1. Selection principles for high-temperature and corrosion-resistant pipelines:.

2. Selection of resistance wire.

3. Selection of magnesium powder.

4. Selection of sealing materials.

Firstly, stainless steel 301 is used in various high-strength applications because it hardens during processing and deformation. In the manufacturing process of stainless steel heating tubes, 304 stainless steel is widely used for heating liquids (without strong acids or bases) and air heating. Good comprehensive performance, easy molding, and moderate price. It is widely used in the manufacturing of heating tubes.

The 302 stainless steel material is actually a 304 variety, with high carbon content and high strength after cold rolling. 303 stainless steel is easy to cut because it contains sulfur. It is mainly used in situations where it is easy to cut and requires high surface smoothness of stainless steel.

Compared with 304 stainless steel, 304L stainless steel has a lower carbon content. When welding, low-carbon stainless steel with low carbon content is close to the weld seam, and the amount of carbides decomposed by heating is less, so carbon emissions are reduced because carbides can cause welding erosion. 305 material has a high nickel content, low work hardening rate, and is easy to shape. 308 stainless steel is commonly used to manufacture covered electrodes.

Scientific and rational use of fin electroformed aluminum heaters can prolong the service life of electric heating tubes

Scientifically and reasonably using fin cast aluminum heaters can expand the power supply and reduce the financial and labor costs of users. Based on our production experience, the following points can be summarized: Precautions for purchasing and using finned electric heating tubes:

The electric fin electric heating tubes used by many enterprise users are non-standard customized products. In fact, this is beneficial. You can make relevant requirements to the manufacturer. Students and we use this situation. The manufacturer will design the size and power of the finned electric heating tube according to your actual needs using different situations.

After the purchaser of the finned electric heating tube returns, if there are no issues with the enterprise, it should be used immediately and placed in a dry and cool warehouse; If the moisture analysis can be dried in a 180 ℃ oven for 4 hours, and if the finned electric heating tube is not used for a long time, it may produce false resistance, then the resistance of the finned electric heating tube can be measured by electrification.

Scientifically use electric heating according to heating conditions. Finned electric heating tubes used for heating water cannot be used for heating media such as air, high viscosity asphalt, and thermal oil, as these media have lower power per unit area, and using finned electric heating tubes to heat water can easily damage the finned tubes.

Finned electric heating tubes for heating liquids must pay attention to inserting all information about the heating area into the medium to avoid dry burning of different parts of the heating area in the enterprise; Meanwhile, we should also be able to design and provide corresponding non heating areas based on the thickness of the water tank inserted into the finned electric heating tube.
