Temperature standard of different materials of tubular heating elements sheat:
Under the background of energy saving and emission reduction, heating pipes are used more and more. Among the heating pipes, metal electric heating pipes are the most widely used, and the general shell materials of metal heating pipes are also many, such as copper, iron and stainless steel, among which stainless steel heating pipes are the most widely used. According to the working environment of different electric heating pipes, the temperature allowed by different materials is also different. Now let's introduce the temperature standard of common materials of electric heating pipes:
First of all, first of all, the most commonly used materials of electric heating pipe are: copper, aluminum, carbon steel, stainless steel (SUS304, SUS321, SUS316, etc.), nickel based alloy steel, etc., which are mostly used.
Next, let's look at the maximum allowable temperature of different materials: the maximum temperature of copper electric heating pipe is 170 ℃; the maximum temperature of aluminum alloy electric heating pipe is 260 ℃, the maximum service temperature of carbon steel electric heating pipe is 400 ℃, the maximum service temperature of stainless steel electric heating pipe is 600 ℃, and the maximum service temperature of nickel base alloy steel electric heating pipe is 850 ℃.
The above data are from "JB / t2379-93 industrial electric heating tube standard", the theoretical data is only a rough data, the actual data can be consulted with our technical personnel.
