Heating tube and heating rod
It is composed of a metal tube, a spiral resistance wire, and electrical grade magnesium oxide powder with good thermal conductivity and insulation, as well as lead terminals, etc. It is widely used for heating liquids, air, etc. Common applications include water heaters, ovens, coffee makers, etc.
Product materials:
Common outer tube materials include In800, In840, 304, 316L, 310S, aluminum, copper, low carbon steel, etc.
Magnesium oxide powder is selected in different specifications according to different usage requirements, such as high-temperature powder, medium-temperature powder, etc.
The resistance wire is the heating element, and there are generally two types of materials: Ni-Cr wire and Fe-Cr-Al wire.
Lead terminal materials generally have two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Product process:
It is inside the outer tube (
