Material:
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, including 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.
Process:
Heating Tube 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 required by the user. It has simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, and is also suitable for heating and melting low melting point metals.
Tubular heater application range: suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low melting point alloys. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, easy installation, safety and reliability.
Tubular heater shape classification: According to different shapes, heating tubes can be divided into: straight single-end heating tube, straight double-end heating tube, U-shaped heating tube, W-shaped heating tube, special-shaped heating tube, spiral heating tube.
