The heating tube is made by inserting electric heating wire into the seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube, and then processing it into Various shapes required by users. It has simple structure, high thermal efficiency, good mechanical strength and good adaptability to harsh environments. It can be used for heating of various liquids and acid and alkali salts, and is also suitable for heating and melting of metals with low melting points (lead, zinc, tin, babbitt).
Classification of heating pipes：
1. According to the way of outlet, it can be divided into single-head electric heating tube and double-head electric heating tube.
2. According to the material classification, it can be divided into stainless steel electric heating tube, quartz electric heating tube, Teflon electric heating tube, titanium electric heating tube.
3. According to the shape classification, it can be divided into straight electric heating tube, U-shaped electric heating tube, L-shaped electric heating tube, W-shaped electric heating tube, fin electric heating tube, special-shaped electric heating tube.
4. According to the classification of use, it can be divided into dry-fired electric heating tube and water-fired electric heating tube.
5. According to the heating method, it can be divided into conventional resistance heating tube and radiant electric heating tube.
