Electric heating tube price

Anyone who understands electric heating tubes knows that the factor that determines how much the heating tube costs is not only the power but also many parameters. So which parameters determine the price of the heating tube? We list them one by one from the following categories.

Let's first take a look at the introduction and characteristics of the heating tube:

Introduction of electric heating tube:

Electric heating tube is made of a seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube) filled with electric heating wire, the gap part is filled with magnesium oxide powder with good thermal conductivity and insulation and then processed into Various shapes required by users. It has a simple structure, high thermal efficiency, and good mechanical strength. It has good adaptability to harsh environments. The electric heating tube can be used to heat various liquids and acid-base salts, and it is also suitable for heating and melting metals with low melting points.

Features of electric heating tube:

When the electric heating tube is made, the metal electric heating element is used as the heating element. According to the requirements of different heating tube power and voltage, the resistance wire is made into a spring shape with a winding machine, and then the electric heating wire is inserted into the seamless steel pipe, and then The casing is tightly filled with magnesium oxide powder with good insulation and thermal conductivity. Finally, the tube diameter is reduced by a tube shrinking machine. This manufacturing process can not only make the oxide medium dense but also ensure that the heating wire is isolated from the air so that it does not shift in the center position and touch the tube wall. Avoid electrical conduction or uneven heating on the surface of the electric heating tube.

1. Parameters affecting the price of Cartridge Heater:

1) Voltage and power are the most basic parameters of each heating tube (generally, it does not affect the price of the heating tube, but it is an important parameter that is indispensable in customized electric heating tubes).

2) Pipe diameter (thickness of the heating pipe, generally in mm) and length.

3) Working environment, working temperature (very important, decide the material of the electric heating tube, which will affect the price of the heating tube)

4) Lead length

5) Are there threads (if yes, what is the diameter and length of the thread)

2. Parameters affecting the price of U-shaped or special-shaped heating tube (Tubular Heater):

1) Voltage and power

2) Whether there are fasteners (what is the diameter of the fastener thread and what is the thread length)

3) Length of one side (if there are fasteners, measure the length below the threaded fastener)

4) Tube center distance

5) Pipe diameter

6) Working environment, working temperature

3. Parameters affecting the price of fin heating tube (Air heater):

1) Voltage, power

2) Shape (straight rod, U-shape, or other shapes)

3) With or without fasteners

4) Dimensions (straight bar: the length of the fastener is below the length of the fastener, and the total length without the fastener. U-shape: unilateral length, center distance. Other shapes: each length is measured)

5) Pipe diameter

6) Working environment, working temperature

4. Parameters affecting the price of Teflon heaters:

1) Voltage and power

2) Several U-shaped tubes

3) The unilateral length of a single U-shaped tube below the flange

4) Pipe diameter

5) Working environment, working temperature

6) Flange diameter, flange thickness
