The heating medium is different, and the heating tube selected is also different. The material of the heating tube is also different in different working environments. Heating tubes can be roughly divided into air dry heating and liquid heating. In the use of industrial equipment, dry heating heating tubes are mostly divided into stainless steel heating tubes and finned electric heating tubes. Their common feature is the use of stainless steel material, the use of electric heating wire to heat, transfer the heat to the air, so that the temperature of the heated medium rises. (Note: There are also carbon steel heating tubes in industrial equipment. Due to the advantage that carbon steel is not easy to rust in extremely dry conditions, there are also heating tubes of this material on the market. However, experiments and research have found that carbon steel is not easy to rust. The steel heating tube is easily oxidized if it is not used for a period of time, and once it is oxidized and rusted, it will not work properly. Therefore, it is better to choose metal stainless steel.)
Although the heating tube allows dry heating, there is still a difference between a dry heating tube and a liquid heating tube.
Liquid heating tube. We need to know the height of the liquid level and whether the liquid is corrosive. The liquid heating tube must be completely immersed in the liquid during use, so as to avoid the phenomenon of dry burning of the electric heating tube, and the surface temperature is too high, which may cause the heating tube to burst. For ordinary softened water heating pipes, we can choose ordinary stainless steel 304 material. The liquid is corrosive. According to the corrosiveness, you can choose stainless steel heating pipe 316 material, Teflon electric heating tube, titanium tube, etc. Corrosion resistance The heating tube; if it is to heat the oil card, we can use carbon steel material or stainless steel material. The cost of carbon steel material is lower, and it will not rust when used in heating oil. Regarding the power setting, it is generally recommended that when heating water and other media, the power per meter should not exceed 4KW. It is best to control the power per meter at 2.5KW. When heating oil, it should not exceed 2KW per meter. If heating oil If the surface load is too high, the oil temperature will be too high and accidents may occur, so be careful. The phenomenon of scale and carbon formation on the surface of the heating tube needs to be observed regularly and measures should be taken to avoid affecting the heat dissipation and shortening the service life.
Dry heating heating tube. There are stainless steel heating tubes for ovens, single-head heating tubes for heating through mold holes, and fin heating tubes for heating air. Different shapes and powers are designed according to the customer's requirements. In general, the power of the dry-burning tube is set to not exceed 1KW per meter, and it can be increased to 1.5KW under the condition of fan circulation. From the point of view of the life of the dry-fired tube, it is best to have temperature control, which is controlled within the range that a tube can withstand, so that the tube will not be heated all the time, exceeding the temperature that the tube can withstand, no matter what the quality of stainless steel is. The heating tube will also be broken.
In conclusion, although the surface load of the air heating tube is lower than the surface load of the liquid heating tube, the production process of the air dry heating tube and the liquid heating tube is different and needs to be treated correctly. Customers can click on the dry heating tube or liquid heating tube to view the relevant pictures to purchase correctly. If you have technical consultation, you can call for consultation.
