In previous articles such as "Several classifications and introduction of single-head electric heating tubes" and "A detailed introduction of single-head heating tubes based on four classification criteria," we have covered some basic knowledge about single-head electric heating tubes, which has been well-received by many of our customers. Through these articles, readers were able to understand the range and functions of different types of electric heating tubes. Comparing them also helps in gaining a clearer understanding of their applications and benefits.
This time, we would like to share more insights into 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 in the manufacturing of electric heating tubes. Since these 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 to guarantee the following technical features:
1. The final use condition of the electric heating tube: suitable for dry burning.
2. Materials used: Stainless steel grades such as SUS304, SUS321, SUS310S, INOC800, and INCO840.
3. Outer diameter: Ranges from Φ2.0 mm to Φ20.0 mm.
4. Sealing styles: Epoxy resin sealing or glass sealing.
5. Electrical performance: Insulation resistance exceeds 10,000 MΩ after being stored in a cold room for over one year, and leakage current is less than 0.5 mA.
Electrical equipment that generates sparks, arcs, or dangerous temperatures during normal operation, especially those with a power rating above 250W or current exceeding 5A, falls under Class I electrical equipment. Such devices must be connected to the main unit through a junction box. The junction box is designed for connecting cables, wires, and electrical components. Explosion-proof wiring boxes are widely used in such cases. The inner walls of the junction boxes should be coated with arc-resistant paint, and the explosion-proof joint surfaces must be treated with anti-corrosion measures. Additionally, the electric heating tubes should be coated with anti-rust oil to ensure long-term performance.
The single-head heating tube, also known as an L-type single-head electric heating tube, is a special variant of the standard single-head type. It is commonly used in plastic packaging, small mold heating, injection nozzle heating, hot pressing machines, cigarette machinery, semiconductor eutectic welding, die casting tunnel heating, and sprue-free injection molding systems. It also plays a role in cooling effects when various gases expand.
Customization options for special-shaped single-head heating tubes include:
1. Material choices: Mainly SUS304, SUS321, and SUS316.
2. Pipe diameter: Can be manufactured according to customer specifications, ranging from 4mm to 25mm.
3. Tube length: Up to 2500mm.
4. Additional features: Lead length, fasteners, threads, and other custom elements can be tailored to meet specific requirements.
Through this detailed explanation, we hope to provide a clear overview of the technical features and customization possibilities of single-head heating tubes. If you need further assistance or have any questions, please don’t hesitate to reach out to us.

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.
