Knowledge of stainless steel electric heating tubes

The stainless steel electric heating tube is made of metal tube. The metal sheathed electric heating element can heat the air, metal mould and all kinds of liquid. Stainless steel electric heating tube is placed in the heating element in a metal pipe, and the gap part tightly filled with good heat resistance, thermal conductivity and dielectric properties of crystalline magnesium oxide powder, in other treatment the. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life, etc.. Suitable for a wide variety of niter slot, water tank, oil tank, acid-base tank, metal melting furnace, heating furnace, drying oven, drying oven, hot pressing die device.

That is, the hot water heater manufacturers use stainless steel heating pipes, more variety, the price difference between the various pipes. The same stainless steel electric heating tube, the quality of its performance is also very different. The difference between the quality and the quality of the stainless steel electric heating tube is that the nickel content is different. Nickel is an excellent corrosion resistant material. After the stainless steel is combined with chromium, the corrosion resistance and the process performance of stainless steel have been improved. But low carbon nickel steel to obtain pure austenite, nickel content reached 24%, and only 27% of nickel to steel in some medium corrosion resistance significantly changes. Thus, 800, 840 and 316L from the material is compared to good corrosion resistance and high temperature resistant stainless steel electric heating tube, nickel content of 800 stainless steel tube to the 30% tube, 840 nickel content reaches 20%, the use of the nickel containing some 304 stainless steel tube as long as 8%. As a result, 316L stainless steel bright rod using nickel content of high temperature resistant corrosion resistant stainless steel heating tube products are also very advantageous.
