How to design an electric heating tube resistant to acid and alkali?

In industrial equipment, it is very common for electric heating tubes to heat acid-base liquids. The proper choice of acid-base electric heating tubes can extend the life of the electric heating tubes, extend the life of industrial equipment, and reduce the cost of industrial equipment. The specific design of the acid and alkali resistant industrial electric heating tube is still exquisite. Now I will introduce you with a general idea for your reference.

1. It is made of high-quality stainless steel (SUS316 or SUS304) electric heating tube inner core and outer Teflon tube (PTFE), which has strong corrosion resistance and is suitable for heating various corrosive liquids.

2. The shape is divided into vertical and bottom heating "L", "Z" shape.

3. Attention should be paid to the installation position of the electric heating tube to prevent solids in the solution from depositing on the surface of the heating tube, or the liquid is too thick or the liquid level is too low, which will burn out the Teflon tube (PTFE) due to poor heat dissipation on the surface

4. Low surface power design (1.5KW/CM2) to ensure the service life of the acid-base electric heating tube.

5. The acid-base electric heating tube is suitable for heating various corrosive liquids. It is a good choice for heating equipment such as electroplating, electrolysis, degreasing, pickling, electroless nickel, and phosphorus plating, anodizing, aluminum plating, smelting, chemical industry, medicine, etc. !
