Many, very many.
Industrial heating pipes have existed and developed for nearly a century. They were first invented in Europe and America, and then innovated in Japan. Now they have also been developed in China for decades. Domestic industrial upgrading has led to continuous product updates. Heating pipe products have been used as industrial auxiliary consumables. It is widely used, and the heating tube is basically indispensable for any link in industrial production that needs heating.
Heating tube can be divided into different shapes: long, short, round, spiral, U-shaped, W-shaped, etc.;
Classified by material: metal heating tube, ceramic heating tube, radiant heating tube, Teflon heating tube, etc.;
Divided by usage scenarios: for solid (metal) heating, for liquid heating, for gas heating, etc.;
2. Which is more practical?
This question is difficult to answer. The use of the heating tube has a lot to do with the environment, temperature, and purpose. It is not practical to specify a certain product in general. Industrial heating pipe products are never the most practical, only the most suitable.
For example, a single-head heating tube is suitable for use in a mold, because generally a mold product will use multiple heating tubes to work together, and even more than a hundred, the advantages of using a single-head heating tube: on the one hand, a single-head heating tube can be small The volume is high and the power is very efficient; on the other hand, the single-head heating tube is uniformly discharged from one end, which is very convenient for wiring.
For example, the use of immersion heating tubes in open water tanks: usually double-ended heating tubes are bent according to the shape of the water tank, and then used through multiple sets of combined wiring.
Another example is the use of flanges and threaded heating tubes in closed tanks: generally double-head heating tubes are used and assembled with flanges, threaded joints and other sealing structures to achieve heating and sealing effects.
Therefore, it is very important to contact professional manufacturers according to the usage situation, and then choose the most suitable products.
3. Introduction of heating tube application
We mentioned above that heating tube products are not the most practical but the most suitable. In the final analysis, it is because there are so many usage scenarios in industrial production that it is impossible to make a unified summary. Let’s try the simplest way-the shape of the heating object- Do a combing.
a. Heating solid (metal)
Application: sheet metal, extrusion, injection mold, casting mold, stamping mold, packaging, sealing machine, etc.
Related products: single-head heating tube, double-head heating tube, heating ring, heating film
b. Heating liquid
Application: water storage containers, oil tanks, inside flowing water pipes, heating outside pipes, heating corrosive liquids, etc.
Related products: double-head heating tube, immersion heater, corrosive liquid heater, heating ring
c. Heating gas
Application: pipeline, process gas, preheating gas, space insulation
Related products: fin heaters, air heaters, heating rings, heating plates
