Why must the air heating pipe have temperature control?

According to the working environment of tubular heater, tubular heater is generally divided into air heating pipe and liquid heating pipe. When customers come to us to inquire about the air heating pipe, we will ask whether the temperature control is available when the tubular heater is working?


Air heating pipe, we often choose materials are: ordinary carbon steel and stainless steel 304. If the gas contains corrosive gas, we will consider a better material. Normally, the heating effect of the two materials is almost the same. What's the difference between the two materials with great cost difference? Once the ordinary carbon steel is put aside for a long time, it will rust. Then the heating pipe is rusty and can not be used again. So in the long run, it is better to choose stainless steel 304. If air heating tube is used in the experiment, ordinary carbon steel material can be used. After all, it's cheap and doesn't need to be used for a long time.


Why do customers often report that the air heating pipe will be broken after several months of use. This reminds us that what we have to consider is temperature. In air heating tubes, the life is generally not high, that is, because the temperature is not well controlled, resulting in the heating tube internal temperature is too high, thus heating tube breakdown, and even tube burst. General dry burning heating tube, working temperature control between 200-300 degrees. If possible, a fan should be equipped to make the tubular heater dissipate heat evenly, so as to prolong the service life of the tubular heater.
