How long is the service life of the electric heating tube:

The electric heating tube has a long service life, multiple protection systems, and is safe and reliable. Most of the combinations use argon arc welding to connect the electric heating pipe to the flange. The fasteners can also be in the form of a fastening device, that is, each electric heating pipe is welded to the fastener, the nut is fastened to the flange cover, and the pipe and The fasteners are welded by argon arc. Don't leak secrets. The fastener sealing part adopts science and technology, it is very convenient to replace a single one, which greatly saves future maintenance costs. Compared with ordinary metal heaters, it has stable electrical performance, high thermal efficiency, energy saving of more than 30%, and fast heating speed.

Features of open and closed solution tanks and flanged electric heaters for heating in circulating systems:

　　 1. Small size, large heating power; large surface power, 2 to 4 times the surface load of air heating.
2. Various media can be heated in various occasions, such as explosion-proof occasions; highly dense, compact structure. Because the whole is short and dense, it has good stability and no bracket is needed for installation.
3. Choose imported and domestic high-quality materials, scientific production technology, and strict quality management to ensure the superior electrical performance of the electric heating tube. The heating temperature can generally reach 720°C.
4. The heating system can be fully automated, including the control of the electric heating system through the DCS system.

Pure copper (oxygen-free copper) heater:

The oxidation resistance and corrosion resistance of red copper can not only reduce the harm of scale, but also have much better thermal conductivity than stainless steel. At the same time, the oxygen-free copper material has strong ductility, so the seamless pure copper pipe and copper pipe welding can be used. Reduce the number of welds, the potential of copper is much lower than the potential of impurity elements in the water, and it will not be subject to electric corrosion, which fundamentally eliminates the harm of scale and improves thermal efficiency. According to the <China Daily Appliance Quality Supervision and Inspection Center Electric Water Heater The latest inspection report and the test results related to water appliances by the Chinese Center for Disease Control and Prevention show that the oxygen-free copper heater has 100% antibacterial and anti-mildew properties in its material selection and design. Ranked first in the list of materials. However, the material cost of oxygen-free copper is 4 times that of stainless steel. The cost is too high, which affects its wide application in the instant electric water heater industry.
