       The most important part of the Resistance Bendable Tubular Heating Element work is the work of the heating wire. The quality of the heating wire determines the quality of the Resistance Bendable Tubular Heating Element. The research of the electric heating wire is to study the resistance value of the electric heating wire to determine the power of the electric heating tube. The resistance of the electric heating tube is fixed, and the different working voltages are applied, and the effects of different electric heating tubes are generated, and the thermal effect is also the same. Generally, the smaller the resistance, the larger the wire diameter of the resistance wire, and the larger the current through which the resistance wire passes when the voltage is fixed. When the current passing exceeds the load of the resistance wire, it is prone to breakage and damage, and the data indicates the heating tube. The resistance is not as small as possible, and the appropriate resistance wire should be selected according to the actual situation and to ensure normal use.


The heating pipe resistance value is confirmed 2 points:

1. Determine the rated voltage and rated power to determine the resistance. By formula: voltage * voltage / power = resistance.

2. The surface load of the heating wire is not to exceed the standard, and generally cannot exceed 1.5w/cm.

When selecting the electric resistance tube production value, it is mainly based on the rated voltage and rated power provided by the customer. At the same time, we must also consider the bearing capacity of the surface resistance of the electric resistance wire. Thereby ensuring the service life of theResistance Bendable Tubular Heating Element.


The 110V Tubular Heating Elements For Roaster is made up of a heating wire in a seamless metal pipe (carbon steel pipe, titanium pipe, stainless steel pipe, copper pipe), and the gap portion is filled with a magnesium oxide powder having good thermal conductivity and insulation, and then processed into a shrink tube. 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 environments. It can be used for heating various liquids and acid-base salts, as well as for metal melting and melting at low melting point (lead, zinc, tin, babbitt). Users can provide drawings for special design and processing.
