The principle and usage of threaded installation of single head electric heating pipes

1、 Overview of threaded installation of single head heating pipe
Threaded installation of single head electric heating pipe structure: Weld a male (British) hollow bolt with hexagonal head (for fastening) of different sizes (determined by the customer) at the wiring part of the single head electric heating pipe. It can also be divided into two types: hexagonal head facing up and downward.
Usage: Widely used for heating various liquid materials, capable of withstanding pressure ≥ 0.8Mpa.
Recommended specifications: 8 ± 20 × 60 ± 1000
2、 Electrical strength of threaded single head electric heating pipes
The factors that affect the electrical strength of electric heating tubes mainly include the thickness of the insulation layer, the quality of the insulation layer's raw materials, the length of the heating tube, the bending radius, and the number of bends.
3、 Usage method for threaded installation of single head electric heating pipes
1. When heating air, the components should be arranged in a cross and uniform manner to provide good heat dissipation conditions for the components and allow the flowing air to be fully heated.
2. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media, and moisture.
3. The lead wire should be able to withstand the temperature and heating load of the wiring section for a long time, and excessive force should be avoided when tightening the wiring screws.
4. The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the use site to prevent leakage accidents.
4、 Instructions for ordering threaded single end electric heating pipes
1. Voltage, power, number of phases, and lead length of the electric heater;
2. The length, width, outer diameter of the electric heating tube, and the outer diameter, thickness, and number of holes of the flange should be provided for those with flanges,
3. Material requirements for electric heating pipes, flange materials, whether protection is required, etc
5、 Recommended surface load values for electric heating tubes
The following surface loads generally refer to the combination of metal mold heating and water heating, which can be multiplied by 2-2.5. Air heating is 50% to 60%.
Pipe diameter:? Load value (Wcm square)
φ 6~ φ 10 ≤ twenty-two
φ 10.1 to φ 14 ≤ twenty
φ 14.1~ φ 18 ≤ sixteen
φ 18.1 to φ 22 ≤ twelve
φ 22.1 to φ 40 ≤ ten
