Heating pipe manufacturer to introduce electric heating tube shell material selection first depends on the heating medium
Single-head heating tube electric heating tube shell material selection first depends on the heating medium, for pipe in heating medium has good corrosion resistance, and then get a long use life.
Low single-head heating tube of various pipe materials on corrosion resistance of various heating medium see: liquid electric heater selection table
Low in the table above is for some corrosive liquid material, in fact in our normal industrial equipment, common primary is to heat water and air, and this kind of heating medium, we generally use the most extensive is stainless steel 304 stainless steel, stainless steel 321, stainless steel 316, 321 s, etc
Low single-head heating tube, stainless steel electric heating tube materials have many different trademark for stainless steel 304, 321 stainless steel, stainless steel 316 l, stainless steel 310 s, etc. Conventional alkali water and oil heating with stainless steel 304, there are some acid alkali liquid with 316 l stainless steel, acid alkali res 316 l stainless steel, however, from the point of view of heat-resistant, working temperature at 300 degrees or so commonly used stainless steel 304, the advice of the working temperature at 500 degrees using stainless steel 321, temperature and gao suggested using stainless steel 310 s. The above is purely personal experience, not accurate theoretical value, only for reference.
