is selected in different specifications according to different usage requirements, including high-temperature powder, medium temperature powder, etc.
Resistance wire is a 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 easy to cut iron.
Sealing materials include epoxy, silicone, glass, etc.

productworkmanship:
A tubular heater is made by inserting electric heating wires into the outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gap with magnesium oxide powder with good thermal conductivity and insulation properties, and then shrinking the tube. After heat treatment process (some tubes do not need 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 acid-base salts, and is also suitable for heating and melting low melting point metals.
Scope of use of tubular heater: 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.

The tubular heaterAppearance classification：

Tubular heaters can be divided into straight single ended heating tubes, straight double ended heating tubes, U-shaped heating tubes, W-shaped heating tubes, special-shaped heating tubes, and spiral heating tubes according to their appearance
