Tubular electric heater is composed of a metal tube, spiral resistance wire, and electrical-grade magnesium oxide powder with good thermal conductivity and insulation, as well as lead terminals. It is widely used for heating liquids, air, etc. Common examples include water heaters, ovens, and coffee makers.
Materials:
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low-carbon steel, etc.
Magnesium oxide powder is selected according to different usage requirements, with high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, typically made of two materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally include two types: stainless steel and free-cutting iron.
