I. Overview of High-Density Single-Head Heating Tube
Features of High-Density Single-Head Heating Tube: Fast heating, working temperature ≤450°C. Applications: Plastic molding dies, C02 decompression assembly, cigarette machines, quick sealing machines, pharmaceutical machinery, etc. Voltage: 36-250V Power: 8-20W/cm2 (surface area of effective heating zone) Recommended specifications: 6︿20×40︿100
II. Selection Principles for High-Density Single-Head Heating Tube Materials
Temperature and corrosion resistance: For low-temperature tubes, BUNDY, aluminum, or copper tubes are generally used; for high-temperature tubes, stainless steel or Incoloy tubes are used. Incoloy 800 heating tubes can be used in poor water quality conditions; Incoloy 840 heating tubes have good oxidation resistance at high working temperatures and good corrosion resistance.
III. The Most Intuitive Method to Verify the Quality of Heating Tubes
First, wipe the surface of the heating tube clean, then connect to AC 220V power supply and dry burn in air. After the surface turns red, cut off the power. When the heating tube is completely cooled, wipe it with a tissue. If there is no black oxide powder (not reacted with oxygen in the air) on the white paper, it indicates that the heating tube is of high quality.
IV. Origin of SUTE0189 Single-Head Heating Tube
(Single-head) or (Cartridge) heating tubes (Cartridge Heaters) have a long-standing model in the Chinese electric heating industry: M3. In the late 1990s, due to the widespread application of heating tubes in China, many shapes emerged. In southern China, this type of heating tube with one end leading out for molds was called single-head heating tube, which is very descriptive. Abroad, it is called cartridge heater, also a descriptive name because the cartridge shell is cylindrical with one end sealed, similar to the Chinese term single-head heating tube.
V. Performance Requirements for High-Density Single-Head Heating Tubes
1 Heating time: Under test voltage, the time for the element to rise from ambient temperature to test temperature should not exceed 15 minutes.
2 Rated power deviation: Under full heating conditions, the deviation of the rated power of the element should not exceed the specified range below.
3 Insulation resistance: At factory inspection, the cold insulation resistance should not be less than 50MΩ.
4 Dielectric strength: The element should be maintained under specified test conditions and test voltage for 1 minute without flashover or breakdown.
SUTE0189 Single-Head Heating Tube
Far-infrared heating tubes use specially processed milky white quartz glass tubes with resistance alloy materials as heating elements. Since milky white quartz glass can absorb almost all visible and near-infrared light radiated by the heating wire and convert it into far-infrared radiation. However, current industrial infrared heating tubes have basically eliminated milky white quartz tubes because their material is brittle and cannot form long milky white heating tubes. Moreover, the milky white color has a shading effect, blocking heat. Due to the high tube wall temperature, it is only suitable for near-infrared heating.
Technical Features:
1. No need for far-infrared coating, good spectral radiation matching absorption characteristics, long-term use without radiation performance degradation, high electrothermal conversion efficiency. Energy saving of about 30% compared to ordinary heating elements.
2. High working temperature, wide selection range. Among them, the type sealed with ceramic caps has a maximum temperature resistance of 800°C.
3. Fast heating, low thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life, high insulation strength.
4. Pollution-free, a clean heater, meeting the requirements of modern high-paced, high-quality production, suitable for household appliances with high hygiene requirements.
5. Design, manufacturing, and installation are very convenient, economical and safe.
