How to distinguish the quality of the heating tube

- Apr 20, 2019-

I. Insulation: The main reason for the insulation of the heating pipe is the sealing process of the heating pipe.

 

Second, leaking hair flow: mainly related to the temperature of the heat pipe used, the use of the heat pipe, the length of the heat pipe, and so on. An important assessment indicator for high temperature heating tubes.

 

Third, the power accuracy: mainly related to the quality of the resistance wire, the manufacturing process level of the manufacturer. A temperature coefficient test is required before mass production to determine the cold state resistance of the qualified power range.

 

Fourth, the life: the life of the heating tube is related to the quality of the resistance wire, but also related to the quality of the magnesium oxide powder, the choice of the diameter of the resistance wire. When selecting the diameter of the resistance wire, it is necessary to calculate the surface load of the resistance wire to meet the life requirement.

 

5. Heating intensity: The main factors affecting the heating intensity of the heating tube include the thickness of the insulating layer, the quality of the insulating layer, the length of the heating tube, the radius of the bending and the number of bending.
