Immersion flange heating pipes are often used in industrial water tanks, heat-conducting oil furnaces, boilers and other liquid equipment. In the process of use, due to mistakes, they continue to heat even when the liquid is reduced. Such a result will often cause the heating tube to burn out, and in severe cases, an accident may occur. So what should we know, what should we pay attention to?
The heating tube is divided into liquid heating tube and dry heating tube because of its own surface load design is different. Generally, the surface load of liquid heating tubes is much higher than that of dry heating. Since the liquid electric heating tube is heated in the liquid, the heat on the surface of the heating tube is easily absorbed by the liquid, so that the surface temperature of the heating tube is not too high, so the surface load design of the liquid heating tube can be higher. The immersion flange type heating tube, because the working environment is in the air, the air itself has the negative effect of hindering heat conduction, so the surface load of the dry-fired electric heating tube is low. If the liquid electric heating tube is dry burning, the surface temperature of the heating tube cannot be dissipated immediately, and the heating tube will cause the internal temperature to be too high, which will cause the heating tube to burn out and cause serious tube bursting.
The quality of the heating tube has a direct relationship with the manufacturer, and care must be taken in the selection of the product.
