What is the difference between liquid heating tube and dry heating tube?

Home    软文    What is the difference between liquid heating tube and dry heating tube?

1. The difference in appearance:

Most of the liquid electric heating pipes are U-shaped or special-shaped electric heating pipes with fasteners, and flange electric heating pipes.

Dry-fired electric heating tubes are more common in single-ended straight rod electric heating tubes, U-shaped or special-shaped electric heating tubes without fasteners, finned electric heating tubes, and a very small number of flanged electric heating tubes.

 

2. The difference in power design:

1. The design of the liquid electric heating tube to determine the power according to the heating medium.

The power of heating water is 3KW per meter of the heating zone length of the electric heating tube.

When heating corrosive liquids and water that is harder and more prone to scale formation, the power per meter is about 2KW.

The maximum power per meter of heating oil is 2KW, and the power per meter of poorer and thicker oil is about 1KW.

2. The dry-burning electric heating tube is designed to determine the power according to the fluidity of the heated air:

The power of the dry-burning electric heating tube heated in a confined space is designed to be 1KW per meter.

The electric heating tube with fan circulation in the flowing space is designed to have a power of about 1.5KW per meter.

 

 

3. Different material choices:

1. Liquid electric heating tube

Oil:

Oil heating is normally made of stainless steel 304, but some customers who are used for experiments and pursuing low cost can also use carbon steel.

water:

Stainless steel 304 is used for heating tap water, and stainless steel 316 is used for drinking water. For turbid river water or water with more impurities, electric heating pipes with anti-scaling coating can be used for heating.

Corrosive liquid:

Stainless steel 316 can be used for liquids with relatively low alkaline acidity and weak corrosiveness.

2. Dry heating electric heating tube:

If it is not used for a long time, you can use carbon steel material for testing.

The working temperature is 100-300 degrees, and stainless steel 304 is recommended.

The working temperature is 400-500 degrees, and stainless steel 321 is recommended.

The working temperature is 600-700 degrees, and stainless steel 310S is recommended.

If the working temperature is around 700°-800°C, it is recommended to use imported materials from Ingles.
