BGY4/BGY2 Constant Temperature Explosion-Proof Tubular Electric Heater Factory Direct Sales Overview
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 specifications such as high-temperature powder, medium-temperature powder, etc.
The resistance wire serves as the heating element, with two common materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally have two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Process:
The heating tube is made by inserting an electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then reducing the tube diameter. After heat treatment (some tubes do not require it), it is processed into various shapes as needed by the user. It has the characteristics of simple structure, high thermal efficiency, and strong mechanical
