The double-headed heating tube is a heating tube with a double-ended wire. The metal tube is used as a protective shell (including non-double-headed heating tube stainless steel, red copper tube, and various imported steel materials). The spiral high-quality electric heating alloy is uniformly distributed along the central axis of the tube Wire (nickel-chromium, iron-chromium alloy heating wire), and the gap is tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation. Both ends of the nozzle are sealed with silica gel and processed by other processes. . This kind of heating tube has two separate terminals, which is different from the general single-head heating rod, and the processing technology is also different. It is a form of heating tube element. The heater has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. With its strong advantages, it is widely used in molds, small pipes, sealing machinery, various ovens, baking rooms, and various liquid heating fields.

The common double-head heating pipes in industry are: straight double-head heating pipe, U-shaped heating pipe, double U flange mounting heating pipe, threaded mounting heating pipe, double-head fin heating pipe, double-head waterproof heating pipe, water boiler Heating tube, etc.
The following will make a brief statement on how to select parameters:
Double-headed electric heating rods are mainly divided into double-headed heating tubes and double-headed finned heating tubes. Of course, whether fasteners are needed can also be configured according to customer requirements.
1. Double-head heating tube size selection and equipment application matching selection:
The parameters that the customer needs to provide when placing an order: (preferably provide a drawing or ask the customer for the order parameter drawing for confirmation)
1. Voltage and power: customized according to the actual needs of customers.
2. Pipe diameter: commonly used pipe diameter Φ8-16MM.
3. Material: Commonly used materials are 10# iron and SUS304.
4. Tube length: refers to the length of the tube body.
5. Total length: as shown in the figure, it refers to the total length of the terminal with both ends (fasteners).
6. Accessories: If you don't need fasteners, customers must mark them.
Note:
For the parameters of tube length and total length, if the customer has no strict requirements, only the length of the tube body can be provided (fasteners and wiring parts are processed in accordance with normal procedures).
2. Double-head fin heating tube size selection and equipment application matching selection:
1. Voltage and power: customized according to the actual needs of customers.
2. Pipe diameter: commonly used pipe diameter Φ8-16MM.
3. Pipe material: commonly used materials are 10# iron and SUS304.
4. Fin material: commonly used materials are 10# iron, SUS201, SUS304.
4. Tube length: refers to the length of the tube body.
5. Total length: refers to the total length of the terminal with both ends (fasteners).
6. Accessories: If you don't need fasteners, customers must mark them.
Note:
1. Pipe length and total length parameters. If the customer has no strict requirements, only the length of the pipe body can be provided (fasteners and wiring parts are processed in accordance with normal procedures).
2. If the fin heating tube has requirements for the distance between the fin and the fastener position (that is, the fin-free part left at both ends of the fin after winding), it can be marked.
