What are the types and specifications of electric heating tubes?

Electric heating tubes come in a variety of types and specifications. The detailed classification and specification introduction are as follows:

Types

By Shape

Electric heating tubes can be divided into long type, short type, round type, spiral type, U-type, W-type, special-shaped type and more.

By Material

Stainless Steel Electric Heating Tube: Common stainless steel grades include 304, 321, 316L, etc. These materials feature excellent corrosion resistance and high temperature resistance.

Teflon Electric Heating Tube: Also known as PTFE electric heating tube, commonly called tetrafluoride tube, it is widely used in corrosive liquids such as strong acid and strong alkali.

Titanium Electric Heating Tube: Commonly applied in processes such as passivation, chromium plating, acid copper plating, oxidation tank treatment and chromic acid anodizing.

Other available materials include carbon steel, 201 stainless steel, 310S stainless steel, and imported Incoloy materials.

By Application Scenario

Electric heating tubes are applicable for solid (metal) heating, liquid heating, gas heating and other purposes.

Specifications

The main specifications of electric heating tubes include pipe diameter, length, voltage and other parameters.

Pipe Diameter: Common pipe diameters are 2mm, 5mm, 6mm, 8mm, 10mm, 12mm, with the maximum up to 30mm. Under the same material and standard, the thicker the pipe diameter, the higher the cost of the heating tube.

Length: With the same material and pipe diameter, the longer the overall length of the electric heating tube, the higher the cost, as more raw materials are consumed with increased length.

Voltage: Common rated voltages include 110V, 120V, 220V, 380V, etc. The voltage selection depends on specific application and equipment requirements.

In addition, there are custom-specification electric heating tubes for different application scenarios and demands. Products used in foot massagers, glove-type clothes dryers, steam generators, electric soldering irons, electric heaters, fuel storage tank heaters, galvanizing tank heaters, boiler heaters, water bath heaters, mechanical heaters and other equipment all have exclusive specifications and power requirements.

When selecting electric heating tubes, comprehensive consideration shall be given to the actual application scenario, equipment requirements, budget and other factors, so as to choose the most suitable type and specification.
