The reason why the heating tube develops rapidly

- Aug 12, 2019-

As a basic heating element, electric heating pipes have developed rapidly in recent years. They have been widely used in both industrial production and civil household appliances, and can be seen frequently in everyone's daily life. So why is the development trend of the electric heating pipe manufacturing industry so fast?

The heating tube is different depending on the heating material. Different office environments, the material of the heating tube is also different. The heating pipe can be roughly divided into air dry burning and liquid heating. In the industrial machinery equipment application, the dry burning heating pipe is mostly divided into two types: a stainless steel heating pipe and a finned heating pipe. The same feature of each other is that the metal is made of stainless steel, and the heating wire is used to heat the heat to the air to promote the temperature of the heated material. Although the heating tube allows dry burning, there is a difference between the dry heating tube and the liquid heating tube.

Liquid heating tube: One must understand that the liquid level is high and the liquid is corrosive. The liquid heating tube must be thoroughly infiltrated into the liquid during the whole process to prevent the problem of dry burning of the electric heating tube. If the ambient temperature is too high, the heating tube may burst. If you give a general softened water heating tube, people use the general stainless steel 304 stainless steel material, the liquid contains corrosion, according to the size of the corrosion can choose stainless steel heating tube 316 material, Teflon electric heating tube, titanium tube, etc. If the oil is heated, people can use carbon steel or stainless steel. The cost of carbon steel is lower, and it is not easy to rust in the heating oil. If the surface load of the warming oil is too high, the water temperature will be too high, which is easy to cause a safety accident and must be cautious. The problem of dirt and carbonation on the surface of the heating pipe must be observed every quarter and taken to prevent damage to the heat pipe and reduce the service life.

Dry-burning heating tube: stainless steel heating tube for oven, single-head heating tube heated by grinding hole, finned heating tube for heating gas, can be different according to the specified design scheme and output power. The dry burning pipe is set to an output of not more than 1 kW per meter under normal conditions, and can be expanded to 1.5 kW in the case of a centrifugal fan circulation system. From the perspective of its service life, it is better to have a temperature control, which is controlled within a range that can be assumed by a water pipe, so that the water pipe is always heated, beyond the temperature that the water pipe can bear.
