Product Details

Single-head heating tube

The single-head heating tube can be used as an electric heating element in various equipment, including new energy vehicle heating, lithium battery packaging machinery, smokeless barbecue stoves, plastic molding molds, hot pressing machinery, cigarette machinery, pharmaceutical machinery, shoe manufacturing industry, 3D curved glass molding machines, 3D printers, packaging machinery, extruders, and more. All models are manufactured according to CE standards.

Product Features:

1. Long service life: Advanced internal design, using imported high-purity magnesia rods and filling materials with excellent thermal conductivity for uniform and efficient heating.
2. Special grinding equipment is used to ensure precise dimensions and tight assembly with the equipment, resulting in high thermal efficiency and fast heat dissipation.

  • Diameter tolerance D: +0-0.05mm
  • Length tolerance L: +1-1mm
  • Capacity tolerance W: +5%-10%
  • Flatness requirement: ≤3% (The deviation between the tube wall and the highest point from the centerline should be ≤3mm when a 1-meter-long heating tube is placed on a horizontal plane.)
  • Insulation resistance: ≥103MΩ
  • Dielectric strength: 1800V/S
  • Packaging requirement: Vacuum packaging
