In previous articles titled "Several Classification and Introduction of Single-Head Electric Heating Tubes" and "Detailed Introduction of Single-Head Heating Tubes Based on Four Classification Criteria," we provided essential knowledge about these devices, which have gained popularity among many clients. Through those articles, readers were able to understand the range and functions of different types of electric heating tubes. Comparing them also helps in better understanding their applications and benefits.
This time, we'd like to share more information about the technical characteristics of electric heating tubes and the design and customization options available for single-head heating tubes.
Depending on the working conditions of the equipment, different grades of high-temperature resistant stainless steel are used for the electric heating tubes. Since the tubes operate at high surface temperatures, it's crucial to ensure proper insulation and minimize leakage current. This requires a precise production process and effective sealing techniques. The key technical features include:
1. **Final Use Condition**: Suitable for dry burning.
2. **Material Options**: Stainless steel grades such as SUS304, SUS321, SUS310S, INOC800, and INCO840.
3. **Outer Diameter Range**: 2.0 mm to 20.0 mm.
4. **Sealing Methods**: Available in EPOXY (epoxy resin) or GLASS (glass) sealing.
5. **Electrical Performance**: Insulation resistance over 10,000 MΩ after being stored in a cold room for over one year, with leakage current below 0.5 mA.
Electric heating tubes used in equipment that generates sparks, arcs, or dangerous temperatures during normal operation—especially those with power over 250W or current over 5A—are classified as Class I electrical equipment. These must be connected to the main unit via a junction box, which is designed to connect cables or wires to the electrical components. Explosion-proof junction boxes are widely used in such cases. The inner walls of the junction box should be coated with arc-resistant paint, and the explosion-proof joint surfaces must be treated for rust prevention. Additionally, the electric heating tube itself should be coated with anti-rust oil.
The single-head heating tube, also known as an L-type single-head electric heating tube, is a specialized form of the standard single-head design. It is commonly used in plastic packaging, small mold heating, injection nozzle heating, hot pressing machines, cigarette machinery, semiconductor eutectic welding, die casting input tunnels, and sprue-free injection systems. It also provides cooling effects when gases expand.
**Design and Customization of Special-Shaped Single-Head Heating Tubes:**
1. **Material Options**: Mainly made from SUS304, SUS321, and SUS316.
2. **Pipe Diameter**: Can be manufactured between 4 mm and 25 mm based on customer requirements.
3. **Tube Length**: Can be up to 2500 mm.
4. **Additional Features**: Lead length, fasteners, threads, and other customizations can be tailored to suit individual needs.
Through this detailed introduction, we hope to provide a clearer understanding of the technical characteristics and customization possibilities of single-head heating tubes. If you need further information or assistance, feel free to contact Yancheng Hongtai Alloy Electric Co., Ltd.

Solar Light
Solar street lights have several advantages over traditional street lights. Here are some of the benefits of solar street lights:
Solar street lights do not require cables, AC power supply, or electricity charges. Adopt DC power supply and control; It has the advantages of good stability, long life, high luminous rate, easy installation and maintenance, high safety performance, energy saving and envi
ronmental protection, economic and practical.
Energy-efficient: Solar street lights are powered by renewable energy from the sun, making them highly energy-efficient and eco-friendly. They do not require electricity from the grid, which reduces electricity bills and carbon emissions.
Although the initial cost of installing solar street lights may be higher than traditional street lights, they are more cost-effective in the long run. They require minimal maintenance and have a longer lifespan, reducing replacement and repair costs.
Solar street lights are easy to install and can be installed in remote areas without access to electricity. They do not require any wiring or trenching, which makes the installation process quick and hassle-free.
Solar street lights provide better visibility on roads and sidewalks, making them safer for pedestrians and drivers. They also reduce the risk of accidents and crime in poorly lit areas.
Solar street lights are equipped with batteries that store energy during the day and provide power at night. They are designed to work even in cloudy weather and can provide illumination for several nights without sunlight.
