The power setting mainly involves heating the electric heating tube and liquid. For dry burning, a one meter long tube is usually 1KW, while for heating the liquid, a one meter long tube is usually 2-3KW, with a maximum not exceeding 4KW.

3. Select heating tube material based on working environment

The most commonly used material for general customers is stainless steel 304 material. The working environment is generally divided into dry burning and liquid heating. If it is dry burning, such as for ovens and duct heaters, it can be made of carbon steel or stainless steel 304 material. If it is heating liquid, if it is water, use an electric heating tube. This stainless steel is usually made of stainless steel 304 material, and if it is oil, it can be made of carbon steel or stainless steel 304 material. If it contains weakly acidic and alkaline liquids, stainless steel 316 material can be used. If there are only strong acids in the liquid, stainless steel 316, polytetrafluoroethylene, or even titanium pipes should be used.

4. Select the shape of the heating tube according to the customer's electric heating equipment

The shapes of stainless steel heating pipes vary greatly, with the simplest being straight rods, U-shaped pipes, and even irregular pipes. Specific shapes of electric heating tubes are used for specific situations.

5. Determine the wall thickness of the heating pipe based on the usage of the customer's heating pipe

Generally, the wall thickness of heating pipes is 0.8mm, but according to the working environment of the heating pipes, such as high water pressure, seamless stainless steel pipes with thicker wall thickness are needed to make the heating pipes.
