Heating tube selection should pay attention to these

1. Determine the thickness of the heating tube according to the application of the user's heating tube. The output power calculation function curve of the heating tube usually adopts a thickness of 0.8mm. However, according to the working environment of the heating tube, such as the case of high water pressure, it is required to use thicker seamless stainless steel tubes to make electric heating tubes.

2. When purchasing, ask the manufacturer clearly, why are many heating tubes made of internal materials similar in shape, but there is a huge price difference? It lies in the internal materials inside. The two most important materials inside are insulation powder and alloy wire. Insulation powder, the poor ones use quartz sand, and the better ones use insulating modified magnesium oxide powder. In addition, alloy wire, usually iron-chromium-aluminum, can be selected according to the requirements and levels of the tube. As the saying goes, you get what you pay for. It is recommended that the general public should not be greedy for cheapness and avoid purchasing defective electric heating tube products.

3. Generally, the most commonly used material by customers is stainless steel 304. The office environment is mainly divided into dry heating and liquid heating. If it is dry heating, such as for ovens and duct heaters, carbon steel or stainless steel 304 can be used. If it is to heat liquid, if it is water, take a stainless steel electric heating tube. This stainless steel is usually stainless steel 304. If it is oil, carbon steel or stainless steel 304 can be used. If it contains weak acid and alkaline liquids, stainless steel 316 can be used. If there is strong acid in the liquid, stainless steel 316, PTFE or even titanium tube should be used.

4. Use the shape of the electric heating tube according to the user's electric heating equipment. The shapes of stainless steel electric heating tubes are varied. The simplest is a straight rod, U-shaped and then special-shaped. Use electric heating tubes of specific shapes according to the specific situation.

5. Judge the power of the heating tube according to the office environment. The output power setting mainly includes liquid heating tube and dry-burning electric heating tube. For dry-burning, usually one meter long tube can produce 1KW. For heating liquid, usually one meter long tube can produce 2-3KW, and the maximum does not exceed 4KW.
