1. Type A: Electric heating tube Type A is a high-temperature imported external winding electric heating tube, made of 304 material, with Cr20Ni80 heating wire, working temperature Less than or equal to 450 degree , and service life of about one year.

2. AA type: The AA type electric heating tube is an ultra-high temperature heating tube made of imported wire or Cr20Ni80, and the tube material is 316 or 310S. High temperature powder at 900 degree , working temperature around 550 degree , with a lifespan of over one year.

3. Type B: Electric heating tube Type B is a regular heating tube, usually made of 201 or 302 materials. The heating wire is 0Cr25Al5, with a service temperature of Less than or equal to 300 degree and a lifespan of more than 6 months.

1, Small size and high heating power.

2, It can heat various media in various occasions, such as explosion-proof situations.

3, The heating temperature can generally reach 720 degree .

4, The heating system can be fully automated, including controlling the electric heating system through the DCS system.

5, Long service life, with multiple protection systems, safe and reliable. Uniformly distribute high-temperature resistance wires in high-temperature resistant stainless steel seamless pipes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced, high thermal efficiency, but also generates uniform heat. When there is current passing through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesium oxide powder to the surface of the metal pipe, and then transfers to the heated part or air to achieve the purpose of heating.
