The single-end heating pipe manufacturer has a long-term name in China's electric heating industry: M3. In the late 1990s, due to the wide application of electric heat pipes in China, the shape of electric heat pipes is also many.

Single-end outlet heat pipe is suitable for working in heating medium which can not be connected at both ends, such as high and low temperature insertion heating of various sizes of dies and mechanical equipment, including punching dies and other dies, medical devices, plastic sealing machine, bottle sealing machine, continuous automatic sealing machine, cigarette making machine, etc. Mainly as follows:

Used for drying wood, paper, printing and dyeing, paint residue, etc.

Melting heating of nitrite and other salts.

Melting low melting point alloys, such as lead melting furnace, tin melting furnace, etc.

Building heating.

Infrared radiation heating device.
