How long is the U-type electric heating tube suitable?


The length of the single side of the electric heating tube is a very important parameter in the design of the heating tube. It not only determines the cost of the heating tube, but also determines the service life of the electric heating tube. Since the length of the single side of the electric heating tube is so important, what should we pay attention to when determining the suitable length of the U-shaped electric heating tube?


The precautions in the design of U-shaped heating pipe are as follows:


1. The single side length of the electric heating tube is generally designed according to the heating medium and power.

2. In horizontal installation, the length of the single side of the electric heating tube should not be greater than one meter, because under the action of gravity, the U-shaped electric heating tube will be concave after a long time. One way to solve this problem is to support the end of the pipe rack.

3. When installing vertically, if the liquid is heated, the cold zone (determined according to the liquid level height) should be considered. If the air is heated, the influence will be small, and it can be determined according to the normal power per meter standard.

4. The single side length of the electric heating tube should not be too long, otherwise the transportation is inconvenient and the transportation cost is very high.


The above is to determine the length of the U-shaped electric heating tube appropriate precautions, I hope to give you a little reference.
