Product Process:
U-shaped finned tubular electric heater is made by inserting 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 shrinking the tube. After heat treatment (some tubes do not require it), it is processed into various shapes as needed by the user. It has a simple structure, high thermal efficiency, good mechanical strength, and strong adaptability to harsh environments. It can be used for heating various liquids and acids, alkalis, and salts, as well as for melting low-melting-point metals.
Application Scope: Suitable for heating air, oil, water, chemical media, hot press molds, melting salts, alkalis, and low-melting-point alloys, etc. It features high thermal efficiency, long service life, high mechanical strength, easy installation, safety, and reliability.
Shape Classification: Heating tubes can be classified by shape into: straight single-end heating tube, straight double-end heating tube, U-shaped heating tube, W-shaped heating tube, special-shaped heating tube, and spiral heating tube.

Product Introduction:
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, 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 according to different usage requirements, including high-temperature powder, medium-temperature powder, etc.
The resistance wire serves as the heating element, and there are generally two materials: Ni-Cr wire and Fe-Cr-Al wire.
Lead terminal materials generally include two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
