Analysis of the precautions for purchasing conventional electric heating tubes

There are many types of electric heating tubes, and there are many things to pay attention to when purchasing and using them. Today we will take a detailed look at one of the issues - precautions for purchasing electric heating tubes.

First of all, we must fully understand the temperature requirements of each electric heating tube when it is used and choose a suitable device. In general, the greater the power, the faster the heating will be, and the shorter the heating time will be, and vice versa.

Dry burning is prohibited for electric heating tube equipment, especially for immersion electric heating elements, because such electric heating elements are made of stainless steel 304.

When choosing the power of the electric heating tube, it is necessary to ensure that the electric heating tube matches the power, provided that the effective use temperature must be guaranteed. Secondly, pay attention to the power load problem, and fully understand the use environment of the electric heating tube, whether it is medium conduction or infrared radiation, which is very helpful for our purchase.

You also need to fully understand the wiring method of the electric heating tube. There are generally two wiring methods for electric heating tubes: star connection and triangle connection. A single electric heating tube can be connected to 220V or 380V, and multiple electric heating tubes can be directly connected to 380V.

If you use a dry-burning stainless steel heating tube, you must pay special attention to the heat dissipation effect of the environment in which it is located. Generally, it can be divided into two situations: still air and flowing air.
