Electric heating tubes are divided into stainless steel finned electric heating tubes and metal tubular electric heating tubes according to shape and material.
Stainless steel finned heating tube, the shape is I type.
Stainless steel finned heating tube, the shape is U-shaped.
W-type finned heating tube, the shape is W-shaped.
Features of finned electric heating tube:
①The heating element is small in size, ②The temperature rises quickly, ③The heating is uniform, ④The heat dissipation performance is good, ⑤The thermal efficiency is high, ⑥Long service life, ⑦Low cost and so on. Often used for heating of still and flowing air.
The first type of metal tubular heating tube is called the steam generator flange heating tube.
The steam generator flange heating pipe is made of iron and galvanized (for replacement of heating equipment such as steamers and steam generators), and multiple heating pipes are welded or screwed to a flange to form a high-power The whole disassembled electric heating tube.
Application areas: clothing washing industry, food machinery industry, biochemical industry, packaging machinery industry, etc.
Not suitable for heating in oil.
The second type of metal tubular heating tube: called flat flange heating tube.
The characteristics of the flat flange heating pipe are similar to those of the threaded flange heating pipe, but the shape is different.
The third type of metal tubular heating tube: called threaded flange heating tube
The threaded flange heater is composed of SUS304 thickened stainless steel tube plus high temperature resistance wire plus high temperature insulation powder, ((reduces the surface load of the heating tube, used for heating in water and oil)) It refers to the If the heating level is required, multiple heating pipes are welded or screwed to a flange to form a high-power electric heating pipe that can be disassembled as a whole. It is widely used in heating equipment or places such as large water tanks, boilers, heat transfer oil furnaces, and reaction kettles.
When used for heating in water, the pH of the environment is high, and the water quality is too poor to change to a special coating.
When used for heating in oil, the temperature should not exceed 300 degrees Celsius.
