- Sep 29, 2020-

Dryer heating tube design and customization: The dryer heating tube is generally used in the working environment of dry air burning. Before the customized design, customers need to inform the specific size of the working environment, whether there is a temperature control device, and if so, what is the controlled temperature? Is there a fan circulation device? And the size of the installation space!


  1. Voltage and Wattage

  2. Pipe diameter, usually 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm

  3. Selection of finned types: square finned (25*50mm or 40*80mm) or winding finned (generally using 6mm, 10mm steel tape winding)

  4. Are fasteners required for double ends, and if so, what is the size?

  5. Material selection of outer pipe: the main material is 10# carbon steel, SUS304, SUS321, SUS316L, SUS310S (commonly known as: 2520), titanium pipe, etc.

  6. Fin material: 10# carbon steel, SUS3201, SUS304, SUS321, SUS316L

  7. Electric heating wire material selection: generally iron chromium aluminum wire, nickel chromium wire (generally H140, 2080 resistance wire, etc.). The choice of both depends on the customer's working environment (temperature and vibration).
