Knowledge of stainless steel electric heating tube
The stainless steel electric heating tube is made of metal tube. The metal sheathed electric heating element can heat the air, metal mould and various 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. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safe and reliable, simple installation, long service life and so on. 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.
There are many varieties of stainless steel heating pipes used by the manufacturers of instant electric water heaters, and the price difference of various pipes is great. Stainless steel electric heating tube, the quality of the difference is also very large. The difference between the quality of stainless steel electric heating pipes is mainly due to the different nickel content. Nickel is an excellent corrosion resistant material, and the corrosion resistance and process performance of stainless steel are improved after the combination of chromium and chromium in stainless steel. But low carbon nickel steel to obtain pure austenite, nickel content reached 24%, and only 27% of nickel to steel corrosion resistance in some medium significant 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%. Therefore, 316L stainless steel bright rod using nickel content of high temperature corrosion resistant stainless steel heating tube products are also very advantageous.
