he general materials of outer pipe are in800, in840304316l, 310S, aluminum, copper, low carbon steel, etc.
Magnesia powder is selected according to different requirements, including high temperature powder, medium temperature powder, etc.
The resistance wire is a heating element, and generally there are two kinds of materials, Ni Cr wire and Fe Cr al
There are generally two kinds of lead terminal materials: stainless steel and easy to cut iron.
Sealing materials: epoxy, silica gel, glass, etc.
It is made of the outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube) filled with the electric hot wire, and the gap part filled with the magnesia powder with good thermal conductivity and insulation. After the heat treatment process (not required for some tubes), it is processed into various shapes required by the user. The utility model has the advantages of simple structure, high thermal efficiency, good mechanical strength and good adaptability to harsh environment. It can be used for the heating of various liquids and acid-base salts, and also for the heating and melting of metals with low melting point.
Scope of application: suitable for heating air, oil, water, chemical medium, hot pressing die, molten salt, alkali and low melting point alloy, etc. The utility model has the advantages of high thermal efficiency, long service life, high mechanical strength, convenient installation, safety and reliability, etc.
Appearance classification: heating pipe can be divided into: straight single end heating pipe, straight double end heating pipe, U-shaped heating pipe, W-shaped heating pipe, special-shaped heating pipe and spiral heating pipe according to different appearance
