In the heating elements market, you can see many different industrial electric heaters, such as, cartridge heater, coil heater, tubular heater, band heater, immersion heater, etc..
The main material is the stainless steel pipe.
Do you know what kind of the stainless steel pipe usually use for different electric heaters?
How to choose according to different application?
The stainless steel material is a very important factor in the life time and cost of the industrial electric heaters.
In the electric heating elements industry, the electric heater tube materials normal will be
stainless steel 201,
stainless steel 304,
stainless steel 316,
stainless steel 321,
stainless steel 310s.
They are divided according to the difference in the grades of stainless steel.
The difference between these grades of stainless steel determines the critical metal element of the use temperature and corrosion resistance of the electric heater is the nickel element in the stainless steel.
Nex, let us to see the advantages of different stainless steel types.
Stainless steel 201: Low cost, widely used in electric accessories, such as flange and mother flange, thread, fins, fasteners and so on.
Stainless steel 304: is the most widely used material of the electric heaters production, mostly for the electric heater shell. And if the customer requires, also be used as flange and mother flange, fins, fasteners material.
Stainless steel 316: widely used in a weak acid, or weak alkaline, corrosive heating environment, such as drinking fountains heater, boiler heater, medical equipment heaters.
Stainless steel 321: can withstand high temperature (operating temperature can be 500℃), good oxidation resistance. Extruder, and extruded tube heater use this material.
Stainless steel 310s: in high temperature (operating temperature about 800 ℃) can continue to work, with good high temperature resistance, good oxidation resistance. Furnace electric heaters are all to use this material.
The difference in the grade of stainless steel directly affects the performance of the electric heater. Now you can know how to choose the electric heater stainless steel pipe, and judge if the industrial electric heaters had used the appropriate stainless steel pipes.
