Stainless steel plate electric heating device is made of metal hose. This kind of metal material armored cable electric heating material can heat gas, metal material abrasive and all kinds of liquid. The stainless steel plate electric heating tube is made by putting electric heating material into the metal hose and adding crystalline magnesia powder with excellent temperature resistance, heat transfer and dielectric strength in the gap. It has the characteristics of simple structure, high impact toughness, high thermal efficiency, reliable, simple installation and long service life. It is widely used in all kinds of niter tank, stainless steel tank, oil tank, strong acid and alkali tank, fusible metal forging heating furnace, gas heat treatment furnace, dryer equipment, drying box, pressing die and other equipment.
That is to say, there are many kinds of stainless steel plate heating pipes used by manufacturers of fast heating domestic water heaters, and the prices of all kinds of pipes vary greatly. The same is stainless steel plate of electric heating tube, the quality characteristics of the difference is also very big. The main difference between stainless steel plate and electric heating pipe material is the content of nickel. Nickel is an excellent anti-corrosion material. The corrosion resistance and service performance of stainless steel plate can be improved by cooperating with chromium in stainless steel plate. However, in order to obtain pure martensite structure, the nickel content of low-carbon environmental protection nickel steel must reach 24%, and the corrosion resistance of steel in some substances can be obviously modified only when the nickel content is 27%. Therefore, in terms of materials, 800, 840 and 316L are good corrosion-resistant and heat-resistant stainless steel plate electric heating pipes. The nickel content of 800 stainless steel pipe reaches 30%, that of 840 pipe reaches 20%, and that of 304 stainless steel plate is 8%. Therefore, 316L stainless steel plate bright bar selection of high nickel content of heat-resistant and corrosion-resistant stainless steel plate heating tube commodity is also very good.
